•1dHi, I recently serviced my Aerox 155, and the workshop replaced the V-belt. In the bill description, it says "V-belt kit" with the code BLVWB0310000. Is this genuinely meant for the Aerox, or is it a part used for lower-capacity scooters?

The code BLVWB0310000 reads like a Yamaha India workshop “V-belt kit” billing code. The actual belt itself usually carries a different Yamaha part number on the pouch and is even printed on the belt, commonly starting with BLV or B65 for the 155cc scooters. Belts on other scooters like the Fascino and RayZR are narrower and shorter. They either won’t fit or you’d immediately get slip, high revs and poor speed.
If after your service, acceleration is smooth, cruising rpm feels normal, and top speed is unchanged, the belt is right. If you feel flary revs, sluggish pull, or a drop in max speed, raise it with the workshop. If you want to be 100% sure, ask them for the belt wrapper or a photo of the printing on the belt.
