We have developed O.S. SPEED R21 SHIMO edition collaborated with TAKAAKI SHIMO, a multiple podium winner of the IFMAR 1/8 Racing World Championship. It is a 7-port engine with a new cylinder liner, which has extra holes to reduce overheating. The cooling head and 8.5mm carburettor restrictor are anodized in the special colour; champagne gold. The crankshaft is modified to meet his preference, smooth power transition from bottom to the top speed.
