Yamaha WR 250 F (CG 22) [2005] - Camshaft inlet - Stage 2 Yamaha YZF/WRF 250

HOT CAMS Stage 2 intake camshaft for Yamaha WR 250 F

This intake camshaft from HOT CAMS is designed as a Stage 2 version for further engine tuning. The brand's camshafts were developed on test benches and tested by leading teams. Within the three-stage HOT-CAMS concept, Stage 2 is aimed at engine structures where additional changes are planned.

Function and coordination

In order for the Stage 2 camshaft to develop its potential, further adjustments are required. HOT CAMS cites high-compression pistons and a larger carburettor as examples. The camshaft is therefore suitable for specifically tailored engine projects and not as an isolated change without taking the rest of the engine configuration into account.

• Intake camshaft in Stage 2 design
• Developed for further engine tuning
• Developed on test benches and tested in use by leading teams
• Two sets of valve shims included for adjustment

Vehicle assignment

The camshaft is expressly the Yamaha WR 250 F (CG 22), built in 2005, assigned. When selecting, the model name, type identification and year of manufacture should completely match the motorcycle.

Factual assembly instructions

HOT CAMS recommends having the necessary preparation and assembly work carried out by qualified specialists using suitable tools. This is particularly relevant as the Stage 2 design is combined with further changes to the engine and requires a coordinated configuration.
