One of the best kept secrets to lessen wheelies and optimize acceleration among top drag racers for years, this heavy spacer replaces the light aluminum spacer in between the front wheel bearings. It doesn’t spin and is located at the furthermost point from the rear axle, for maximum downward pressure on the front wheel and maximum weight transfer to the rear wheel. Works great to prevent wheelies from stock wheelbase to grudge applications and everything in between… and it’s undetectable if your bike likes to wheelie on the street! Decreases in ET vary per application, but one to two tenths improvement is common. Adding this heavy spacer is the equivalent of adding as much as 25 lbs. to the lower fairing nose in a 68” wheelbase application!
