The stock Harley davidson xr1200 and XR1200X belt tensioner ( black version ) is designed to keep the belt under constant tension, except it doesn’t. When the suspension is completely unloaded, such as when pulling stoppies or even braking hard, the tension is increased to an alarming degree, which can actually damage belts, wheel bearings and pulley bearings. This spring loaded item is designed to maintain a tension of 10.5kg (depending on model) regardless of swingarm position and will help lengthen belt and bearing life. Utilises stock tensioner wheel.
Attention: the pulley is not included.
