Automatic Belt Tensioner For Buell XB

Black anodized finish.
Too high tension, found on the original belt tensioner, is a common cause of belt failure.
This upgraded direct replacement belt tensioner dramatically reduces tension and will improve belt life expectancy.
Wheels and even more transmission bearings will also benefit from less unnecessary load.

Fits: > 02-07 XB9R/S, XB12R/S.
