Kawasaki Announces All New 2017 KX250F and KLX140G

Kawasaki released some of their 2017 lineup today including an all new 2017 KX250F and KLX140G.
KMC tells us that the new KX250F comes in a new lighter weight package and narrower frame and sports a new and more powerful engine.

Adding to the KLX family is the new KLX140G that surprisingly utilizes both a kickstarter as well as a keyless electric start. Shipping with full size off road wheels, Kawasaki's latest trail bike will be a bonus for beginner riders.

Returning unchanged 2017 models include the KX450F, KX100, KX85, KX65, KLX110/L, KLX 140L. FUll details and specs for the 2017 KX250F and KLX140G below...


The all-new KLX140G motorcycle is a lightweight full-size trail bike designed to let the pureness of dirt riding shine through. New for the 2017 model year, the KLX140G comes with full size off-road wheels and tires, a powerful and durable 144cc 4-stroke, air-cooled, single-cylinder engine, electric starter and keyless ignition. Its ergonomics and lightweight chassis make it ideal for taller riders who want to experience the KLX140G. Built to provide newer and more experienced riders alike great off-road performance in a bike that fits well and is easy to ride, the KLX140G is all about pure fun in the dirt.

The KLX140G is lightweight, has a low seat height, broad and smooth high-revving 140cc engine with a manual clutch, 5-speed transmission. These factors make it a great off-road motorcycle for a wide range of riders. From the younger or less experienced riders advancing their riding skills, to their parents wanting a bike to join them on the trails, it’s a capable and unintimidating motorcycle designed to deliver unlimited fun.

The Kawasaki KLX140G:
• 144cc air-cooled, 4-stroke engine w/ manual clutch and 5-speed transmission
• Keyless ignition and electric starter
• Full size, 21-inch front and 18-inch rear wheels, off-road wheels and tires
• Low seat height at 33.8 inches
• Light weight, 218 pounds curb weight
• Front and rear petal-style disc brakes

The KLX140G motorcycle is ideal for a variety of riders. The new KLX140G was designed to encourage inexperienced riders to get out and have fun, without the worry of a motorcycle that is too heavy or skills intensive. The KLX140G is built to be an unintimidating step up through the Kawasaki KLX and KX™ motorcycle families. The new full size wheel and tire combination and enhanced maneuverability make it fun for experienced riders too.


• Electric start - Keyless CDI ignition with ON/OFF kill switch
• 4-stroke air-cooled single-cylinder engine
• 58.0 x 54.4mm bore and stroke
• Muffler comes equipped with spark arrester
• 5-speed transmission and manual clutch

The KLX140G offers a reliable compact power plant that is simple to operate and maintain. With a 144cc engine it delivers plenty of power through the rev range. A progressive manual clutch offers new riders the chance to experience full control of gear shifting. The clutch features a spring damper resulting in a progressive, 2-stage engagement that facilitates half-clutch use when riding at extremely low rpm or idling speeds, making it great for technical riding. Additional benefits are a direct, but light feel and high durability.
The KLX140G comes standard with a spark arrester, which is a must for trail riding. Having this as a standard feature is another way Kawasaki has made the KLX140G a trail-ready motorcycle. No worries, just riding.

Another major factor that makes the KLX140G ideal for almost any level rider is the addition of an electric starter, utilizing a keyless ignition. It still retains a kick-starter for those riders who are learning or for when a backup is needed.


• 33mm telescopic front forks
• Adjustable Uni-Trak® rear suspension
• Box-style, high tensile steel frame
Combined with the highly rigid frame is the capable suspension that helps ensure steady handling and feedback, contributing to the KLX140G’s high level of off-road fun. First is the box-style, high-tensile steel perimeter frame, which provides a rigid, lightweight and narrow chassis for easy handling or spirited riding.
Up front you’ll find 33mm telescopic front forks with 7.5 inches of wheel travel with a Uni-Trak rear suspension that has 7.9 inches of wheel travel. This adds up to capable and fun riding over a variety of terrain.
The rear shock features a piggyback reservoir, aluminum shock body and reservoir, fully adjustable preload, 4-way compression damping, and 22-way rebound damping.

• Styling inspired by the KX motorcycle
• Comfortable seat, handlebar and footpeg placement
• Narrow frame
• Integrated fit and finish
The racy styling of the new KLX140G was inspired by the design of Kawasaki’s KX motocross racers. The sharp, aggressive design is backed up by great trail-riding potential thanks to the box-section perimeter frame, adjustable suspension, front and rear disc brakes and full size wheels.
Two-piece “radiator shrouds” with ventilation holes contribute to a sporty, lightweight image. An additional cover over the tank ensures a flush transition from tank to shroud, contributing to the high level fit and finish.
A combination of form and function, the narrow frame and open ride position makes the bike maneuverable and fun to ride no matter the rider’s stature. Large footpegs provide ideal grip making it easy for riders to keep their feet on the pegs. The footpegs are positioned close to the bike’s centerline to create a slim riding position. The flat design of the tank and seat gives the rider greater freedom of movement when changing riding position.
The handlebar is rubber-mounted to reduce vibration transferred to the rider’s hands for enhanced comfort. Handlebar grips feature a raised pattern on half of the surface making them comfortable and easy to grip. Like the KX racers, the KLX140G motorcycle features a stylish two-tone seat cover that uses a slip-resistant top surface for good grip when seated and smooth sides for excellent rider mobility.


Kawasaki offers a wide variety of small displacement off-road motorcycles:
• KLX110
• KLX110L

The new Kawasaki KX250F motorcycle packs more power, better handling and less weight
to provide a bike that builds champions.

The Kawasaki KX250F is the single-most dominant motocross bike of the last decade. To keep riders on the podium, Kawasaki introduces an all-new KX250F for 2017, in line with the updates of the KX™450F motorcycle last year. The 2017 model offers a more powerful engine, a significantly lighter chassis, and slimmer ergonomics, making this new model the fastest KX250F motorcycle yet.

The 2017 Kawasaki KX250F:

Lighter weight (229.9 pounds)
New more powerful and lighter engine
New redesigned more narrow and lighter weight frame
Improved clutch and shift feeling 

New flatter seat and a new lower/flatter tank, for improved handling and ergonomics 

This year’s KX250F is built with race-winning components to keep Kawasaki riders in that top spot at the race track. From the showroom to the racetrack, the performance of Kawasaki’s KX family of motorcycles is proof of its engineering pedigree. It truly is the bike that builds champions.


New redesigned engine with offset cylinder layout, for more efficient power
Lighter bridged-box bottom piston, designed from racing experience
Downdraft-style intake layout with new injector angle designed for optimum fuel atomization
New downstream injector with twice as many holes, finer fuel droplets and wider angle, resulting in stronger low-to-mid power and sharp response
New and improved combustion chamber configuration
New 43mm throttle body

Tuned to best suit race-experienced riders, the 249cc liquid-cooled, 4-stroke single’s wide power-band focuses on high-rpm performance that extends way into the over-rev. Highly acclaimed for its high output and smooth power delivery, the 2017 model KX250F has race-inspired tuning and parts like the high-performance bridged-box bottom piston and down draft-style intake routing. Mechanical friction is reduced thanks to things like an offset cylinder—with increased forward lean angle—and plateau honing, resulting in a stronger low end as well as an increase in maximum peak power. The connecting rod now features a journal bearing in lieu of a needle bearing and items like the camshaft sprockets and chain have been revised along with a newly revised exhaust camshaft, all factors resulting in more efficient power.

The KX250F dual-injector fuel injection system is a key component to its performance; introduced in 2012, it was the world’s first to be featured on a production motocross bike. Unlike a standard digital fuel injection that uses one injector downstream of the throttle valve, the KX250F system uses a second, upstream injector located close to the airbox. The downstream injector—redesigned for 2017—is used to help ensure smooth, instant response featuring a finer atomization with more holes in the injector itself. The downstream injector creates that stronger low-to-mid range power and quick throttle response, while the upstream injector is charged with providing power.

As rpm and throttle position increase, primary operation switches from the downstream injector to the upstream injector, depending on whether in a low (1st, 2nd) or high (3rd, 4th, 5th) gear, the transition is gradual or almost instantaneous. The upstream injector’s greater distance from the combustion chamber gives the fuel particles and intake air more time to mix, as well as allowing the mixture to cool before entering the combustion chamber, both of which contribute to more efficient filling, and ultimately more power.

The 2017 model also features revised ECU settings, along with a new exhaust system. The exhaust header pipe is skinnier and shorter, resulting in improved performance.


Lightweight ECU, with revised settings
Three engine maps (standard, hard, soft) contained in the ECU
Optional KX FI Calibration Kit (Handheld) requires no tools, laptop or battery

The lightweight ECU of the KX250F motorcycle was designed specifically to withstand the rigors of motocross racing, while still providing a wide variety of tuning. The Kawasaki KX250F provides three engine maps that come pre-loaded into the motorcycle’s ECU that are easily accessible through the DFI® coupling plug. These three color-coded couplers are designed to tune for hard, medium or soft track surfaces, and allow riders to find the perfect power delivery for a particular terrain.

Using the optional KX FI Calibration Kit (Handheld), sold separately as a Kawasaki Genuine Accessory, a rider can store and select from up to seven separate engine maps. The kit includes a portable handheld calibration tool, which enables riders to make changes to the engine maps without the need of a PC, laptop or battery, making it easy to tune at the track. It plugs in thanks to an additional harness not included in the kit.

New Swingarm design with improved linkage ratio
Lighter weight and more rigid frame design
6mm narrower frame design
Showa 48mm Separate Function Front Forks (SFF Type 2)

Changes for the KX250F start at the frame, with a newly redesigned, lighter aluminum perimeter with a new front downtube and 3mm narrower main beams, for an overall reduction width of 6 mm. The frame rigidity has been optimized to obtain improved front end feel.
Up front you’ll find Showa 48mm Separate Function Front Forks (SFF Type 2) with works-style internal construction that locates its damping assembly in the left fork tube and a spring in the right. The Separate Function Front Fork construction contributes to a planted feel at the front, superb damping performance and ride comfort with greater bottoming resistance. It also has excellent stability when on the brakes or when landing jumps. For 2017, revised settings contribute to greater stability over braking bumps and through corners.
The Uni-Trak® rear suspension with Showa shock now features revised valve settings and linkage ratios, contributing to improved ride feel and traction and increased rear-end feedback. A lighter shock spring this year means a weight savings, and the lower rate contributes to the reduced pitching effect over braking bumps. The rear shock linkage mounts are below the swingarm to maximize wheel travel and the new linkage geometry increases cornering stability. Dual compression with high and low speed adjustability offers a wide range of tuning options. Self-lubricating alumite coating on the inner shock body improves wear resistance and shock action.

Easier for the rider to change position while riding
Integrated bodywork for seamless rider interface
Aggressive KX body work and in-mold graphics

The all-new minimalist bodywork includes slimmer shrouds, thanks to the revised radiators and their new orientation. The KX250F now features a new flatter and larger capacity fuel tank, along with a new flatter seat with reinforcing ribs. The combination of the new tank and seat aid in a more seamless design, which also makes it easy for riders to move around on top of the bike.
Aggressive all-new bodywork, which includes front and rear fenders, number plate and fork guards, makes the bike look more compact and is complemented by factory-style design and Kawasaki’s first in-mold graphics on the radiator shrouds. Black Excel rims, black fork guards, and green highlights help create a distinctive Kawasaki identity.
Returning this year are ERGO-FIT™ adjustable handlebars and footpegs to better suit riding styles and different rider statures. The handlebars have four position options and the footpegs have two placements available.


For pro riders and amateur riders alike, the KX Launch Control is a major advantage in getting out of the starting gate straight and fast. Launch Control Mode has the greatest effect within the first few seconds of releasing the clutch off the start.

The KX250F features a Launch Control system that, with the simple press of a button, allows riders to activate a separate engine map designed to assist starting in certain conditions. The Launch Control Mode map retards ignition timing, allowing tires to gain grip in low-traction situations, and allowing riders to focus on their lines. Launch Control remains active through first and second gear, until the rider shifts into third gear, and then it returns to normal engine timing.

Even for top-level riders, controlling the hard-hitting power of a KX250F motocrosser off the start requires a high degree of throttle control and clutch finesse. By optimizing this power, Launch Control Mode helps riders maximize traction, increasing the chance of getting a good start.

Contributing to the racing components found throughout the KX250F are the brakes, with 270mm petal-style disc brakes in the front. These brakes deliver strong braking force and superb control. The petal style discs contribute to both sporty looks and a high-quality appearance. Rear caliper guard protects the caliper from damage.
