Vortex 435KV4-46 Aluminum Rear Sprocket 46-Tooth 520-Pitch

The Vortex 435KV4-46 is a lightweight, CNC-machined aluminum rear drive sprocket designed for 520-pitch chain applications. Built to racing standards, this 46-tooth sprocket is part of Vortex's popular 435 series and is engineered as a high-performance replacement for stock rear sprockets on compatible Kawasaki, Suzuki, and Yamaha motorcycles.

Key Features:

• 46 Teeth / 520-Pitch — designed for stock 520-size chain or suitable 520 conversion applications
• Lightweight aluminum construction — reduces rotating mass for improved acceleration and throttle response
• 100% CNC manufactured in the USA — precision machined to the tightest tolerances for a perfectly concentric sprocket every time
• Specially formulated alloy — per Vortex's proprietary specifications for optimal strength-to-weight ratio
• CAT5 color anodized finish (KV4) — electrically coated for a bright appearance; color anodizing excludes sweeps, mud grooves, and teeth for a contrasting machined-silver accent look
• Silver anodized tooth and mud groove areas — helps resist corrosion on high-wear surfaces
• Vortex patented saber tooth groove design — unique tooth geometry increases sprocket longevity and reduces chain wear
• Improved chain engagement — perfected tooth profile reduces drag and friction for better acceleration and deceleration performance
