The Grand Prix Commission, MotoGP’s ruling body met at Brno at the weekend and they finalized the demise of the two-strokeengine from Grand Prix Racing. It’s long rumoured that the Fédération Internationale de Motocyclisme (FIM) would phase out two-smokers. The new class will be officially called Moto3, with the first season to kick off in 2012.
The long era of the two-stroke engine comes to an end
In the Moto3 category there will be single-cylinder 250cc four-stroke engines with a maximum bore of 81mm that will have to last for at least three races and not cost more than €10.000. The new rules also specify that the new class will not use a spec engine and that manufacturers will have to supply at least fifteen riders with their engines. That means 6 engines per season for 15 riders equals 90 engines.
Two-stroke engines won't have long future in street bikes either
