Introducing the OSSPEED R21 series - the pinnacle in the motor car category !

The OS SPEED R21 series won the World Championship held in the United States. Most of the "R2105" parts have been redesigned with more victories in mind.

To increase torque on high-grip surfaces, a newly designed 9-hole bushing was used. The traditional DLC-coated OS SPEED crankshaft provides linear power from low to high by changing the counterweight. The outer head has been given a mirror finish.
