I have a peugeot Elystar scooter. Still with the original engine I did more than 6000 km on it. It performed very well , I replaced it with a new one due to loss of width. Unfortunately, after tuning the engine it quickly broke after 200 km. I switched to a Polini 765 aramid belt this one lasts everything.
The belt is good. You can ride it a little without any problems. The material from which it is made you can see that it is quite strong. The only downside is that the belt is quite inflexible, so you may have problems at first to put it on. But I still highly recommend this drive belt.
The belt perfectly fits 139QMB 4T engines as described reinforced. After driving 1000km and inspecting the drive everything turns out to be in place and most importantly the belt does not fall apart or shear, may it last as long as possible!
Belt of very good quality, fits perfectly. The operation of the scooter on the new belt is no different from the original one. The length is also the same. Made 4tys km and nothing happens to it. I recommend
The belt is great, after driving 500km I took off the cover. To my surprise the belt didn't even wear out. There was no black dust everywhere, which is found even in more expensive belts.
