6 pcs Product description
The main role in tuning a scooter variomatic is weight. Rule of thumb: the lighter your roll sets, the more rpm’s are needed to push the rolls outwards through centrifugal motion to set gear change in motion. Heavier rolls need lower rpm’s to start this process.
That means if your scooter has lighter rolls it will need higher rpm’s to start moving. Heavier rolls allow you to start moving at lower rpm’s.

Each pilot will have to find out which level of rpm’s is right for them. A range of factors deal in this decision: degree of tuning, driver’s weight, which weight (of rolls) are optimal, etc.
RMS Variator weights:
: exact adjusting due to small weight steps, good quality, very best prices. Available for all common engine types and sport variators.
Here the most common sizes:
Engine type: MINARELLI 15×12, MORINI 17×12/KYMCO/PEUGEOT/HONDA/PIAGGIO/GILERA – `98 16×13, PIAGGIO/GILERA `98- 19×15,5
Sport variators: POLINI/16×13, HEBO 17×12/TOP PERFORMANCE 15×12

By changing variator rolls, every scooter can be tuned exactly to it’s motor performance or driving conditions. What you should notice: the more aggressive your motor is tuned, the more sensitive it reacts to weight variations in the rolls. Be careful not to work with weights that are too varied! Remember: exact vario tuning is really necessary so your motor doesn’t waste it’s performance in unnecessary rpm’s (too light weights) or through too early gear changes (too heavy weights) which won’t get you any acceleration.
