Hotcams exhaust - Level 1 CamshaftRef : HO00025A / 1006459

HOT CAMS Stage 1 exhaust camshaft designed for Yamaha WRF/YZF450 (manufacturer part number: 4044-1E). Developed and tested on test benches and by competition teams, this cam profile offers a lightweight tuning solution for motocross and quad machines.

• Stage 1: increases torque and power without any further modifications needed — ideal for a small plug-and-play upgrade.
• Stage 2: reserved for heavier modifications, requires additional changes (high compression pistons, carburettor, etc.).
• Stage 3: developed for Supermoto or displacement increase (to be fitted with original springs).

The kit includes two complete sets of shims to allow for precise valve timing adjustment. Installation is recommended by a qualified mechanic with the appropriate tools — the operation requires precision and timing control to fully benefit from the cam profile.

• YAMAHA WR 450 F (DJ03) — 2015
