DirtyBike RK Gold Series 219 Primary Chain Drive Kit | Surron Light Bee, Segway X160/X260

Lighter, Stronger, And Built To Outlast Your Stock Belt System

The stock primary belt system works well until you start pushing your bike harder. Aggressive riding, power upgrades, larger tires, and high torque setups can put additional stress on the factory belt system. When that happens, many riders move to a primary chain conversion for increased durability and long-term reliability.

DirtyBike Industries developed this RK Gold Series 219 Primary Chain Drive Kit for riders who want the proven strength of a chain setup while keeping noise levels lower and preserving the factory gear ratio. Unlike larger chain systems, the 219 setup stays significantly quieter than traditional 420 conversions while still delivering excellent strength and reduced rotating weight.

The highlight of this system is the premium RK GB219KR endless racing chain. RK has earned more than 50 World Kart Championships, making this one of the most proven 219 chains available. Combined with upgraded steel sprockets and reduced overall system weight, this kit delivers a stronger and more responsive drivetrain package.
