Product Description
Ultra Bee Primary Chain Drive Racing Kit With 420 RK MXZ Sealed Chain
For serious off road and moto racers the non-sealed RK MXZ chain kit is the most efficient kit with the least amount of parasitic drag
- 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
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.
Make the job of aligning the mid shaft shaft and swing arm much easier with a DirtyBike Ultra Bee Swingarm Alignment Tool.
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.
