Primary drive system for E Ride Pro SS 2.0 3.0 now available with the best sealed 420 chain available – RK 420 GB MXU

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 primary chain drive system. With the world famous RK GB4MXU chain, this is a necessary upgrade for the serious off-road rider and maintains stock gear ratio.

RK GB420MXU Sealed chain is one of the strongest and quietest 420 chains available.

Master link makes for easier installation and the chain can be replaced easily without removing the swing arm.

Note: Some of the E Ride Pro motors have shallow woodruff keyways. It may be necessary to remove 5.mm from one side of the woodruff key to allow it to fit properly.
