O.S.SPEED R21GT II 1DT00

While inheriting the smooth feeling and good fuel efficiency of the previous model O.S.SPEED R21GT, which was well received in the European market, the home of GT cars, the power feeling in the medium and low speed ranges has been improved by revising the counterbalance of the crankshaft. In addition, the newly designed inner head improves idling performance, and an inner head O-ring is used to reduce vibration and improve dust resistance. The outer head has been made lighter, and has evolved into the O.S.SPEED R21GT II with attention to the detail.
