Vortex 196AV4-43 V4 Aluminum Rear Sprocket 520 Pitch 43T Silver

The Vortex 196AV4-43 is a 43-tooth, 520-pitch aluminum rear sprocket built on Vortex's next-generation V4 design — an evolution of the iconic CAT5 platform engineered to deliver a 10–15% reduction in weight without sacrificing strength. Like all Vortex aluminum sprockets, it is 100% CNC machined in the USA from a specially formulated aerospace-grade aluminum alloy to precise tolerances, giving riders a significant rotational weight savings over steel counterparts.

Key Features:

• V4 design: New lightening pattern with machined faces on both sides for maximum weight reduction while maintaining structural integrity
• 520 chain pitch — compatible with 520 OEM or 520 conversion chain setups
• 43-tooth rear sprocket for precise gear ratio tuning
• 100% CNC machined from aerospace-grade aluminum alloy per Vortex specifications
• Silver finish with clear protective coating to resist oxidation
• Vortex patented tooth design with saber tooth grooves for increased sprocket longevity
• Manufactured in the USA

Aluminum sprockets are the preferred choice for road racing, motocross, flat track, and drag racing applications where rotational weight savings translate directly into improved acceleration, deceleration, and directional response. For optimal service life, clean and re-tension the chain every 300–600 miles on street bikes, or after every ride on dirt bikes.
