The choice of roller weights plays an essential role when optimizing and setting the variomatic pulley in your drivetrain. In general: The lighter the roller weights, the greater the number of revolutions required to push the roller weights outward 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 rpm, heavier weights set the scooter moving at lower rpm. The turns in which the scooter comes and you can set up to your individual taste or needs. Other factors that influence the weight of the rollers set up include the general state 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. The 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, along with a special 'secret' ingredient. HT roller roller weights are excellent performers on all tuned engines and also increase the amount of rpm (and therefore speed) available from the engine's standard set up. MALOSSI HT variomatic roller weights are available in all popular sizes 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 power, or alternatively, the road or track conditions. Don't forget: The more highly tuned the motor, the more extreme the effect of adjusting the weight values ​​of the roller will be, in both directions! Try to avoid adjusting the weightings in large steps, in this particular case, less is definitely more! However: exact tuning of the weight of the rollers contained within the variomatic unit is definitely worth the effort, ensuring that the power produced by the engine does not disappear in excessive revs.
