FAQs
Does this belt fit all Yamaha T-MAX years?
This specific MPN 248.086 is designed for specific Yamaha T-MAX generations; always cross-reference your specific scooter year and model against the Polini fitment chart.
Do I need to adjust my variator weights when using this belt?
While it is not strictly required, many riders find that fine-tuning variator weights can complement the performance characteristics of an aramid belt.
How long is the typical break-in period?
We recommend at least 50-100 kilometers of mixed, moderate riding to ensure the belt surfaces bed in correctly.
Can I use this for racing?
Yes, the aramid construction is specifically designed to handle the high heat and stress associated with performance and racing applications.
What happens if I install the belt incorrectly?
Installing the belt in the wrong direction or with improper tension can lead to decreased performance, excessive noise, and premature belt failure.
Troubleshooting
Belt slipping during acceleration
Check that the variator faces were cleaned of all oil/grease before installation and verify proper belt tension.
Excessive noise or vibration
Ensure the belt is not installed backwards (check for directional arrows) and verify that all variator components are tightened to factory specifications.
Premature wear
Inspect the variator rollers and sliding pieces for flat spots or damage, as worn components can cause uneven belt wear.
Pros and Cons

Setup, Compatibility & Care
Compatibility is limited to Yamaha T-MAX models. Installation should be performed by someone familiar with scooter CVT transmission systems, as proper belt tension and variator alignment are crucial for success.
- Preparation: Clean the variator faces thoroughly with a degreaser to remove any residue from the old belt.
- Installation: Ensure the belt is seated properly at the lowest point of the pulleys before tensioning.
- Break-in: Avoid full-throttle acceleration for the first 50-100 kilometers to allow the belt to 'seat' into the variator faces.
- Care: Periodically inspect the belt for signs of fraying or uneven wear during standard service intervals. Avoid using chemical sprays directly on the belt surface.
