The Pro Circuit 304 Silencer, manufacturer part number SY02125-SE and vendor part number 792-5203, is designed for most two-stroke applications and fits Yamaha YZ125 models from 2002 through 2011. Its slightly longer body helps provide reduced noise output compared with the Pro Circuit R-304 model, making it a practical choice for riders seeking dependable performance with a more controlled exhaust note.
Constructed with a brushed aluminum body, stainless steel inlet tube, and stainless steel end cap, this silencer combines durable materials with a clean, high-quality finish. The design supports consistent exhaust performance while providing the durability required for motocross and off-road riding. The 304 Silencer must be used with a Pro Circuit pipe as specified for the application.
Fitment includes the 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, and 2011 Yamaha YZ125. Confirm your motorcycle model year and exhaust configuration before installation.
