The main role in tuning a variomatic scooter is the weight. Rule of thumb: The lighter your roller set, the more revolutions are needed to push outward rolls through the centrifugal motion to set gear shifting on the go. Heavier rollers need to lower the rpm to start this process. This means that if your scooter is lighter it rolls it will need higher revs to start moving. Heavier rollers allow you to start moving at low rpm. Each driver will have to find out which level of laps is right for them. A lot of factors in this decision: the degree of tuning, the weight of the drivers, what weight (of rolls) are optimal, etc. Knowing the overabundance of inadequate material on the market, we can only recommend various rolls from renowned POLINI studios and MALOSSI. Their products are manufacture.
