The choice of roller weights plays an essential role when optimizing and setting the variomatic pulley in your transmission. In general: The lighter the roller weights, the higher the number of revolutions required to push the roller weights out of the centrifuge and change the gear ratio. Heavier roller weights require fewer revolutions to allow the physics to take effect. This means that with lighter weights the scooter starts moving at higher RPMs, heavier weights set the scooter in motion at lower RPMs. The rides in which the scooter comes and you can set it up to your individual tastes or needs. Other factors influencing the set up roller weights include the general condition of the track, the choice of peripheral components, the weight of the rider, road and track conditions, etc. We can especially recommend the Variomatic replacement roller weights produced by the experts at MALOSSI. Malossi HT Variomatic extra roller weights possess extremely hard anti-wear, heat resistant and self-lubricating qualities. MALOSSI achieve this by using 'CBT' plastic technology in their construction, together with a special 'secret' ingredient. HT roller weights are excellent players in all tuned engines and also increase the amount of rpm (and therefore speed) available from standard engine set ups. MALOSSI HT variomatic roller weights are available in all popular formats and very fine degrees of weight difference. SIP-TIP: Weight adjustment of the variomatics roller weights allows each scooter to be set up specifically to suit the engine output, or alternatively, the road or track conditions. Don't forget: The more highly tuned the engine, the more extreme the effect of adjusting roll weight values will be, in both directions! Try to avoid adjusting the weightings in big steps, in this particular case, less is definitely more! However: the exact tuning of the weight of the rollers contained within the variomatic unit is definitely worth it, ensuring that the power produced by the motor does not disappear in excessive revs.
