YOSHIMURA RS-12 Signature Series Full Exhaust System

The Yoshimura RS-12 full exhaust system was specifically developed for the Triumph TF450, delivering noticeable performance gains and the signature Yoshimura racing sound. The system combines a durable stainless steel header with a lightweight aluminum muffler featuring a carbon fiber end cap, improving exhaust flow and enhancing power delivery throughout the rev range.

Compared to the stock exhaust, the RS-12 provides up to +11.3% horsepower and +10.8% torque at 5,000 rpm, resulting in stronger acceleration and improved throttle response—ideal for motocross and off-road riding.
