22T Front Sprocket and 51T Rear Sprocket is the stock gearing.

KIT INCLUDES:
Transmission Sprocket

  • Heat Treated Steel
  • 22, 23 or 24 Tooth

Steel Rear Wheel Sprocket

  • Full thickness for 530 Chain, beware of other thin .25 thickness sprockets out there.
  • Steel Sprockets last longer than aluminum sprockets and are ideal for high load situations (Burnouts, Wheelies, High Horsepower Engines)
  • Black Powdercoat Steel or Chrome plated Steel
  • 48, 49, or 51 Tooth Available

Transmission Nut Lock Plate

Transmission Super Nut

Grade 8 Hardware for rear sprocket


Chain Info:

530 O-Ring(BMOR) Chain

  • 9,700lbs Tensile Strength
  • Includes Rivet Master Link
  • Component designs optimized with computer analysis provides higher tensile strength.
  • Specially controlled heat treatment means tougher material.
  • Reinforced roller offers higher impact resistance and longer durability.
  • Available in Natural, Black, Gold or Black/Gold

530 X-Ring (BMXR) Chain

  • 9,700lbs Tensile Strength
  • Offering 1.5 to 2x longer wear resistance than regular O-ring chains.
  • Each refined component, designed with computer analysis, provides higher tensile strength.
  • Specially controlled heat treatment means tougher material and more durability.
  • Quad seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strength.
  • Quad seal ring offers less friction, which minimizes power loss, almost half that of standard O-ring chain.
     

530 High Strength BMZR Chain- Recommended for all baggers

  • 11,200lbs Tensile Strength
  • Includes Rivet Master Link
  • Specifically developed for today's high-performance sport machines.
  • High-quality components coupled with a factory-greased seal ring ensures superior rigidity.
  • High-tensile steels used throughout the chain components; larger pins mean loads spread out over wider area, resulting in longer life and more strength.
  • Specially controlled heat treatment means tougher material and more durability.
  • Available in Chrome, Black, Gold or Black/Gold

530 EK 3D Chain- High Strength, Recommended for all baggers

3D parts are precisely manufactured, leading to a greater improvement of transmission efficiency, better acceleration and efficient engine work.
Features an original special plate with a lightening hole. EK creates a hole on both ends of a pin to lighten the chain without weakening the plate according to computer analysis. The edge-cut inner plate reduces friction and realizes smooth engagement with sprocket. This plate enables the chain to be light, removes mud from the hole and dissipates heat effectively.

  • 11,400lbs Tensile Strength
  • Includes Rivet Master Link
  • Reduced friction
  • Chromium carbide pin with lighten hole in end
  • Inner plate with lighten hole
  • Dimpled outer plate.
  • QX-2 ring
