DirtyBike 420 Gold Series Primary Belt to Chain Conversion Kit Sealed X-Ring Surron Ultra Bee
DirtyBike 420 Gold Series Primary Belt to Chain Conversion Kit Sealed X-Ring Surron Ultra Bee
Torture-tested and proven on Ultra Bee competing in the 2023 RedBull TKO, our Sur-Ron finished ahead of all other Sur-Rons!
Dirt, sand, and mud conditions can cause primary belt slippage, leading to belt failure. Avoid this potential breakdown with DirtyBike Industries Primary Chain Drive System. Including an X-ring chain, this system is essential for serious off-roaders and retains the original gear ratio.
420 Sealed X-ring chain with master link can be replaced easily without removing the swing arm.
Be sure to include the DirtyBike Ultra Bee Swingarm alignment tool! Makes the job of aligning the mid shaft shaft and swing arm much easier.
Note: As of May 2024 the alignment shim is no longer necessary so one will not be included in the kit.
