Yamaha WR 250 F Camshaft - Hot Cams - Stage 2 - `15-`17. A direct-fit Stage 2 exhaust camshaft developed by Hot Cams for improved performance on 2015-2017 WR250F models (also referenced for 2015-2016 YZ250FX applications).

This camshaft is dyno-proven in the USA and engineered using modern valvetrain simulation to deliver measurable gains without complex modifications. CNC-machined from 8620 billet, case-hardened steel, the lobe profiles are produced for precise fit and consistent durability. Stage 2 provides a tuned profile aimed at stronger mid-to-top-end response while remaining a relatively simple install for experienced technicians. No core exchange is required, and Hot Cams offers multiple stages to match different build goals.
