669-18-30 CVT Drive Belt for GY6 50cc Short Case Engines
This 669-18-30 CVT drive belt is built to give your automatic scooter quick, consistent gear changes. It suits 49cc/50cc 4-stroke QMB139 short-case engines that use a 10-inch rear wheel, and it is made in Japan to OEM-level standards. If your worn or damaged belt needs replacing, this is one of the GY6 50cc scooter parts that can restore your scooter's performance.
Construction and Durability
The belt uses high-modulus synthetic rubber with high-tensile cord reinforcement. This combination resists stretching from heat and keeps its shape at high RPM. Because of this build, the belt holds up well over long periods of riding and should last longer than a standard belt.
Fitment Information
With a total outer length of 669mm, this belt is made for specific short-case setups. Check your current belt size before buying. This model will not work on long-case engines that run 12-inch or 13-inch rear wheels.
