Product details
Yoshimura calls the RS-12 the number one exhaust in Supercross and Motocross. In 2023 it carried Chase Sexton to the 450 Supercross championship, while Jett Lawrence used it to win the 450 Motocross and SMX titles with a perfect season.
This latest titanium RS-12 system is made for the 2021-24 Honda CRF450R. Yoshimura built a whole new system because the newest engine spec gave its engineers the chance to extract the most usable power from the model.
It was developed alongside, and is the closest thing to, the exhausts used by 5x World Champion Tim Gajser, Chase Sexton and Jett Lawrence to take holeshots and win championships. The resonator in the RS-12 silencer has grown by 50cc (a 14% increase) and a second resonator has been added to the header, releasing a lot more usable power from the updated system.
What it means for you
- Power that is easier to use
- Smoother frontside torque
- You can ride a gear higher, which frees up the suspension
- Less fatigue for the rider
- Premium grade Japanese titanium tubing
- Adds 5% maximum horsepower and 6.5% maximum torque to the latest engine, which has a smaller throttle body and changed ECU settings
