We torture-tested this on the Ultra Bee during the 2023 RedBull TKO, our Sur-Ron finished ahead of all other Sur-Rons. We are now ready to release it!
Dirt, sand, and mud conditions can cause primary belt slippage, leading to belt failure. Avoid this potential breakdown with the 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.
