New Moto2 specs revealed
MotoGP organisers have revealed details of the new ‘Moto2′ Championship which will replace the 250cc class from 2011.
The decision to replace the two-stroke 250cc championship with a new, four-stroke championship was confirmed in June amid some controversy but the FIM have nevertheless taken the decision to announce details of the new 600cc competition.
The stand-out regulations are that only four-stroke, non-turbo or supercharged engines will be permitted, but they will be able to run two, three or four-cylinders. These will be rev-limited and have different weight minimums to keep them on a par with one another.
Another interesting aspect to the regulations is that teams will be able to buy engines from rival teams for the fixed price of €20,000.
The regulations state that “the engine (excluding exhaust, throttle bodies and ECU) used in a race is available to be purchased by another competitor in the same race for a fixed price of €20,000 (Euro). Such purchase request must be made in writing to Race Direction within the protest period that is within 60 minutes after the official end of the race.
“The transaction and delivery will be completed immediately at the end of the 60 minute protest period and will be underwritten by IRTA. Teams refusing to sell when presented with a valid request will be disqualified.”
With the emphasis very much on cost-cutting, Moto2 will use standard options in terms of engine and electronics, but will continue the 250cc series´ pursuit of developmental excellence with the running of a prototype chassis -free from limitation. No production bike parts will be permitted for the frame, swing arm, fuel tank, seat and cowling, meaning that these aspects of the machine will also be left to the manufacturer and designers´ discretion. Carbon brakes like those used in MotoGP will however be banned in the 600cc class.
The technical specifications in full are:
ENGINE
4-stroke engines only.
Engine capacity: maximum 600cc.
4 cylinders maximum.
No oval pistons.
Engines must be normally aspirated. No turbo-charging, no super-charging.
Engine speed limited to maximum: 16,000 rpm. 4-cylinder engines 15,500 rpm. 3-cylinder engines 15,000 rpm. 2-cylinder engines An electronic system supplied by the Organisers will be permanently attached to monitor and control engine speed.
Pneumatic valve operation is not permitted.
Inlet and Exhaust valves must be of conventional type (reciprocating poppet valves). Variable valve timing or variable valve lift systems are not permitted.
Only wet-sump type engine lubrication systems are permitted.
Minimum weight of complete engine with throttle body, dry:
53 kg 4-cylinder
50 kg 3-cylinder
47 kg 2 cylinder
INLET AND FUEL SYSTEM
Variable-length inlet tract systems are not permitted.
Only one throttle control valve per cylinder is permitted. No other moving devices are permitted in the inlet tract before the engine intake valve.
Throttle bodies will have a maximum internal diameter (must be perfectly circle except for the area of dent or groove to allow the injector to come out) at engine side out-let of:
42 mm for 4-cylinder
48 mm for 3-cylinder
59 mm for 2-cylinder
Fuel injectors will be restricted to a defined type (tba, based on cost).
EXHAUST
Variable length exhaust systems are not permitted.
Noise limit will be a maximum of 120 dB/A, measured in a static test.
GEARBOX
A maximum of 6 gearbox speeds is permitted.
A maximum of 3 alternate gear ratios for each gearbox speed, and 2 alternate ratios for the primary drive gear is permitted. Teams will be required to declare the gearbox ratios for each gear used at the beginning of the season.
Electro-mechanical or electro-hydraulic clutch actuating systems are not permitted.
IGNITION AND ELECTRONICS
Data logger system will be supplied by the series organiser.
Only the ECU/fuel injection control units supplied by the series organiser are allowed to be fitted to the motorcycle. Electronic control units include the timing transponder, engine RPM control, and datalogger systems. No other electronic control or datalogging systems will be allowed on the motorcycle.
The price of ECU unit made by each engine manufacturer must be equal to or less than JPY75,000 (about Euro650).
CHASSIS
Chassis will be a prototype, the design and construction of which is free within the constraints of the FIM Grand Prix Technical Regulations. The frame, swing-arm, fuel tank, seat and cowling are forbidden to use from a non-prototype as series production road-going motorcycle.~
Minimum Total Weigh
135kg for 4-cylinder
130kg for 3-cylinder
125kg for 2-cylinder
No carbon brake discs.
TYRES
The number of slick tyres allocated to each rider per event will be controlled.
MATERIALS
The following components must be made from iron-based alloys:
Valve springs, camshafts, crankshafts, connecting rods, piston pins, brake discs.
Engine crankcases and cylinder heads must be made from cast aluminium alloys.
Pistons must be made from an aluminium alloy.
GENERAL
Number of machines: the team can scrutineer only one motorcycle per rider.
Number of engines: a maximum of 2 complete engines per rider is permitted at any event. Teams will be required to register engine serial numbers at Technical Control on the day before the first practice.
The engine (excluding exhaust, throttle bodies and ECU) used in a race is available to be purchased by another competitor in the same race for a fixed price of €20,000 (Euro). Such purchase request must be made in writing to Race Direction within the protest period, that is within 60 minutes after the official end of the race. The transaction and delivery will be completed immediately at the end of the 60-minute protest period and will be underwritten by IRTA. Teams refusing to sell when presented with a valid request will be disqualified.
