Vortex CKG6986 520 Chain and Sprocket Kit 15/47 Tooth Steel SX3 Gold Chain

The Vortex CKG6986 is a 520 chain and sprocket kit for motorcycles. It pairs a 15-tooth front sprocket with a 47-tooth rear sprocket and a Vortex SX3 chain. The result is a drivetrain replacement built around a 3.13 gearing ratio.

Key Features:

• 520 chain size with 15-tooth front and 47-tooth rear sprockets
• Steel front sprocket with drilled lightening holes to reduce rotating mass
• Front sprocket made from high carbon steel, induction hardened to reduce surface wear and nickel plated to resist corrosion
• Steel rear sprocket with a black satin electro-plated finish to resist corrosion
• Rear sprocket is cupped down from the tooth ring to the body to save weight
• Vortex SX3 X-ring chain with drilled links and improved tensile strength
• Gold chain, 112 links
• Includes a rivet-type connecting link
• HFRS series

The drilled sprockets and chain reduce rotating mass. The X-ring seals reduce friction, and the sprocket tooth design is intended to hold and release the chain cleanly.
