This variator is designed for race scooters, and scooters with very highly tuned 70cc cylinder kits revving beyond 10,000rpm. This variator will be very difficult to tune on a scooter with ‘street’ level parts such as standard sport 70cc cylinders.
Compared to the regular the Malossi Racing Variator features a larger drive face for higher top speed, as well as a host of other small changes for increased tuning ability and power delivery.
The MHR Team Variator comes in a kit with 2 sets of rollers 3.5 gram and 3.8 gram. This kit is specifically designed to match the characteristics of the MHR Team cylinder, for scooters with more street appropriate cylinders it is recommended to use heavier rollers than the ones supplied in the kit for optimum performance.
TECHNICAL NOTES :
The kit contains a 99.5 mm diameter mobile half pulley made of a special cast aluminium alloy. The contact surface between pulley and belt is super-finished with a diamond tool to grant a constant coefficient of friction, calculated to prevent both belt slip and premature wear. To satisfy the innumerable adjustings required by racing scooters, depending on the track type and on the tuning of the engines, the kit is supplied with 2 sets of 6 rollers and a counter-spring in pre-hardened silicon-chrome steel alloy with counterclockwise winding (racing). In addition, other springs of the same class with different loads are available as options.
Suggestions for the setting
The variator is supplied with two different roller sets: one of 3.9 gr. and one of 4.7 gr. in order to change the number of revolutions of the gear curve of your vehicle perfectly adjusting its speed and acceleration.
