Vortex 435ZR-45 Red 45-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 435ZR-45 is a 45-tooth, 520-pitch rear sprocket machined from lightweight CAT5 aluminum and finished in a vibrant anodized red with contrasting silver machine cuts. Designed for sport and performance motorcycle applications, this sprocket is a direct OEM replacement for 520-pitch setups and is also suitable for 520 conversion builds.

Key Features:

• Lightweight CAT5 aluminum construction — reduces unsprung rotational mass for improved throttle response and acceleration
• 100% CNC manufactured in the USA — tight tolerances ensure precise fitment and consistent performance
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Patented saber tooth groove design — unique tooth geometry increases sprocket longevity and reduces chain wear
• Anodized red finish with contrasting silver machined accents — available in four colors in most sizes
• 45 teeth, 520 pitch — compatible with standard 520-pitch OEM chains and aftermarket 520 conversion kits

Vortex sprockets are a popular upgrade among track-day enthusiasts and racers looking to shed weight without sacrificing durability. The patented tooth profile distributes load more evenly across the chain, extending the service life of both the sprocket and chain.
