Motorbike exhaust RS-4

For the 2024 version, Yoshimura has revised the RS-4 for the new YZ250F. By adding 1% more maximum power and 1.2% more maximum torque, the RS-4 tip is an excellent option for increasing power. 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.
