The Pro Circuit R-304 Silencer is a compact, high-performance exhaust component designed for 2002 through 2011 Yamaha YZ85 models. Manufacturer part number SY93080-RE, this silencer is engineered to deliver strong performance gains for closed-course racing applications. Its compact construction supports responsive race-oriented performance while maintaining compatibility with the specified Yamaha YZ85 fitment.
The R-304 uses hex-head screws to secure the inlet cap, allowing the cap to be removed quickly when service or repacking is required. This design makes routine maintenance more efficient and helps reduce downtime between rides or race events. The silencer must be used with the appropriate Pro Circuit pipe or the stock pipe, as applicable to the installation configuration.
