Lightening holes and targeted reinforcements reduce weight without negatively impacting performance, making it suitable for both track use and intensive road use. State-of-the-art broaching machines ensure a precise fit on the shaft, limiting vibrations and premature wear of the transmission.

Ideal for owners of modern high-performance sports bikes (e.g. KAWASAKI Z H2 1000 ABS SE / Performance 2025), this sprocket allows you to adjust the gearing according to your torque or top speed needs while maintaining the reliability expected from a high-level OEM part.
