How it works
While other exhaust brands just carried over their Yamaha YZ250F offerings to include 2024 model, on the dyno and track, the new YZ told us there was more on the table. So our R&D team went to work to optimize the new Yamaha.
Revised for the 2024 is our RS-4 slip-on for the new YZ250F. Adding 1% max HP and 1.2% max torque, the RS-4 slip on is a great option for adding some power. RS-4 also has the ability to add a spark arrestor for off-road adventures.
Yoshimura's RS-4 system is proudly designed, developed and manufactured in Chino, California.

Size chart
We want everything to fit right . Take some quick measurements if you are unsure of your current clothes size. The most accurate measurements will be those you take in your underwear, applying the measuring tape directly to your body.
Please note that the information in this size chart is not specific to the manufacturer's products as we currently do not have the manufacturer's original size chart. The details in the size charts are not binding and are for guidance only. If something does not fit you, of course you can exchange the goods with us (see FAQ Exchange / Complaint).
