Getting the tube diameter and length exactly right, then letting the RS-12 do the job it was designed for, brought more power and torque across the whole range. It was not easy, but the results are clear: maximum horsepower rises by 8% and maximum torque by an impressive 13%.\u003c\/p\u003e\u003cp\u003eThe biggest improvements come in the lower and mid rpm range, and they arrive without upsetting the handling of the new YZ chassis.
