VORTEX STEEL FRONT SPROCKET 525-17T - 39-2910-17

The Vortex Racing Steel Front Sprocket is a direct-replacement countershaft sprocket manufactured to consistent dimensional tolerances. Designed for motorcycles running a 525-pitch chain, this 17-tooth unit is produced in steel for durability under sustained road and track use.

Vortex Racing is a US-based manufacturer with a long-standing reputation in the powersports aftermarket for sprocket and drive-component quality. This sprocket suits riders seeking a reliable OEM-style replacement or a gearing adjustment within a compatible 525-chain drivetrain.

• 525-pitch chain compatibility
• 17-tooth countershaft (front) sprocket
• Steel construction for strength and wear resistance
• Direct-replacement fitment design

Inspect the sprocket teeth for hooked, shark-fin or excessively worn profiles every service interval or approximately every 10,000 km — replace before this causes chain skip or accelerated chain wear.
Always replace the chain and rear sprocket at the same time if wear is evident; mixing a new sprocket with a worn chain shortens the life of both components.
Ensure the countershaft nut or retaining clip is torqued or seated to the motorcycle manufacturer's specification after fitment — an under-torqued front sprocket can walk off the shaft.
Lubricate the chain regularly according to your chain manufacturer's recommendation; adequate lubrication significantly reduces sprocket wear.
After installation, check chain tension and alignment against your motorcycle's service manual before riding.
Keep the sprocket and chain free of accumulated grime, road debris and corrosive materials such as brake fluid or battery acid; clean with a suitable chain-and-sprocket cleaner and a brush.
Store the sprocket in a dry environment away from moisture if not fitted immediately; light surface rust on steel can be removed before installation but deep pitting may compromise integrity.
