Description
219 Primary Belt to Chain Conversion Kit
Upgrade your stock primary belt drive with the DirtyBike Industries 219 Primary Chain Drive System. Designed for riders looking for a lighter, quieter, and more durable drivetrain, this conversion maintains the factory gear ratio while delivering improved reliability and reduced maintenance compared to the stock belt.
Chain Options
Choose the chain that best fits your riding style and application.
Sealed O-Ring Chain
The Sealed O-Ring option is the best choice for most riders, offering quieter operation, longer service life, and reduced maintenance. The sealed O-rings retain lubrication while keeping dirt and debris out, making it ideal for on-road and off-road riding.
Depending on the selected bike, the kit includes either an RK 219 Sealed O-Ring Chain or an RLV 219 KRO Sealed O-Ring Chain. Both provide excellent durability and smooth, quiet operation, while the RLV KRO is regarded as the quietest 219 chain offered by DirtyBike Industries.
Non-Sealed Gold Series Chain
The Non-Sealed Gold Series option is designed for riders who prioritize maximum performance and efficiency. Its lightweight, low-drag design reduces rotating mass and drivetrain losses but requires more frequent cleaning and lubrication than a sealed chain.
Depending on the selected bike, the kit includes the RK 219 Non-Sealed Gold Series Chain.
If you ride in dusty, sandy, or muddy conditions, the stock primary belt can slip and eventually fail, potentially leaving you stranded. Replace it with a DirtyBike Industries Primary Chain Drive System for a stronger, more dependable drivetrain that is approximately 20% lighter than the stock belt system while maintaining the factory gear ratio.
Each kit features one-piece, heat-treated steel sprockets engineered for reduced wear and longer service life. The updated sprocket design also provides additional chain adjustment to help maximize drivetrain life.
