Yoshimura Motorcykeludstødning RS-4

For 2024, Yoshimura has revamped the RS-4 for the new YZ250F. By adding 1% more peak power and 1.2% more peak torque, the RS-4 tip is an excellent choice for boosting performance. The RS-4 also allows for the addition of a spark arrestor for off-road adventures.

The RS-4 system from Yoshimura is proudly designed, developed, and manufactured in Chino, California.
