The kit is aimed at motocross riders seeking a lightweight and responsive transmission: reduced unsprung mass, choice of ratios suited to the terrain, and a gold finish for a racing look. Compatible with many 250cc off-road bikes — notably HUSQVARNA WR 250 (1999 and 2000) — it is suitable for a restoration or a transition to competition setup. Be sure to check the exact compatibility with your model and regularly monitor tension and lubrication to optimize the longevity of the transmission.
