Features:

While inheriting the smooth feeling and fuel economy of the previous O.S. SPEED R21GT model, which was well received in the European market, the home of GT cars, the crankshaft counterbalance has been reviewed to improve the power feeling in the mid-low speed range. The inner head has been newly designed to improve idling performance, and an O-ring has been adopted to reduce vibration and improve dustproofing. The outer head has been lightened and evolved into the O.S.SPEED R21GTII, which has been carefully designed in many areas. Also available is a combo set that includes a TB01 (EFRA2042) tuned silencer and MB01-70 manifold exhaust system.
