YOSHIMURA RS-12 Signature Series Full System (manufacturer part number 231030S320): a performance-oriented exhaust for motocross, designed to reduce weight and optimise engine response without compromising on finish. The RS-12 system increases maximum power by 2.5% and maximum torque by 2.8% compared to the base version, and it is proudly designed, developed, and manufactured in Chino, California.

• Silencer stainless steel body with a matte carbon fibre end cap for a race look and improved thermal shock resistance.
• Header stainless steel for increased longevity and adaptation to off-road conditions.
• Asymmetrical profile of the silencer: optimised volume to control sound, clear the tyre/caliper space, and concentrate mass.
• Machined gaskets and PTF (Precision Taper Fit) ring facilitating adjustment, installation, and removal of sound inserts and spark arrestor.
• Homologation: FIM approved, compliant with competition requirements.

Designed for demanding riders, the RS-12 offers easy installation and maintenance thanks to its end cap and removable insert. Ideal for Yamaha YZ 250 F (2024-2026) and any motocross rider looking for a robust, high-performance part with a racing style signed by Yoshimura US.
