Primary Belt to Chain Conversion Kit | 420 RK MXU | Bonnell 805

$111.00


NOTIFY ME WHEN IN STOCK

Bonnell 805 Primary Chain Drive Kit With 420 RK MXU Sealed Chain

If you are running your rocket ship 805 in high power mode a lot, you will fail a belt soon! Replace the stock belt and pulleys with a DirtyBike Chain drive kit!

  • Strong and reliable RK chain
  • Hardened steel sprockets
  • 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. 

Aligning the mid shaft shaft and swing arm will be much easier with the DirtyBike Ultra Bee Swingarm Alignment Tool!
