Steel Flywheels
Made from high quality steel, precision machined, heat treated, with steel ring gear heat-shrunk and welded to flywheel, bolts included to attach flywheel to rear counterweight, price includes rear counterweight. Weight (including rear counterweight) is approximately 18 pounds. This is very close to the weight of the stock flywheel, but the weight is distributed more towards the center for significantly reduced inertia. This will allow the engine to rev up and down quicker, and will improve acceleration in the mid range. (3k-6k rpm)

Weight, including rear counterweight, is approximately 12 pounds. This is a significant savings of weight over the stock flywheel, and the weight is concentrated more towards the center. This will significantly decrease inertia, resulting in improved acceleration through the gears.
