Vortex CK4112 V3 2.0 520MX3 Chain and Sprocket Kit 13/49

The Vortex CK4112 is a complete V3 2.0 chain and sprocket kit built for motorcycle riders who demand high-performance drive components. This kit pairs a 13-tooth front sprocket with a 49-tooth rear sprocket and a 520MX3 chain cut to 114 links — everything needed for a full drive system replacement in a single package.

Vortex Racing is a U.S.-based manufacturer with a long-standing reputation for precision-engineered motorcycle racing components used across Motocross, Supercross, Road Racing, Flat Track Racing, and Minibike competition. Each component in this kit is manufactured to tight tolerances using premium materials and validated through direct feedback from professional race teams worldwide.

Kit Includes:

• 1x Chromoly-steel front countershaft sprocket — 13 teeth (Part: 422S)
• 1x Rear sprocket — 49 teeth
• 1x Vortex 520MX3 chain — 114 links
• Rivet-type master link

Key Features:

• 520MX3 chain features a tri-glide X-ring seal design with 3 pockets of lubrication, reducing heat and friction while extending wear life significantly over standard O-ring chains
• Front sprocket is high carbon steel, nickel plated with drilled lightening holes to reduce rotating mass
• Laser-cut steel rear sprocket with electroplated satin black finish for corrosion resistance
• Case-hardened teeth for increased durability and extended service life
• Bike-specific fitment — no cutting or chain modification required for installation

Installation Note: X-ring chains are wider than standard roller chains. When installing on a motorcycle originally equipped with a non-O-ring chain, verify adequate clearance at the engine cases near the countershaft sprocket and any other points of close contact before riding.

The Vortex CK4112 delivers race-proven durability and performance, making it an excellent upgrade or direct replacement for worn OEM drive components.
