Yamaha YZ 450 FX Exhaust Camshaft - Hot Cams - Stage 1 ('16-'19) is a performance-oriented exhaust camshaft developed for Yamaha four-stroke off-road models. It provides a targeted power improvement while maintaining reliability for trail and race use.

This Hot Cams Stage 1 exhaust camshaft is dyno-proven in the USA and engineered using advanced valvetrain software to refine timing and lift for improved midrange and top-end response. CNC-machined from 8620 billet, case-hardened steel, the cam offers precise lobe profiles and a consistent fit. The Stage 1 profile is designed to deliver a modest, reliable gain—typically in the 5–10% range—without requiring major supporting modifications. It’s available in multiple stages to match different tuning goals and does not require a core exchange.
