Exhaust no. 1 in Supercross and Motocross leading Chase Sexton to the 2023 450 Supercross title and Jett Lawrence to the 2023 450 Motocross SMX title!

In the continuous quest to make the best exhaust system, Yoshimura introduces the latest RS-12 stainless steel system for the Honda CRF450

This new system was developed with 5 time world champion Tim Gajser, Chase Sexton and Jett Lawrence who used it to get holeshots and win championships. By increasing the resonator in the RS-12 muffler by 50cc and adding a second to the manifold, engineers were able to unlock insane usable power from this new and improved system.

The RS-12 adds 5% maximum horsepower and 6.5% maximum torque to new engine specifications

Easier power delivery

Smoother front torque

It allows the rider to ride in a higher gear, thus freeing up the suspension.

Less rider fatigue

Technical features:

- Developed thanks to the data collected in over 24 months of international competitions

- More aggressive and sporty profile

- Designed to maximize the sound produced by the terminal

- Provides maximum power at all revs

Warning: When installing the complete exhaust system, it may be necessary to remap the ECU.
