These are offset bushings for use on many Yamaha cruiser triple trees (see fitment data). These hardmount bushings have an offset hole which allows adjusting the spread of the risers or hardmount bars. By doing this it is possible to mount a set of Harley-Davidson bars or any risers that have a Harley-Davidson spaced top-plate. You are no longer limited to the parts in only the metric market! Buy the bars or risers you really want and use our bushings to be able to mount them up.
A standard spread for Yamaha triple trees is 100 mm (3.937″), whereas Harley-Davidson and other Imperial-based models typically have a 3 1/2″ (88.9 mm) spread.
