Developed on test benches and tested by leading teams, HOT CAMS offers three levels of products.

• Stage 1 (Level 1): increases torque and power without further modification. Ideal for small preparations.
• Stage 2 (Level 2): more suited to heavy preparation, it requires further modifications to deliver its benefits, such as high-compression pistons and a large carburetor.
• Stage 3 (Level 3): specially developed for Supermotard use or for increasing displacement (to be reassembled with original valve springs).

In all cases, we strongly advise you to entrust the assembly of these products to people with the necessary skills and the appropriate tools. Two complete sets of shimming discs will allow proper adjustment.
