Supersprox CST1441131 Front Countershaft Sprocket Steel Sprockets - 13-Tooth

The Supersprox CST-1441-13-1 is a 13-tooth steel front countershaft sprocket engineered for demanding motorcycle applications. Built to factory racing team specifications, this sprocket delivers a superior balance of performance and longevity over standard OEM and budget replacement options.

Key Features:

• SCM-435 Ni-Chrome Molybdenum steel construction — carbon-free, low-corrosion alloy with zero breaking risk and extended service life
• Ultra-hard surface layer (0.5mm) — reduces friction to minimize power loss caused by chain drag
• Case-hardened surface — maximizes water and corrosion resistance for all-weather riding
• Low carbon core — refined internal structure prevents tooth breakage under heavy load, unlike cheap C-45 sprockets
• Fully lightened with radial holes — reduces rotating mass for improved throttle response
• Grooved teeth — allows fast dirt removal to maximize sprocket and chain life in off-road and street applications
• Exclusive dual-zinc (2xZink) anti-corrosion black finish — factory styling with long-lasting protection

The Supersprox CST-1441-13-1 is a direct-fit replacement front sprocket manufactured to real factory team specifications. Its combination of hardened steel construction and precision engineering makes it one of the lightest and most durable steel countershaft sprockets available.
