Vortex 608-45 Silver 45-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 608-45 is a silver anodized, 45-tooth aluminum rear sprocket designed for 520-pitch chain applications. Built to race-grade standards, this sprocket is CNC-machined 100% in the USA from a specially formulated aluminum alloy developed to Vortex's own specifications, delivering an ideal balance of strength and reduced rotating mass.

Key Features:

• Lightweight aluminum construction — reduces rotating mass to improve throttle response and acceleration
• Strategically placed lightening holes — further reduce weight without compromising structural integrity
• Unique patented tooth geometry — Vortex's proprietary tooth profile promotes even chain wear and increases sprocket longevity
• Silver anodized finish — corrosion-resistant coating for lasting appearance and protection
• 100% CNC manufactured in the USA — precision machined to the tightest tolerances for consistent concentricity and fit
• 520 chain pitch — compatible with standard 520-pitch drive chains
• 45-tooth rear sprocket — provides increased low-end torque and quicker acceleration compared to lower tooth-count alternatives

Vortex Racing has been manufacturing championship-proven motorcycle components since 1995. Their sprockets are trusted by professional racers competing at the highest levels of AMA Superbike, AMA Sportbike, and international road racing. The 608-45 brings that same race-developed engineering to street and track riders seeking a direct OEM-style replacement or performance upgrade.
