Almost all the parts including the crank case have been re-tuned from O.S.Speed 12XZ specIII which has won at Japanese TC Nats in 2013. We again precisely questioned ourselves for "what is the specifications for win?". Our answer is "longer stroke." As the result, not only the torque feeling at low to middle range is improved but better gas mileage are realized. The brand new O.S.Speed T1201 also loaded with DLC coated crank shaft and other cylinder/piston, inner head, carb are accurately tuned again too. The lower height outer head contributes for lower center of gravity and better cooling characteristics. Bearing: F-Steel ball, R-Ceramic ball
