An all-new engine has been designed for high-revving performance that delivers a linear engine response with more power and torque through the rpm range, increasing the rev limit by 700 rpm from the previous model. This was achieved through the adoption of a rocker arm with finger follower system derived from Yamaha’s SuperSport YZF-R1, and intake refinements that allow for increased airflow and higher revs. Despite the increase in power, revisions to the air cleaner box and exhaust systems help make the 2027 YZ250F noise-compliant, meeting FIM/AMA regulations with a tuned exhaust note that is both more pleasing and comfortable to the rider.
