Modified 1955-69 flywheels.

Currently in stock are the early heavier version flywheel CNC machined and balanced.

These are used flywheels processed as follows:

Degreased and inspected (threads, ID taper, seal surface, etc...)

CNC machined on a Fanuc ROBODRILL

Balanced to less than one gram on a Hines #500 balancer

The weight is reduced from ~5850 grams to ~2900 grams. In pounds, that is a reduction in weight of approximately 6.50 lbs.

These reduced flywheels offer the sport rider more efficient quick gearbox shifting.

These are an ideal addition to any engine build for the R69, R50S, R69S & R69US models.
