1P39QMB shortcase / Tire Size 3.50-10" Rim

Description: Naraku Brand Premium CVT Drive Belt size 669x18x30 are made in Taiwan, not China version. Its material used is Nylon previously used in making bullet-proof vests. Nylon strong yet its flexible not harsh on aluminum driveface like "Kevlar" which are recommended for heavier duty off-road applications. Nylon makes it gentle on CVT recommended for everyday riding use. Standard fit for 139QMB 50cc 4-stroke ATVs and Street Scooters with 10-inch rear wheel shortcase engine.

NOTE: How tell if you have 139QMB longcase or shortcase? If the distance from variator nut to clutch bell nut is 8.75", then it takes a 669-CVT belt which makes it a shortcase. If the distance from variator nut to clutch bell nut is 10", then it takes a 729-CVT belt which makes it a longcase. For we can’t always tell by rim size alone, for example, if the 139QMB Scooter has a 10" rim it can be tire size 3.50-10 (use 669-CVT belt shortcase) or have a tire size 130/90-10 (use 729-CVT belt longcase).
