Vortex 170-41 VTX Aluminum Rear Sprocket 41-Tooth

The Vortex 170-41 is a 41-tooth aluminum rear sprocket engineered for motorcycle riders seeking a lightweight, high-performance alternative to OEM steel sprockets. Manufactured in the USA, this sprocket is built to Vortex's exacting standards and is trusted by racers and performance street riders alike.

Key Features:

• 100% CNC manufactured in the USA for precise tolerances and consistent quality
• Specially formulated aluminum alloy per Vortex specifications for an optimal strength-to-weight ratio
• Silver anodized finish applied before cutting to prevent corrosion and deliver the iconic two-tone machined look
• Vortex patented tooth design for increased sprocket longevity and smooth chain engagement
• 41 teeth — suitable for fine-tuning gear ratios for improved acceleration or top-end performance
• Significantly lighter than steel counterparts, reducing rotational mass for a more responsive throttle feel

Aluminum sprockets like the Vortex 170-41 are the preferred choice for road racing, track days, and high-performance street applications where weight savings are a priority. For best results, keep the chain clean and properly tensioned — Vortex recommends inspecting and cleaning the chain and sprocket every 300–600 miles on street bikes to maximize service life.
