The following is an exert from one of our tech articles:
The primary sheave is what we are talking about and it is the pulley in the
CVT transmission that is attached to the engine. The secondary sheave is the
one attached to the transmission.
A machined sheave is where we take the primary sheave and machine out the ends
of the slots where the roller weights ride so they can ride out further in the
sheave which pushes the belt in more which makes the belt ride higher in the
sheave thus increasing the "gear ratio" of the transmission which
in turn makes the vehicle go faster with lower RPM, kind of like overdrive if
you will.
- Presently only for modified engines
- Increase top speed to about 60mph with modified engine
- Great low end power and great top end
- Smooth roller wieght transition to avoid RPM spikes
