Choice of Champion Champagne gold to glory.

OSSPEED support driver Introducing OSSPEED R21 SHIMO EDITION 2 created by feeding back the know-how of Mr. Akira Shimotaka. The exterior uses a special color champagne gold outer head and reducer. Based on the R21 series, a newly designed crankshaft that emphasizes connection from low speed to high speed has been adopted, and the cylinder liner has been subjected to new processing that can reduce seizure on a 7-port base, achieving performance that can win the race. A set of TR02 (EFRA2165) + MR03-WC that maximizes the power of the engine.
