Vortex CK2150 Chain and Sprocket Kit Gearing - 520RV3 15/41

The Vortex CK2150 is a complete, ready-to-install 520 chain and sprocket kit featuring the high-performance RV3 Series chain and a laser-cut steel rear sprocket. Designed as a direct drop-in replacement with a one-tooth-down front sprocket configuration, this kit delivers improved low-end torque and quicker acceleration compared to stock gearing.

Chain Performance:

• 520RV3 Series chain — 114 links, pre-cut to the correct length with no chain cutting required
• Features a dual pocket sealing system for up to 7 times longer wear life than standard O-ring chains
• Manufactured in Japan to the highest quality specifications in the industry
• Includes a rivet-type master link; clip-type master links available separately

Sprocket Specifications:

• Front sprocket: 15 teeth (OE: 16 teeth)
• Rear sprocket: 41 teeth (matches OE)
• Laser-cut steel rear sprocket for durability and precise fitment
• OE reference gearing: 16/41 | Kit gearing: 15/41

Kit Includes:

• 1x 520RV3 chain — 114 links
• 1x Front (countershaft) sprocket — 15T
• 1x Rear sprocket — 41T
• 1x Rivet-type master link

This kit ships as a complete, pre-matched set — no additional components needed for installation. The gearing change (one tooth down in front) sharpens throttle response and improves acceleration out of corners, making this an excellent upgrade for street and track riding.
