These motorcycles are very similar to the original and therefore to the production model. Modifications are limited, especially relating to the mapping of the electronic fuel injection units. The engine must remain in its original configuration. Reinforcing the clutch and changing the air filter, silencer, internal parts of the forks, rear suspension unit, countershaft sprocket and rear wheel sprocket are allowed, as is mounting a steering damper and a quick-fill device for refuelling. The original wheel fasteners shall be used, therefore good strategy and coordination will be required when changing the wheels on pit stops.
