Moto3 Regulations Released by stafftastic Thursday, October 06, 2011
The death of the two-stroke hit home even more Thursday, Oct. 6, when the FIM issued technical regulations for the new Moto3 class that's replacing the 125cc category in the World Championship starting in 2012.
Some of the key highlights:
Engine:
250cc, four-stroke only. Single cylinder only. No turbocharging or supercharging. Crankshaft limited to 14,000 rpm. No pneumatic or hydraulic valve systems. No variable valve timing or valve lift systems permitted. The maximum price of the engine is 12,000 Euros, including the throttle body, injectors and a complete transmission. Any team competing in the race can buy the engine used in that race by another team for 12,000 Euros. (The "claimer" rule) Each engine manufacturer must supply sufficient engines and spare parts for 15 riders per season, if requested. The minimum will be eight riders for manufacturers entering the championship for the first time. A maximum of eight engines can be used per rider for the entire season. A rebuilt engine is counted as new.
Inlet, Fuel System and Lubricant:
The throttle must be controlled exclusively by mechanical means (i.e., cable) that is operated by the rider only. Maximum of two fuel injectors and two independent fuel injector drivers.
Transmission:
Maximum of six gearbox speeds, with a maximum of two possible gear ratios for each gearbox speed and two possible rations for the primary driver gear. Teams must declare the two ratios chosen for each gear at the start of the season, with only those ratios used all season. Seamless-shift transmissions prohibited.
Ignition, Electronics and Data Logging
Only ECU's approved by the series organizer are allowed, and they cannot be modified. The official ECU will include an engine rpm limiter and an inboard data logger. No other data-logging devices can be used.
Chassis
Minimum total weight of the motorcycle and rider is 148 kg (326.3 pounds). Brake discs must be made from ferrous materials (steel).
Materials and Construction
Camshafts, crankshafts and piston pins must be made from ferrous materials (iron, steel). Engine crankcases, cylinder blocks and cylinder heads must be made from cast aluminum alloy. Pistons must be made from an aluminum alloy. Connecting rods, valves and valve springs must be made from ferrous- or titanium-based alloys.
