Malossi HTQ Secondary Gearbox 26/40 for Yamaha XP 500 T-Max – longer gear ratio for more top speed

If you install a tuning cylinder on your Yamaha XP 500 T-Max or generally increase the engine's power, the engine often cannot cleanly convert this power into actual top speed. The reason is usually the relatively short final gear ratio chosen from the factory: at higher speeds, the RPM increases rapidly, the engine "redlines" – and the maximum speed only increases minimally.

This is exactly where the Malossi HTQ Secondary Gearbox 26/40 comes in. The gears and intermediate shafts are processed to a first-class standard and help you bring the final RPMs back to a pleasant level – and simultaneously increase the maximum speed noticeably. For many setups of the Yamaha T-Max 500, this is the right basis to ensure that existing power is not wasted.

And don't worry about the typical hearsay stories: a longer gear ratio does not automatically mean poorer acceleration. Often, minimally stiffer clutch springs are enough to compensate for this cleanly. On the contrary: if the gearbox is too short for the horsepower available on your Yamaha XP 500 T-Max, power is lost even though the engine could clearly "pull" more.
