The 2025 Honda CRF450R has been unveiled, and when it comes to Honda Motocross Racing exhaust systems, no one comes close to Yoshimura's American R&D team.
The all-new CRF450R boasts a new chassis, airbox and ECU configuration. The Yoshimura engineering and development team worked hard with Team Honda HRC to squeeze every drop of performance out of the new 450. With our new complete RS-12 Signature Series system, we achieved a 2% peak HP increase over stock while the peak torque gain was 5%.
