The Gates PowerGrip GT4 640-8MR-25MM Primary Belt is a direct OEM replacement and performance upgrade for the Sur Ron Ultra Bee. Designed specifically for the flanged primary pulley system, this 25mm-wide GT4 belt delivers increased torque capacity, stable tracking, and long service life for stock and high-power builds. Developed through GritShift R&D with Gates engineers. Manufactured in the USA.
Fitment:
- Sur Ron Ultra Bee
The PowerGrip GT4 construction uses a high-torque synchronous design with an optimized tooth profile that maintains correct clearance on flanged pulleys. Load is distributed evenly across the 25mm belt width, reducing heat buildup, minimizing friction, and preventing premature failure common with inferior aftermarket belts. Durable ethylene elastomer compound resists stretch and wear. Whether replacing a failed belt or upgrading ahead of time, this GT4 belt is the proven solution for Ultra Bee reliability.
