The
Vortex clutches are different from other clutches in many respects. One
important difference is the clutch is built in two parts - the clutch assembly
and the sprocket assembly.
The
Vortex RED and Vortex BLACK use essentially the same clutch assembly. It
consists of springs, levers, rollers, drive hub, discs and drive plates.
The
difference between RED and BLACK is in the sprocket assembly. The Vortex
BLACK is built with an old fashion sprocket (flats and retaining ring) and
spins on a needle bearing. The Vortex RED is built with a high precision
ball bearing and a screw-in sprocket.
The
advantages of the Vortex RED are:
- An extremely large
(200-300%) improvement in disc and drum life (abrasive wear between disc
tangs and drum slots)
- Stronger connection between
the steel sprocket and aluminum drum (especially important for the more
powerful engines)
- Ball bearings in all
sizes including the 11 tooth sprockets (no bronze bushings)
- Sealed bearings that exclude
dirt and retain grease (less maintenance)
- Fewer parts. There are no
thrust washers, machine screws or external retaining rings.
- A small improvement in
acceleration especially with 15T sprockets and larger where the bearing
can be centered exactly in line with the chain.
It is possible to retrofit a Vortex RED sprocket assembly to a Vortex BLACK clutch assembly with a simple change in mounting hardware.
