Vortex 170ZKV4-48 VTX Aluminum Rear Sprocket 48-Tooth

The Vortex 170ZKV4-48 is a 48-tooth aluminum rear sprocket designed as a high-performance upgrade over heavier OEM steel sprockets. Engineered by Vortex Racing — a U.S.-based manufacturer with a long track record in road racing and motocross — this sprocket is precision CNC-machined from aerospace-grade 7075 T6 billet aluminum for an ideal balance of strength and reduced rotating mass.

Key Features:

• 48-Tooth Configuration — Optimized for gearing adjustments to suit your riding style and application
• 7075 T6 Billet Aluminum Construction — Aerospace-grade alloy delivers exceptional strength while significantly reducing weight compared to stock steel sprockets
• CNC-Machined to Tight Tolerances — Ensures precise concentricity and accurate chain engagement, minimizing wear on both the sprocket and chain
• Lightening Holes — Strategically placed cutouts further reduce rotating mass for improved throttle response and acceleration
• Anodized Finish — Provides corrosion resistance and a clean, performance-ready appearance
• Unique Tooth Profile — Vortex's proprietary tooth geometry promotes smooth chain engagement and extended sprocket longevity
• Made in the USA by Vortex Racing

Upgrading to the Vortex 170ZKV4-48 aluminum rear sprocket reduces drivetrain rotating mass, resulting in improved acceleration, sharper throttle response, and more responsive handling. Vortex sprockets are race-proven by top professional teams worldwide and built to meet the demands of both track and street riders.
