Description
DirtyBike Industries' Primary Belt to Chain Conversion Kit replaces the stock primary belt with a premium 420 sealed chain drive system to minimize drag, reduce chain noise, and provide a longer-lasting primary drive system.
Chain included by application:
- Surron LBX: RK GB420MXU Sealed Chain
- E Ride Pro 2.0/3.0, E Ride Pro SR: 420 Sealed X-Ring Chain
If you ride in dusty, sandy, or muddy conditions, your primary belt can slip and eventually fail, possibly leaving you stranded. Don't let this happen! Install a DirtyBike Industries Primary Chain Drive System. With a much stronger chain, this is a necessary upgrade for serious off-road riders while maintaining the stock gear ratio.
Both included chains are designed for outstanding strength, quiet operation, and long service life. The RK GB420MXU is one of the strongest and quietest premium 420 sealed chains available, while the 420 Sealed X-Ring Chain features a sealed X-ring design that retains lubrication, keeps contaminants out, and delivers excellent durability with reduced maintenance.
A master link is included for easier installation, allowing the chain to be replaced without removing the swingarm.
Each kit also includes the DirtyBike Industries exclusive 1mm aluminum alignment shim, allowing you to fine-tune sprocket alignment for quieter operation and maximum drivetrain life.
