Renthal 438-520-12GP Steel Front Countershaft Sprocket 12T 520 Chain

The Renthal 438-520-12GP is a 12-tooth front countershaft sprocket designed for 520-pitch chain applications on motocross and off-road motorcycles. Built to Renthal's exacting standards, this sprocket delivers reliable performance under demanding race and trail conditions.

Renthal front sprockets are manufactured from a specially developed nickel-chrome-molybdenum steel that is case hardened and core refined to provide the ultimate combination of surface hardness and core toughness — resisting wear on the teeth while maintaining structural integrity throughout the sprocket body.

Key Features:

• 12-tooth, 520-pitch front countershaft sprocket
• Nickel-chrome-molybdenum steel construction — case hardened for maximum wear resistance
• Self-cleaning mud grooves between every tooth on both sides to prevent dirt and debris buildup
• Precision CNC machined to extremely tight tolerances for accurate fit and smooth chain engagement
• Natural steel finish
• Sold individually (quantity of 1)

The Renthal 438-520-12GP is a direct-fit replacement countershaft sprocket that pairs with any standard 520-pitch drive chain. Its smaller 12-tooth count is ideal for riders seeking increased low-speed torque and improved control on technical terrain.
