Supersprox CST1586162 Front Countershaft Sprocket Steel Sprockets - 16-Tooth

The Supersprox CST-1586:16.2 is a 16-tooth front countershaft sprocket (also known as a drive sprocket or front sprocket) engineered to factory racing team specifications. Built from premium SCM-435 carbon-free steel with a carbon impregnation process, this sprocket delivers an exceptional combination of surface hardness and core toughness for long-lasting performance.

Key Features:

• SCM-435 Carbon-Free Steel Construction — Carbon impregnated for a refined core structure that resists tooth breakage, unlike lower-grade C-45 steel sprockets
• Ultra-Hard Surface Layer — Reduces friction and minimizes power loss caused by chain drag
• Fully Lightened with Radial Holes — Reduces rotating mass for improved throttle response and performance
• Grooved Teeth — Channels dirt and debris away from the chain interface, maximizing sprocket and chain service life
• 16 Teeth — Stock replacement tooth count for precise gear ratio retention
• Factory Team Specification — Manufactured by the company supplying factory teams in WSBK, MXGP, WEC, and Rally racing

Supersprox countershaft sprockets are a direct OEM-style replacement that meet or exceed original equipment standards for fit and function. Manufacturer part number: CST-1586:16.2.
