2014 Yamaha FZ-09
Yamaha says:
Yamaha Motor Corporation, U.S.A. is proud to introduce the all-new FZ-09 for the 2014 model year.
Powered by a fuel-injected, 847cc liquid-cooled, 3-cylinder engine mounted in an aluminum frame, the FZ-09 brings an aggressive new model to the already vigorous Yamaha line-up.
This model was first revealed as an engine-only concept at the 2012 Intermot Motorcycle Show with this announcement: “With its clean torque output, this advanced new, light, slim and compact 3-cylinder engine will shape Yamaha’s future motorcycle line up.” Indeed, the 2014-model FZ-09 is a bold new model with a unique engine and look, and it’s packed with high-performance features.
Performance components such as Yamaha’s YCC-T ride-by-wire throttle system, D-mode with 3 throttle position settings, adjustable suspension and variable throttle intake lengths are combined with the 3-cylinder Crossplane Concept crankshaft configuration for an even firing interval that provides plenty of smooth, linear torque. The result is a sound and experience like no other motorcycle on the market.
The FZ-09 will be available in two color options—Liquid Graphite and Rapid Red––and will retail for $7,990, with bikes available in dealerships starting in September.
Features
- Introducing an all-new 847cc liquid-cooled, in-line 3-cylinder, DOHC, 12-valve engine with fuel injection. This engine combines advanced high tech components including YCC-T® and Yamaha D-Mode, with a crossplane concept crankshaft to deliver an exciting, torquey and quick-revving engine character.
- This 3-cylinder engine features Yamaha’s “Crossplane Crankshaft Concept” that provides linear torque development in response to the rider’s throttle input. Among the advantages of the in-line 3-cylinder engine are: (1) linear torque development, (2) even firing intervals that provide smooth torque characteristics and a good feeling of power in the low to mid rpm range, (3) a light, slim and compact design, and (4) performance that combines the characteristics of both 2-cylinder and 4-cylinder engines.
- To reduce vibration and deliver a smoother ride, the engine has a primary coupled-force balancer that revolves in the opposite direction and at the same speed as the crankshaft.
- A new 6-speed transmission has also been adopted to match the new engine. The transmission has optimized gear ratios that help to deliver engine torque efficiently. The result is a transmission that helps bring out more of the low- to mid-speed torque and excellent response characteristics.
- The ride-by-wire Yamaha Chip Controlled Throttle (YCC-T) system senses the slightest throttle input by the rider, relays the data to the ECU, which instantaneously calculates the ideal throttle valve opening based on engine rpm and throttle opening, and then sends commands to a servo-motor actuator that moves the throttle valve which actively controls the intake airflow volume. This is a technology contributing to the rider’s feeling of torque and controllability from the new 3-cylinder engine.
- Electronic fuel injection has been adopted to provide outstanding drivability. 12-hole injectors attached directly to the cylinder head deliver a highly pressurized spray of atomized fuel with droplets as small as a few microns. This enables high-precision injection directed at the valve skirts that contributes to optimum fuel combustion resulting in outstanding drivability and performance.
- The FZ-09 is equipped with Yamaha D-MODE (or “Drive Mode”) variable throttle control system to allow the rider to choose the optimum engine character for their riding situation. The rider can choose at will from three throttle valve control maps (Standard Mode, “A” Mode, and “B” Mode) for different performance characteristics. Operation is performed by a button on the handlebars. STD Mode is set to accommodate a wide range of riding conditions. In this mode the rider can enjoy the 3-cylinder engine’s linear torque feeling from low speeds all the way up to high speeds. A Mode lets the rider enjoy sharper throttle response in the low-to mid-rpm range than the STD Mode. B Mode lets the rider enjoy milder throttle response than the STD Mode for more relaxed power characteristics.
Engine:
- This lightweight liquid-cooled, 847cc, 4-stroke, in-line 3-cylinder, DOHC, 4-valve engine with downdraft intake and fuel injection is all new. With a 78 x 59.1mm bore x stroke and 11.5:1 compression ratio, it produces an exciting, torquey and quick-revving engine character.
- Some of the advantages of the 3-cylinder engine in the FZ-09 include linear torque development due to the even firing intervals that provide smooth torque characteristics and a good feeling of power up into the low to mid rpm range, as well as combining desirable characteristics of both 2-cylinder and 4-cylinder engines. In addition, the engine design can be light, slim and compact.
- To reduce vibration and help give a smoother ride, the engine has a primary coupled-force balancer that revolves in the opposite direction and at the same speed as the crankshaft.
- The connecting rods are made using the fracture split (FS) method to ensure a high degree of circular precision in the rod’s big-end ring for a precise fit and smoother crank revolution. The fracture split (FS) method is where the big-end ring of a forged connecting rod is split in two by applying a sharp impact. This creates a perfectly matching split surface that naturally produces a much more precise mating surface when they are bolted together again around the crankshaft.
- To provide both exciting and quick revving torque characteristics and a unique intake sound, the 3-cylinder intake funnels have been designed with uneven lengths. The first cylinder funnel is 102.8mm, the second 82.8mm and the third is 122.8mm. This combines with the effects of the YCC-T system to contribute to an excellent torquey engine character.
- The FZ-09 transmission takes full advantage of the low-to-mid-range torque and excellent response characteristics of this in-line, 3-cylinder fuel-injected engine. The 6-speed transmission has been designed to be very compact, enhancing the overall narrow 3-cylinder design.
Chassis/Suspension:
- The wheelbase, seat height, fuel tank width, rake and other dimensions are all set to work with the qualities of the compact 3-cylinder engine to achieve a sporty, light and neutral handling character, an upright riding position and a narrow feeling chassis at the seat/tank junction.
- For excellent damping characteristics, the front suspension is an inverted fork with 41mm inner tubes with 5.4 inches of travel. The front suspension features adjustment for spring preload and rebound damping.
- The rear suspension features a linked-type Monocross® shock. The shock is positioned below the seat and features an almost horizontal alignment. This unique positioning contributes to mass centralization and a slimmer body design. The rear suspension is also adjustable for spring preload and rebound damping. These adjustments allow for different riding conditions and rider preferences.
- Newly designed, 10-spoke lightweight cast aluminum wheels are used, fitted with a 120/70ZR17 front tire and 180/55ZR17 rear tire. The tires have been designed with an optimally-tuned internal structure that contributes to good handling stability.
- Front brakes consist of two floating 298mm discs with 4-pot opposed piston calipers. The newly designed calipers are radial mounted.
Additional Features:
- The aluminum, tapered-type handlebars – a first for a Yamaha sportbike – provide a good balance of strength and light weight.
- The fuel tank, with its deeply recessed knee grip area, contributes to a narrow seat/tank juncture.
Newly designed, compact, hexagonal-type rearview mirrors match the “mass forward” design of the rest of the bike.
- A newly designed lightweight, compact, full LCD instrument panel is adopted. The tachometer has a digital bar-type display with gear position indicator. The electric starter button is a new slide-type that incorporates the engine cut-off switch is an integrated button for a modern and high quality appearance.
- The brake pedal, shift pedal, and footrests are made of forged aluminum for light weight and excellent appearance.
- The LED taillight has separate left and right lamps that illuminate when the taillight is on and across the entire lens when the brake light is on.

Yamaha Motor Corporation, U.S.A. is proud to introduce the all-new 2014 YZ450F and YZ250F.
Yamaha has led the modern motocross bike movement, beginning with the YZ400F in 1998 and continuing in 2001 with the YZ250F. Not content with that, the needle was moved again with the introduction of the revolutionary 2010 YZ450F, with its unique rearward-slanted engine design and “swapped” intake and exhaust layout. Still, Yamaha is not a company to rest on past achievements.
For 2014, the YZ450F is all new from the ground up, using the previous award-winning engine layout and then taking it to a whole new level with an all-new engine, chassis, suspension, unmatched mass centralization and look that will define the next generation of motocross bikes.
The 2014 YZ450F was designed with the racer in mind. Enormous power on tap whenever and wherever you need it, but still with the control required to put in smooth, fast laps, and KYB SSS suspension that encourages you to go faster and hit bumps harder, all in pursuit of beating your competition. Not to mention the world-renowned durability that is second to none, insuring that you will be out at the track week in and week out.
What’s even better than an all-new YZ450F, how about an all-new YZ250F to go along with it.
For 2014, the YZ250F is all-new, with Yamaha engineers taking everything they’ve learned along the way to create an all-new engine, chassis, suspension, unmatched mass centralization and look that, along with the YZ450F, will define the next generation of motocross bikes.
The 2014 YZ250F begins with fuel injection at the heart of an all-new rearward slanted engine with the same unique front intake and rear exhaust layout that has been so successful on the YZ450F. Combined with a 4-valve head design, the engine puts out plenty of mid to top end power to get you the holeshot. A new frame, along with class-leading KYB SSS suspension make sure the YZ250F carves every corner and absorbs every bump and rut thrown at it.
Both the 2014 YZ450F and YZ250F will be supported with a full line of GYTR and Genuine Yamaha Parts and Accessories, including the game-changing GYTR Power Tuner, to give you exactly the power and look you want while you’re out on the track.

Features
- YZ450F’s revolutionary rearward-slanted-cylinder design is an innovative approach to achieve unmatched mass centralization. Concentrating the motorcycle’s heaviest components (engine mass, fuel tank, exhaust system, and airbox) toward the center of the machine helps achieve superior, nimble handling.
- The 4-titanium-valve cylinder head is matched to a newly recalibrated fuel injection system to provide superb power feeling across the rpm range. The adjustable fuel injection system uses a 44mm throttle body fed by a high pressure battery-less electric pump to ensure optimum fuel atomization and air/fuel calibration for excellent readability in a wide range of riding conditions. The YZ450F instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions.
- The new aluminum Bilateral Beam frame offers a superb rigidity balance and, with new settings to already class leading front and rear suspension, provides unmatched lightweight handling and cornering. For 2014, the steering head pipe is moved 10mm closer to the rider, making for a more compact chassis dimension and placing more weight bias on the front wheel which translates to an even more precise and instinctive handling character.
- Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons.
Engine:
- For 2014, the top end - piston, intake, and exhaust valves and ports, valve mechanism, ignition timing, and fuel injection mapping - have all been meticulously revised, resulting in improved combustion and outstanding engine performance throughout the power band, with a focus on controllability.
- The new high-performance ECU provides great bottom end torque plus delivers a strong feeling of power from 3rd gear up while new gear ratios also lengthen the powerband and heighten the feeling of power in 2nd and 3rd gear.

- The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaustpulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This new layout allows the silencer to be positioned 186mm further forward behind the side panel closer to the middle of the bike which centralizes the mass for superior handling.
- The compact wet sump lubrication system with piston cooler spray jet eliminates the need for an oil tank, reducing engine weight. The water pump employs a plastic resin impeller for further weight reduction. The reduced size of the crankcase enabled by this lubrication system design is a major factor in making it possible to mount the 450cc engine on the newly designed compact frame to deliver precise and instinctive handling.
- Newly designed transmission and shift mechanisms provide quicker, smoother shifting under power with less effort.
- The accessory GYTR Power Tuner can simplify the work of adjusting fuel injection volume and ignition timing settings to fit personal preferences or track conditions.
Chassis/Suspension:
- A newly designed aluminum Bilateral Beam frame is adopted in which the head pipe is moved 10mm closer to the rider. The overall dimensions are roughly the same as the frame of the 2013 YZ250F. This gives the YZ450F a new compact chassis that provides the most instinctive handling in the 450 motocross class.
- The aluminum muffler is positioned closer to the machine’s center of gravity as it is almost completely hidden by the side number plate. The layout allows a shorter, lighter sub frame and also contributes to mass centralization for lightweight handling feel.
- The front suspension has proven KYB® air-oil separated forks. It adopts new spec inner and outer tubes coupled with optimized suspension settings. The new rear suspension also features a new reservoir location and spring spec with settings optimized for ideal damping characteristics to match the new chassis dimensions.

2014 Yamaha YZ450F
Yamaha says:
Yamaha Motor Corporation, U.S.A. is proud to introduce the all-new 2014 YZ450F and YZ250F.
Yamaha has led the modern motocross bike movement, beginning with the YZ400F in 1998 and continuing in 2001 with the YZ250F. Not content with that, the needle was moved again with the introduction of the revolutionary 2010 YZ450F, with its unique rearward-slanted engine design and “swapped” intake and exhaust layout. Still, Yamaha is not a company to rest on past achievements.
For 2014, the YZ450F is all new from the ground up, using the previous award-winning engine layout and then taking it to a whole new level with an all-new engine, chassis, suspension, unmatched mass centralization and look that will define the next generation of motocross bikes.
The 2014 YZ450F was designed with the racer in mind. Enormous power on tap whenever and wherever you need it, but still with the control required to put in smooth, fast laps, and KYB SSS suspension that encourages you to go faster and hit bumps harder, all in pursuit of beating your competition. Not to mention the world-renowned durability that is second to none, insuring that you will be out at the track week in and week out.
What’s even better than an all-new YZ450F, how about an all-new YZ250F to go along with it.
For 2014, the YZ250F is all-new, with Yamaha engineers taking everything they’ve learned along the way to create an all-new engine, chassis, suspension, unmatched mass centralization and look that, along with the YZ450F, will define the next generation of motocross bikes.
The 2014 YZ250F begins with fuel injection at the heart of an all-new rearward slanted engine with the same unique front intake and rear exhaust layout that has been so successful on the YZ450F. Combined with a 4-valve head design, the engine puts out plenty of mid to top end power to get you the holeshot. A new frame, along with class-leading KYB SSS suspension make sure the YZ250F carves every corner and absorbs every bump and rut thrown at it.
Both the 2014 YZ450F and YZ250F will be supported with a full line of GYTR and Genuine Yamaha Parts and Accessories, including the game-changing GYTR Power Tuner, to give you exactly the power and look you want while you’re out on the track.
The 2014 YZ450F is available in Blue or White/Red for $8,490 and is available the end of June. The 2014 YZ250F is available in Blue or White/Red for $7,490 and will be available in October.
Features
- YZ450F’s revolutionary rearward-slanted-cylinder design is an innovative approach to achieve unmatched mass centralization. Concentrating the motorcycle’s heaviest components (engine mass, fuel tank, exhaust system, and airbox) toward the center of the machine helps achieve superior, nimble handling.
- The 4-titanium-valve cylinder head is matched to a newly recalibrated fuel injection system to provide superb power feeling across the rpm range. The adjustable fuel injection system uses a 44mm throttle body fed by a high pressure battery-less electric pump to ensure optimum fuel atomization and air/fuel calibration for excellent readability in a wide range of riding conditions. The YZ450F instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions.
- The new aluminum Bilateral Beam frame offers a superb rigidity balance and, with new settings to already class leading front and rear suspension, provides unmatched lightweight handling and cornering. For 2014, the steering head pipe is moved 10mm closer to the rider, making for a more compact chassis dimension and placing more weight bias on the front wheel which translates to an even more precise and instinctive handling character.
- Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons.
Engine:
- For 2014, the top end - piston, intake, and exhaust valves and ports, valve mechanism, ignition timing, and fuel injection mapping - have all been meticulously revised, resulting in improved combustion and outstanding engine performance throughout the power band, with a focus on controllability.
- The new high-performance ECU provides great bottom end torque plus delivers a strong feeling of power from 3rd gear up while new gear ratios also lengthen the powerband and heighten the feeling of power in 2nd and 3rd gear.
- The valve mechanisms and cylinder head feature new specs that take performance to the next level. Intake and exhaust valves are enlarged and the cam profile for the intake has been modified, all contributing to improved combustion, resulting in added power and outstanding performance.
- The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaustpulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This new layout allows the silencer to be positioned 186mm further forward behind the side panel closer to the middle of the bike which centralizes the mass for superior handling.
- The compact wet sump lubrication system with piston cooler spray jet eliminates the need for an oil tank, reducing engine weight. The water pump employs a plastic resin impeller for further weight reduction. The reduced size of the crankcase enabled by this lubrication system design is a major factor in making it possible to mount the 450cc engine on the newly designed compact frame to deliver precise and instinctive handling.
- Newly designed transmission and shift mechanisms provide quicker, smoother shifting under power with less effort.
- The accessory GYTR Power Tuner can simplify the work of adjusting fuel injection volume and ignition timing settings to fit personal preferences or track conditions.
Chassis/Suspension:
- A newly designed aluminum Bilateral Beam frame is adopted in which the head pipe is moved 10mm closer to the rider. The overall dimensions are roughly the same as the frame of the 2013 YZ250F. This gives the YZ450F a new compact chassis that provides the most instinctive handling in the 450 motocross class.
- The aluminum muffler is positioned closer to the machine’s center of gravity as it is almost completely hidden by the side number plate. The layout allows a shorter, lighter sub frame and also contributes to mass centralization for lightweight handling feel.
- The front suspension has proven KYB® air-oil separated forks. It adopts new spec inner and outer tubes coupled with optimized suspension settings. The new rear suspension also features a new reservoir location and spring spec with settings optimized for ideal damping characteristics to match the new chassis dimensions.
- The new larger diameter 22mm front axle and new top triple clamp increase rigidity for improved handling and front end feel. The handlebar mounts are now rubber mounted to improve comfort and reduce handlebar vibration.
- A new layout for the fuel tank and air cleaner box gives the machine a slimmer feeling between the legs as well as positions fuel tank mass closer to the center of the bike which improves handling feel. Furthermore, the air box can now be accessed without removing the fuel tank for easy serviceability of the new larger air cleaner element.
- A new narrower radiator design contributes to slimming down the radiator panel area.
Additional Features:
- “In-mold graphics” technology is a method in which the graphics are molded into the radiator shrouds for improved decal durability and reduced scratches.
- Riders have a choice of two color options: Team Yamaha Blue/ White or White/Red.

Even fans of the previous YZ250F will be sure to notice the solid handling characteristics, including the light feel in tight corners and during direction changes.
- The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaust pulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This new layout allows the silencer to be positioned 190mm further forward, behind the side panel, making it closer to the middle of the bike for centralized mass for superior handling.
- The all-new layout of the seat, fuel tank, air box, and wrap-around exhaust system moves the bike’s mass towards the center for exceptional handling. And, in addition to an all-new appearance, the front intake layout with larger air filter element adds the benefit of reduced air filter maintenance due to its positioning away from dirt roost from the rear wheel.
- Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons.
Engine:
- A new liquid-cooled, DOHC 4-valve, fuel-injected engine with the same forward-positioned straight intake, rear-inclined cylinder and rear-positioned exhaust layout as the YZ450F. The new engine, with its straight and symmetrical intake and exhaust ports and compact, high-compression combustion chamber, delivers outstanding engine character with more power output and deeper power in the high-speed range.
- The new, adjustable fuel injection system uses a 44mm throttle body fed by a high-pressure battery-less electric pump to ensure optimum fuel atomization and air/fuel calibration for excellent readability in a wide range of riding conditions The system provides 3-dimensionally mapped control of the volume of fuel injected and the ignition timing based on engine rpm and throttle opening. This ensures hesitation-free response and controllability and contributes to the high level of high-rpm power.
- Various detailed design measures are adopted to reduce horsepower loss. The forged 2-ring piston is light weight and is cooled by an oil spray jet. In addition, the compression ring is a singlering design instead of the conventional two ring. This new piston and rings, along with the offset cylinder configuration reduce friction loss and contribute to quicker response. What’s more, the new specs for the intake/exhaust ports, new cam profiles, new ECU, new carburized crank, optimized balance ratios for the crank web, the newly designed transmission, strengthened clutch design, and other features, all work together to create the YZ250F’s outstanding engine character with more power output and deeper power in the high-rpm range.
- As with the YZ450F, an innovative exhaust pipe design is adopted to increase mass centralization and improve power development characteristics. This layout moves the rear end of the exhaust pipe farther forward and enables a muffler position that is closer to the machine’s center of gravity. Adjustments are made in the pipe diameter in its various sections resulting in excellent exhaust pulse effect that contributes to stronger high rpm power output.
- The compact wet sump lubrication system with piston cooler spray jet maintains excellent engine durability and eliminates the need for an oil tank, which lowers engine weight. This creates a more compact engine that contributes to mass centralization and unmatched handling.
- Newly designed transmission and shift mechanisms reduce drive-force loss during gear changes and produce smoother shift operations and surer shift action.
