Motor Woodruff Key
The OEM Woodruff key for the Surron Ultra Bee motor. It locks the motor drive sprocket to the motor shaft, and it is what actually carries drive torque between the two rather than the clamping force of the sprocket fastener.
Sold as a single item, shipping weight 0.13 lb. Verified against the Surron Ultra Bee. Fit a new key any time the drive sprocket comes off. A key that has begun to round lets the sprocket move a fraction under load, and that movement works the keyway in the shaft itself, which is the part you cannot replace on its own.
