Specific cut-outs prevent the accumulation of mud, sand or grit, which extends transmission life and reduces premature wear.

Perfect fit thanks to meticulous machining for easy assembly.

Forged and precision-machined for superior durability and wear resistance.

Provides superior hardness, up to six times longer service life than a 7075-T6 aluminum crown.

Much lighter than a steel crown, which reduces unsprung mass and improves the bike's responsiveness.

Increases mechanical strength and reduces surface tension, improving durability

Allows original replacement or modification of gear ratios to adapt engine behavior (acceleration vs. top speed).

Fully heat-treated to withstand the rigors of enduro, motocross and off-road riding.

Suitable for both original replacement and modification of the gearing to suit your needs.

Smoother, quieter transmission, reducing vibrations and improving responsiveness.

Made from carbon steel or heat-treated alloy, guaranteeing exceptional strength and long service life.

Specially developed for extreme racing conditions.
