Features

YOSHIMURA RS-12 Signature Series — Manufacturer part number: 234840S320

Designed for motocross riders in search of a race-ready exhaust, the complete RS-12 line from Yoshimura US is the result of over two years of development and competitive testing. The silencer features an aggressive asymmetrical profile, engineered to maximize volume while facilitating mass centralization through a forward thrust of the assembly.

Finish: stainless steel header, aluminum silencer body, carbon end cap
Machined joints for precise fit and improved longevity
Yoshimura-designed carbon end cap: simplified maintenance and access to the dB killer
Installation designed for easy removal/installation of the spark arrestor and dB killer
Manufactured in the USA — circuit use only (not noise approved)

Suitable for the listed motocross machines and particularly favored on the Yamaha YZ 450 F (2023–2025), the RS-12 combines racing aesthetics with high-quality components. It is aimed at riders who want a track-ready exhaust with an aggressive look and competition-oriented technical details, without compromising access for routine maintenance operations.
