OEM Sur Ron Ultra Bee Primary Drive Rear Pulley. This component plays a crucial role in transferring power from the motor to the wheel, making it an essential part of your bike.
As time passes, the pulley naturally experiences wear and tear. When its teeth are worn or damaged, it’s a clear sign that it’s time for a replacement.
A worn pulley increases the chances of belt slippage, rupture, and premature wear. A snapped belt means having to push your bike home, not the coolest memory you’d want with your Ultra Bee!
