I have a Vino 125 I bought new, with 26,000 miles on it (mostly highway, at full throttle) Yamaha recommends replacing the belt at 12,000 miles. I replaced the first and second belts at around 10,000 miles, and while they showed some wear, there was no actual damage. The third belt (oem Yamaha) failed at 4,000 miles. Completely shredded. Since I have other scooters, I let it sit for some time before fixing it. I completely disassembled the entire variator, looking for a problem, but found nothing. No wear, no damage. There was a ring of rubber stuck to both sides of the front pulley, which I cleaned off. It was right on the outside edge. I assumed it was caused by the fact that riding mostly full throttle, that is where the belt spent most of it's time. (I found the same when I replaced the belts the first 2 times) Since I replaced the broken belt I have put another 2,000 miles on it, but am afraid to get too far from home, in case the belt breaks again. I replaced the rollers at 20,000 miles, they showed no real wear. Everything is completely stock. Any ideas about what might have caused the third belt to fail so soon, when the first two lasted 10,000 miles and never broke? It still performs the same way it did when new.
