Vortex 201ZR-49 CAT5 420 Rear Sprocket 49-Tooth Red Aluminum

The Vortex 201ZR-49 is a 49-tooth, 420-pitch CAT5 aluminum rear sprocket finished in a vibrant red anodize. Part of Vortex's iconic CAT5 line — introduced in 1995 and widely regarded as the industry's most recognized sprocket design — this sprocket delivers a winning combination of lightweight performance and proven durability.

Key Features:

• Lightweight aluminum construction — reduces rotating mass compared to OEM steel sprockets for improved acceleration and handling response
• 420 pitch — matches OEM chain pitch on compatible small-displacement and mini-moto applications
• 49-tooth rear sprocket — higher tooth count lowers the final drive ratio for increased low-end torque and quicker acceleration
• CAT5 patented tooth design — saber tooth grooves and Vortex's unique profile increase sprocket longevity
• Red anodized finish — color anodizing applied to the sprocket body with contrasting silver machine-cut highlights on the teeth and sweeps
• 100% CNC machined in the U.S.A. — manufactured to tight tolerances from a specially formulated alloy per Vortex specifications

The Vortex CAT5 rear sprocket is a direct-fit, bolt-on upgrade that requires no modifications to install. It is an ideal choice for riders looking to fine-tune their bike's gearing for more aggressive acceleration on the street or track.
