By reducing the weight of the flywheel over the standard X-flow item to as little as a half, the resulting reduced inertia gives better acceleration, especially in the lower gears. In addition, the reduced weight at the flywheel edges allows quicker gear changes, and increased engine braking. Comes with integral starter ring (ring gear is machined into the flywheel).
