Multivar
Years of experience on the race track have
spurred us to create a special automatic speed
change gear for racing. The kit contains a 101 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 guarantee
a constant coeff icient of friction, calculated to
prevent both belt slip and premature wear.
To satisfy the innumerable calibrations required
by racing scooters, depending on track type and
tuning of the motor, the kit contains 2 series of 6
rollers set and a counterspring in pre-hardened
silicon-chrome steel alloy with counterclockwise
(racing) winding.
In addition, other springs of the same class with
diff erent loads are available as options.

ATTENTION
Multivar is supplied complete of all parts; it is not
necessary to fit covers or other parts not provided
in our kit. The covers fitted on the original
variators have the function of retaining the grease.
Multivar works without grease and the working
parts are built with self-lubricating materials;
this is the reason why Multivar does not require
the cover.
ATTENTION
Always verify that the correct components are
being used, during assembly, so that the variator
nut will seat fully and make sure the hub-spacer
assembly, wherever present, has the same total
dimension as the original. The ever-changing
engine designs may cause a compatibility issue
for Malossi products. In order to avoid damage to
the vehicle we ask you to make sure the assembly
is correct. We are not responsible for any
damages to the vehicle.
