We no longer carry this, it has been replaced with this Chain Drive Kit.
DirtyBike Industries primary drive system uses a sealed X-ring chain instead of O-rings to minimize drag and reduce chain noise giving you a longer lasting drive system.
If you ride in dusty, sandy or muddy conditions you may have primary belt slippage which will eventually fail the stock primary belt, possibly leaving you stranded in the middle of nowhere. Don’t let this happen! Install a DirtyBike Industries primary chain drive system. With a much stronger chain, this is a necessary upgrade for the serious off-road rider and maintains stock gear ratio.
420 Sealed X-ring chain with master link can be replaced easily without removing the swing arm.
This kit comes with db DirtyBike Industries exclusive 1mm aluminum alignment shim allowing you to adjust the sprocket alignment for a quieter, longer lasting drive system.
