Specs At A Glance

Good To Know

Q: How do I know when my drive belt needs replacing? A: Watch for cracking, glazing, frayed edges, or a drop in acceleration and top speed. Measuring the belt width against the factory spec is the most reliable check.

Q: Should I break in a new drive belt? A: Riding gently for the first 15 to 20 minutes lets the belt seat properly onto the clutch sheaves. Avoid hard launches during that initial period to extend belt life.

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