+ whats the difference between the visco drive and a slipper clutch

[glypo]

Not much in terms of ali.

Your best bet is an alloy idler, a slipper and full ti.

A visco is a fluid drive to absorb shock, whereas a slipper is torque control system. Which basically limits the power to the wheels under acceleration (to stop wheelspin, wheelies and general loss of control).
