JXR 520 Chain Conversion Kit for Sur-Ron Ultra Bee

The JXR 520 chain conversion kit is a complete drivetrain upgrade for the Sur-Ron Ultra Bee, designed for riders who want maximum strength, reliability, and long-term durability.

This full kit includes both sprockets and a genuine DID ERVT X-RING chain cut to size, giving you everything needed to convert your Ultra Bee to a heavy-duty 520 chain setup. Compared to lighter chain options, a 520 conversion is ideal for aggressive off-road riding, higher torque use, and riders who want a tougher chain and sprocket combination that lasts.
