Vortex 245A-41 520-Pitch 41-Tooth Aluminum Rear Sprocket Silver

The Vortex 245A-41 is a 41-tooth, 520-pitch aluminum rear drive sprocket designed for 520 chain conversion applications on street sportbikes. Engineered and manufactured in the USA, this sprocket delivers race-proven performance in a lightweight package that outperforms heavier OEM steel setups.

Key Features:

• 520 Chain Pitch: Designed for 520-size OEM replacements or 520 conversion applications — must be paired with a matching 520-pitch front sprocket and chain
• 41-Tooth Count: Rear sprocket tooth count for precise gearing tuning
• Lightweight CAT5 Aluminum Construction: Specially formulated alloy per Vortex specifications — approximately half the weight of a comparable steel sprocket
• 100% CNC Machined in the USA: Precision manufacturing ensures concentricity and consistent chain engagement
• Silver Anodized Finish: Clear-coated silver anodize protects against oxidation and corrosion
• Saber Tooth Groove Design: Vortex patented tooth profile enhances chain engagement and extends sprocket longevity
• Vortex Patented Sprocket Design: Iconic CAT5 profile unlike any competing sprocket on the market

Converting to a 520-pitch drivetrain reduces rotational mass on both the sprocket and chain, resulting in a more responsive throttle feel and improved rear-wheel power delivery. The Vortex 245A-41 is a popular choice for sportbike riders looking to optimize gearing and shed drivetrain weight without sacrificing durability. Sold individually.
