Yoshimura RS-12 Full Exhaust System for Yamaha Motorcycles

Yoshimura RS-12 Full Exhaust System for Yamaha Dirt Bikes

Forged through 24 months of factory racing R&D, the RS-12 redefines performance with its radical asymmetrical silhouette. Engineered specifically for Yamaha off-road machines, this exhaust delivers tangible track advantages:

Track-Dominating Innovation
– Racing-Bred Power Gains: Asymmetry maximizes muffler volume—boosting torque across RPMs while optimizing sound suppression. Ideal for motocross circuits or aggressive trail riding.
– Weight Centralization: Tapered inlet shifts mass forward, enhancing bike balance during jumps and cornering without sacrificing horsepower.
– Critical Clearance: Aggressive profile creates extra room for oversized tires and brake calipers—vital when tackling rocky terrain or muddy trails.

Durability Meets Simplicity
– Our proprietary matte carbon end cap features an inner-mount design (not industry-standard sandwich mounts) to withstand crashes and simplify repacking—no disassembly headaches mid-season.
– Patent-pending PTF insert ring lets riders swap spark arrestors or dB reducers tool-free in seconds—perfect for noise-restricted parks or competition days.
