Yoshimura RS-9T Enduro Stainless Full Exhaust with Aluminum Muffler | Honda CRF125F / CRF125F Big Wheel 2019-2025 | Spark Arrester Installed

The Yoshimura RS-9T Enduro Stainless Full Exhaust System is a complete header-and-canister exhaust for the Honda CRF125F, built with a stainless steel header, an aluminum RS-9T muffler with a carbon fiber end cap, and a spark arrester installed from the factory — making it trail-ready in all 50 states out of the box.

The Enduro Series takes an approach opposite to a race system: the muffler carries more internal volume than stock, not less, which lowers the overall dB reading rather than raising it. On a CRF125F — a trail bike often ridden by younger or newer riders, frequently in shared riding areas and campgrounds — a quieter, better-flowing exhaust is genuinely more useful than a loud one.

The installed spark arrester is what makes it usable straight away. Public riding areas, national forest routes and OHV parks require an approved arrester, and it is checked at the gate; most performance exhausts arrive without one and need a separate insert purchase before the bike can legally turn a wheel on public land.
