Trail Tune is our most versatile and aggressive tune. It’s sporty and supportive, designed for going fast over a wide variety of terrain.

MX Tune is purpose-built for motocross performance. Its race-focused setup delivers the balance, control, and bottoming resistance needed to charge through big jumps, hammer whoops, and attack fast corners at race pace.

SX Tune is built for the biggest hits, hardest landings, and highest speeds. It's our stiffest, most aggressive suspension setup, engineered for pro-level riders who demand maximum support when pushing the limits. PRO-LEVEL RIDERS ONLY
