Difference between revisions of "Motorcycle racing"

Supermoto is a racing category that is a crossover between road-racing and motocross. The motorcycles are mainly motocross types with road-racing tyres. The racetrack is a mixture of road and dirt courses (in different proportions) and can take place either on closed circuits or in temporary venues (such as urban locations).

Indoor races consist of either a polished concrete floor with coke syrup or other media sprayed or mopped onto the concrete for traction for the tyres of the motorcycles, or on dirt that has been moistened and hard packed, or left loose (often called a cushion). Motorcycles race on an oval track, or over a single jump with a right hand turn called a TT track. Similar to size of the Arenacross Arenas or sometimes smaller the riders must have accurate throttle control to negotiate these tight Indoor Race Tracks.{{Clear}}

In the U.S., Short Track and TT races are part of a specific discipline labelled "Dirttrack" or sometimes "Flattrack" (also called Flat Track). However the AMA Sanction rule books refer to this discipline as Dirttrack racing.  Whether Short Track or TT, traction is what defines a dirttrack race. The bikes cannot use "knobbies", they must use "Class C" tires which look a lot like street tires. On a Short Track course, the track is an oval, all turns to the left only, and only a rear brake is allowed. On the TT courses, as mentioned above, there must be at least one right hand turn a jump is optional, a front brake is allowed, but the same "Class C" tires are required. Although not mandated, most flattrack racers wear a steel "shoe" on the left boot which is actually a fitted steel sole that straps onto the left boot. This steel shoe lets the rider lean the bike to the left while sliding through the corners.
