Product Description
DirtyBike's 420 Sealed X Ring Standard Primary Chain Drive System For Sur-Ron Ultra Bee.
Torture-tested in the 2024 RedBull TKO Extreme Enduro where it performed flawlessly.
- More Efficient Than Belt
- Better Acceleration
- Longer Run Time
- Easy Maintenance
- Similar To Stock Gear Ratio
- Chain can be replaced without removing the swing arm
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. Make the job of aligning the mid shaft shaft and swing arm much easier with a DirtyBike Ultra Bee Swingarm Alignment Tool.
There is a good reason that we do not offer a 520 size chain for this bike. Over the same size sprocket a larger chain will create more heat because the larger links have to articulate considerably more that a smaller chain. This extra movement creates excess heat which can cause chain failure sooner.
Note: If you are planning to use this kit with the EMBX XUB-80 motor the front sprocket will require modification. Please contact us for more information.
