Vortex 150ZR-31 Steel Rear Sprocket 31-Tooth

The Vortex 150ZR-31 is a 31-tooth steel rear sprocket built to Vortex Racing's exacting standards for street and performance motorcycle applications. Engineered from a carbon steel alloy formulated to Vortex specifications, this sprocket delivers outstanding durability and long service life compared to standard OEM replacements.

Key Features:

• 31-tooth rear sprocket for precise gearing adjustment
• Carbon steel alloy construction per Vortex specifications for superior strength
• Silver anodized or electro-plated satin black finish to prevent corrosion
• Vortex patented unique tooth design engineered to increase sprocket longevity
• Precision-manufactured for accurate fitment and quiet, smooth chain engagement

Steel rear sprockets like the 150ZR-31 are the preferred choice for street riders seeking maximum wear resistance and long service intervals. The corrosion-resistant finish protects the sprocket in all weather conditions. As with all Vortex sprockets, the chain pitch must match your existing drivetrain — always replace the front sprocket and chain simultaneously for optimal performance and even wear.
