729-18-30 CVT Drive Belt for 50cc Scooters

The 729-18-30 CVT Drive Belt is made for 50cc scooters and is meant to hold up well in regular use. This OEM-grade belt is built to suit QMB139 4-stroke scooters that run 12-inch rear wheels. It belongs to a range of CVT drive belts for scooters and transfers power evenly for a smooth ride, so it works well as a reliable option for routine maintenance or replacement.

Build and Operation

This drive belt is produced in Japan to OEM standards, so it lines up properly with the scooters it is designed for. Its length is 729mm, its top width is 18mm, and its groove angle is 30 degrees. Together these measurements help the belt run efficiently and last.

Fitting Notes

Swapping out the drive belt is simple for anyone comfortable working on scooters. Because the dimensions match the original specification, it goes straight into position where the old belt came out.
