The Pro Circuit R-304 Silencer is designed for Yamaha YZ125 two-stroke motorcycles from 2002 through 2011. Its compact construction is engineered to deliver strong performance gains for closed-course racing applications. The aggressive race-oriented output makes this silencer intended for track and competition use only.
Hex-head screws secure the inlet cap, allowing the cap to be removed quickly for convenient repacking and routine maintenance. This serviceable design helps reduce downtime between races while supporting consistent silencer performance. The R-304 must be used with the appropriate Pro Circuit pipe or stock pipe for proper fitment and system compatibility.
Fitment includes 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, and 2011 Yamaha YZ125 models. Pro Circuit is the manufacturer and brand, and SY02125-RE is the manufacturer and vendor part number. Verify the motorcycle model year and exhaust configuration before installation.
