Good To Know

Q: How do I know when my drive belt needs replacing? A: Cracks, glazing, frayed edges, or a drop in top speed are common signs a belt is worn out. Replacing it before it fails helps avoid being stranded on the trail.

Q: Should I break in a new drive belt? A: A short easy ride at moderate speeds lets the belt seat against the clutch sheaves. This helps it wear evenly and last longer.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
