Ultra Bee Primary Chain Drive Enduro Kit With 420 RK MXU Sealed Chain
For serious off road and enduro racers the sealed RK chain kit is super durable and will last longer between lubes than non-sealed chain kits.
- 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
Aligning the mid shaft shaft and swing arm will be much easier with the 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.
