Rizla Suzuki Girl, Italian MotoGP 2007

• Moto2 class
Moto2 is the new 600cc 4-stroke class to replace 250cc 2-stroke class. Engines are produced by Honda; tyres by Dunlop and electronics will be limited and supplied only by FIM sanctioned producers with max cost set at 650 EUR. Carbon-fibre brakes will be banned and only steel brakes will be allowed. However, there will be no chassis limitations. From 2010 onwards, only 600 cc four-stroke Moto2 machines are allowed.
• MotoGP class
New specifications for each racing class are formed as the FIM sees fit. At the beginning of the new MotoGP era in 2002, 500cc two-stroke or 990cc four-stroke bikes were specified to race. The enormous power advantage of the larger displacement four-stroke engine over the two-stroke eliminated all two-strokes from competition; the following season no two-stroke bikes were racing. In 2007 the maximum engine capacity was reduced to 800cc without reducing the existing weight restrictions.
