It's no secret that the performance of any vehicle depends not only on the engine but also on its transmission. Gear ratios really matter and selecting the right gear, you can use engine torque in the most efficient way. When it comes to a continuously variable transmission, or variator, it has no gears. However, it doesn't mean that you cannot adapt the transmission to your requirements concerning motor thrust at low or high RPM. The modern market offers many performance clutch kits whose parameters are altered to meet a variety of demands.

Thanks to the altered weight of rollers, modified springs, and some other solutions, you can make your motorcycle or scooter accelerate at higher or lower revs under the same conditions as before. In a nutshell, lighter rollers found inside the drive pulley will give you higher RPM, while the heavier ones will do the opposite. As for a contra spring installed in the same pulley, a lighter spring will make the variator shift at a lower RPM, and the heavier one will produce the opposite effect.

There must be a fine balance between the weight of rollers and the stiffness of the spring, and it's often achieved through trial and error. Our online store offers you a large assortment of variators & components enabling you to modify and tune up your bike. Whether you choose a complete clutch kit or individual parts, their strong construction and first-class materials will contribute to a long lifespan of the assembly. Besides performance-oriented products, we carry a wide range of replacement components. Crafted by leading aftermarket manufacturers, they are of the same high quality as original equipment, but their price is usually more budget-friendly. They will perfectly fit your motorcycle and make it run at its peak performance.
