The Pro Circuit R-304 Silencer, manufacturer part number SH00250-RE and vendor part number 792-0203R, is designed for closed-course racing applications on select Honda motocross motorcycles. Its compact design helps deliver strong performance gains while maintaining the race-focused construction expected from Pro Circuit exhaust components. This silencer fits 2000–2001 Honda CR125R and 2000–2001 Honda CR250R models.
The R-304 uses hex-head screws to secure the inlet cap, allowing the cap to be removed quickly when repacking is required. This service-friendly design helps simplify routine maintenance and reduces downtime between race sessions. The silencer is intended for use with the appropriate Pro Circuit pipe and must be matched with a stock pipe as specified for the application. Verify the motorcycle model, year, and pipe configuration before installation.
Built for closed-course racing only, the Pro Circuit R-304 Silencer is intended for riders seeking responsive exhaust performance and convenient serviceability. It is not designed for street use or applications requiring compliant noise emissions. Professional installation is recommended to ensure proper alignment, secure fastener installation, and correct fitment with the motorcycle's existing exhaust system.
