 | | Grand Prix motorcycles are almost completely unrestricted in their design, except for minimum weight and engine capacity requirements. |
 | | The motorcycles, particularly the 500cc machines, are made out of exotic and expensive materials, including titanium and carbon fibre, and are equipped with sophisticated electronics including telemetry, engine management, and traction control, though most machines still use carburettors because fuel injection's throttle control isn't precise enough for the riders. |
 | | While the 500cc motorcycles are raced only at World Championship level, 125cc and 250cc bikes are available at relatively reasonable cost for purchase (the 125cc bikes are available for about the same as a small car), and are thus raced in national championships around the world. |
