1.9 Valve timing system drive must be by one chain. An intermediate drive gear which rotates on only one axle or rotation centre is allowed in the system (refer to ANNEX1 for some examples of permitted systems).
1.10 Variable valve timing and/or variable valve lift systems are not permitted.
Engine Supply
1.11 The engine is defined as the complete engine including intake system (throttle body, injectors), and one complete transmission.
1.12 The maximum price of the engine must not exceed 12,000 Euros. No optional parts or service contracts may be used to circumvent this price limit.
1.13 Each engine manufacturer must undertake to supply sufficient engines and spare parts to supply 15 riders per season, if requested.
1.14 Each engine manufacturer must submit a spare parts price and lead-time list for the season for approval by the Organiser, and may not charge more than these published prices. Approval is based on the prices and lead-times being in line with current market norms for these parts and technologies.
1.15 In the event of engine updates or upgraded parts being developed, these must be made available to all customers at the same time, and respecting the price limits described in Art. 1.14.
1.16 The official ECU start-up procedure is to ensure manufacturers will be supplied with the official ECU with an initial map to suit their engine in time for the first official Moto3 tests. The initial map is intended for safe and trouble-free engine function, and not maximum performance. Performance mapping is the responsibility of the engine manufacturer or the Team.
For an engine to be eligible for the Moto3 class, one of the following two options for the ECU start-up procedure must be followed:
1. Manufacturers will be guaranteed supply of the official ECU with initial maps to suit their engine in time for the first official Moto3 tests provided that, by October 15th of the preceding year:
a) the Moto3 Engine Manufacturer Entry Form is completed and submitted to the organisers (see ANNEX 3),
b) two complete and working engines (including throttle body, idle bypass actuator, transmission, sensors, spark plugs, complete wiring harness with ECU connector) and one complete airbox, cooling system, and exhaust are delivered to the organisers for mapping tests (engines will be returned in January of the following year at the latest),
c) a deposit of 10,000 Euros is lodged with the organisers.
or
2. Manufacturers can make an agreement with the ECU supplier to carry out their own initial mapping, with the following conditions:
a) the Moto3 Engine Manufacturer Entry Form is completed and submitted to the organisers (see ANNEX 3).
b) the ECU will be delivered to the manufacturer in the first instance only by the ECU supplier, and the ECU supplier representative must be present to initiate setup of the mapping process.
c) the organisers and the ECU supplier provide no guarantee of any completion date for the mapping process.
d) there is no set deadline for this second option, but option 1 takes precedence and requests for option 2 made before Oct. 15th, 2011 will be processed at a time determined by the ECU supplier.
2. Inlet & Fuel System
2.1 Variable-length inlet tract systems are not permitted.
2.2 Only one throttle control valve is permitted, which must be controlled exclusively by mechanical means (eg. cable) operated by the rider only. No other moving devices (except injectors) are permitted in the inlet tract before the engine intake valve. No interruption of the mechanical connection between the rider’s input and the throttle is allowed.
Idle speed (including engine braking) adjustment by means of an air bypass system, controlled by the ECU is allowed (see also 5.4).*

4. Transmission
4.1 A maximum of 6 gearbox speeds is permitted.
4.2 A maximum of 2 possible gear ratios for each gearbox speed, and 2 possible ratios for the primary drive gear is permitted. Teams will be required to declare the two gearbox ratios chosen for each gear at the beginning of the season, and only these ratios may be used during the entire season.
The alternate gearbox ratios and primary gears must have the same list price and lead-times as the original supplied gearbox (see Art. 1.11 to 1.15).
4.3 Electro-mechanical or electro-hydraulic clutch actuating systems are not permitted.
5. Ignition, Electronics & Data-Logging
5.1 Only the ignition/fuel injection control units (ECU) approved by the series Organiser are allowed.
This ECU must remain unmodified in hardware and software, as delivered by the Organiser. The only permitted changes are the setting (tuning) options included in the software.
The Technical Director may require the team to change the ECU on any machine for another standard one at any time.
5.2 This official ECU will include an engine rpm limiter.
5.3 This official ECU will include an inboard data logger, and no other additional data loggers may be used.
5.4 Recommended engine management and electronics features:
- dashboard Dell’Orto part # 16001, see ANNEX 4,
- idle speed control stepper motor (ref. 2.2) Dell’Orto part # 17258, see ANNEX 4,
- two timing options:
1. only crankshaft pickup: the crankshaft timing pattern being the “n-2” type, where “n” can be from 12 to 30 (for optimum performance it is advised that the first tooth “after” the missing ones is corresponding to the top dead centre), or
2. crankshaft and camshaft pickups: the crankshaft timing wheel having from 12 to 30 teeth and the camshaft timing pattern being 1 single tooth.
The above mentioned features are guaranteed to work properly, different choices and the relevant development costs and timings must be agreed separately with the ECU manufacturer.

9.2 Number of engines: a maximum of 8 engines per rider may be used during all Grand Prix race events comprising the season. A rebuilt engine will be counted as a new engine (see Art. 9.4).
9.3 Teams will be required to register engines at Technical Control on the day before the first practice at each event. Such registered engines will be sealed and seals may not be removed except under supervision of the Technical Director and staff. Only sealed and registered engines may be used on track at Grand Prix race events. An engine presented for Technical Control or used on track without intact security seals will be counted as a new engine.
9.4 1) Engine seals: The engines will be sealed by means of wiring and identification tabs and/or other systems, so that major components (including but not limited to: crankshaft and it’s bearings, conrod and it’s bearings, piston, piston rings and piston pin, valves and their springs, camshafts) can not be replaced. Sealing positions must be approved by the Technical Director so that:
a) the timing system is accessible for the sole purpose of adjusting the valve clearance (e.g. the cylinder head cover/cam cover can be removed from the cylinder head), but valve shims must be the only parts that can be replaced (or valve clearance adjusters can be reached) without breaking the security seals. If the engine design does not allow such adjustments without removing security seals, then valve shims cannot be replaced (e.g. it must not be possible to remove camshafts and rocker arms, if any, without breaking the seals).
b) the cylinder head and the cylinder (if any) cannot be removed from the engine (e.g. the cylinder head is wired to the cylinder and the cylinder is wired to the engine crankcase),
c) the crankcase cannot be opened (e.g. the crankcase halves are wired together).
2) All parts that are accessible without removing the security seals may be replaced. Breaking or removing the security seals or wiring without supervision by the Technical Director or staff will be deemed to be “engine rebuilding” and engines with broken, tampered with or missing security seals will be treated as a new engine in the allocation.
3) As an exception to the above, it will be possible for the 2012 season to break the seals if all of the following conditions apply:
a) under supervision of the Technical Director and staff (details TBA),
b) with the sole purpose of:
I.
changing the gearbox ratios (see Art. 4.2), on an engine design where seals need to be broken for internal gearbox access.
II.
replacing the timing chain, on an engine design where seals need to be broken to access the timing chain.
c) once per race event per rider at a time and place determined by the Technical Director (details TBA), i.e. the operations mentioned in b) I. and b) II. must be performed at the same time, if both are required.
9.5 Apart from the above regulations, all other construction criteria, dimensions and specifications are as per the FIM Grand Prix Regulations.
