Vortex 527ZR-49 CAT5 530 Pitch Red 49-Tooth Rear Aluminum Sprocket

The Vortex 527ZR-49 is a CAT5 series lightweight aluminum rear sprocket featuring a 530 chain pitch and 49 teeth, finished in a bold red anodized color. Manufactured in the U.S.A., this sprocket is a high-performance upgrade over heavy OEM steel sprockets, delivering meaningful weight savings exactly where it counts — on rotating drivetrain mass.

Vortex CAT5 sprockets are machined from 7075-T6 billet aluminum, one of the highest-grade aluminum alloys available, offering an ideal balance of strength and minimal weight. The color anodizing is applied selectively, excluding the tooth sweeps, mud grooves, and teeth, resulting in a striking red finish with bright silver machine-cut highlights.

Key Features:

• CAT5 lightweight aluminum construction — significant weight reduction over stock steel sprockets
• 7075-T6 billet aluminum — aerospace-grade alloy for maximum durability and light weight
• 530 chain pitch — compatible with 530-series drive chains
• 49-tooth rear sprocket — optimized for acceleration and low-end torque tuning
• 100% CNC machined in the U.S.A. — manufactured to the tightest tolerances for perfect concentricity
• Saber tooth groove design — reduces drag and friction for improved acceleration and deceleration response
• Mud grooves — help keep chain and sprocket interface clean
• Red color anodized finish — corrosion-resistant with contrasting silver highlights
• Vortex patented sprocket design — unlike any other sprocket on the market
• Reduced rotating mass multiplies drivetrain efficiency and frees horsepower

The Vortex 527ZR-49 is an ideal choice for riders looking to fine-tune their gearing for more aggressive acceleration. Reducing rotating unsprung weight through a premium aluminum rear sprocket improves throttle response and overall drivetrain feel compared to a stock steel unit.
