AFAM 520 Sprocket And Chain Kit - Quick Acceleration

The AFAM 520 SPROCKET AND CHAIN KIT - QUICK ACCELERATION includes:

One Front and One Rear sprocket:

• Front is a precision-machined, heat-treated, steel sprocket with one less tooth versus stock.
• Rear is a precision-machined, heat-treated, 7075-T6 aluminum sprocket with one more tooth versus stock.

And your choice of ONE of the following chains:

D.I.D. 520 ERV3:

• High-performance, lightweight, low-friction X-ring chain designed exclusively for racing.
• Pins for ER chains are put through a patented heat-treatment process that produces a surface 1.5 times harder than conventional carbon heat treating.
• Chain has gold plates and comes supplied with a rivet style master link.
• Used by most factory race teams worldwide.

D.I.D. 520 VX2:

• High-alloy steel plates and pins, solid bushings and rollers, shot-peening of plates, pins and rollers.
• Performance-enhancing pre-stretching.
• "Gold" outer, black inner plates.
• Greater rigidity which brings smoother handling, reduced power loss, and quicker response.
• Highest value in all D.I.D. series.
• Superior longer life than previous VM series.
• Tensile strength: 8,210 pounds .

D.I.D. 520 ZVMX:

• D.I.D.'s engineers are continuously improving chain designs in order to handle the tremendous horsepower loads of today's high performance motorcycles.
• In developing the new DID ZVM-X series, D.I.D. focused on "Rigidity." Traditionally, "Tensile Strength" has been the bench-mark to indicate overall strength, but Tensile Strength is only a laboratory static measurement of a chain's fracture point. Rigidity, on the other hand, is the ability of a chain to withstand the forces that occur in the real world that riders experience.
• Increased Rigidity means better power transfer from the engine to the ground, greater resistance to stretching under load and overall improved performance that meets the demands of our current high-performance bikes and the people who ride them.
• Gold and Black color.
• 120 link X-ring chain.
• Rivet connecting link included.
• Rated to 1200 cc.
