Vortex 144B-63 Silver 63-Tooth Rear Sprocket

The Vortex 144B-63 is a high-performance rear sprocket constructed from 7075 aircraft-grade aluminum, designed for sportbike applications. This silver 63-tooth rear sprocket offers exceptional durability and reduced rotational mass compared to steel alternatives.

Key Features:

• Precision machined construction for optimal fitment and performance
• Unique tooth design increases sprocket longevity
• Vortex patented sprocket design unlike any other sprocket
• Clear coating to help prevent oxidation
• Aerospace-grade aluminum provides optimal power transfer and reduced rotational mass
• 63-tooth configuration for modified gearing ratios

The 63-tooth count is larger than most stock applications, providing increased low-end torque and improved acceleration characteristics. Vortex sprockets are made from aerospace-grade aluminum, making them significantly lighter than steel counterparts while maintaining excellent strength and durability. Aluminum sprockets should have the chain cleaned and tensioned every 300-400 miles to maximize service life.
