There are 2 different styles of belt in use of 50cc BTM scooters. The QT-12 uses 12” style belt and the QT-11, QT-7 and QT-9 use 10” style belts. Some exceptions to this general rule is where the scooter is a QT-7 with 12” wheels it will require a 12” short belt and a QT-9S will require a 12” belt.

There are various sizes for the 12" belt, please check the dimensions on your current belt before purchasing. Other 12" wheel belt dimensions we stock are 788 17 28 and 729 17.5 30. If you required wither of these 2 belts please ensure you confirm this in the checkout otherwise you will be sent the standard 12" belt.

A simple rule to follow is if your scooter has 10” wheels you require a 10” belt if your scooter has 12” wheel you will require a 12” belt.
