Belt size is given as width and outer length; it can change even between model years of the same engine, so match it by part number or model year. Manufacturers such as Bando, Mitsuboshi and Gates make replacement belts to original specifications.

## When to replace it

Owner's manuals typically list 15,000–25,000 km. Replace the belt earlier if the edges are worn, it is cracked, cogs are missing or the width is below the service limit. A snapped belt leaves the scooter stranded and can damage the variator cover.

When changing the belt, also check the [rollers](https://motorsikletparcasi.com/en/glossary/variator-rollers), sliders and the rear pulley faces.
