Product details
Yoshimura CRF450R/RX 2021-2024 / CRF450R-S 2023-2024 RS-12 Stainless Full Exhaust, W/ Stainless Muffler
The #1 exhaust in Supercross and Motocross that powered Chase Sexton to the 2023 450 Supercross title, and Jett Lawrence to the 2023 450 Motocross SMX title and perfect season!
In our never ending pursuit to craft the very best exhaust system, Yoshimura introduces the latest RS-12 stainless steel system for the Honda CRF450R/RX.
Why did we go through the task of introducing a whole new system for the CRF450? With the latest engine spec, our engineers wanted to get the best most usable power from this new model. This new system incorporates a one-piece stainless steel cast manifold featuring an integrated bolt flange surface that is 3x stronger than conventional designs.
This new system has been developed with - and is the closest thing to what 5x World Champion Tim Gajser, Chase Sexton, Jett Lawrence have been using to grab holeshots and win championships. By increasing the resonator in the RS-12 muffler by 50cc (a 14% increase) and adding a second resonator to the header, our engineers were able to unlock some insane usable power from this new and improved system.
The new RS-12 system adds 5% max hp and 6.5% max torque to the new engine spec with its smaller throttle body and different ECU settings.
What does this translate to?
- Easier power delivery
- Smoother frontside torque
- Allows the rider to ride in an higher gear, thus freeing up suspension.
- Less rider fatigue
