These new precision machined billet axle blocks utilize a YZ250 axle allowing the left axle block to float similar to the Japanese design. The Japanese axle which is forged also provides a little more flex that the stock axle which is just a pipe with threads on each end. Advantages are better tire traction and more comfort from the rear of the motorcycle under hard acceleration. Weighs just under the stock system.
Includes YZ250 axle (1C3-25381-90-00), nut (90185-20002-00) and washer (90201-20020-00).
