The Factory-R maintains and extends the typical features of the Factory release. These features allow you to keep the engine weight low: use of carbon components, titanium screws, fully machined components. Important work was done on the engine to increase the power output; a lot of work has been made on engine timing and on the air intake, with a new carburetor that has a larger diameter.

Includes a Carbon Fiber Airbox and Carbon Fiber Cooling Shroud.
