Front Sprocket - Steel With Rubber Cush 15T 525P

The RK Front Sprocket is a steel counter-shaft sprocket designed for motorcycles running a 525-pitch chain. With 15 teeth and an integrated rubber cushion between the sprocket body and carrier, it helps absorb drivetrain shock and reduce noise compared to a solid-mount sprocket.

RK is a respected Japanese manufacturer of motorcycle chains and sprockets, and this unit suits riders looking for a reliable OEM-style replacement or fitment upgrade on compatible 525-chain-equipped bikes.

• Steel construction for durability and wear resistance
• Rubber cush damper integrated to absorb drivetrain shock and vibration
• 15-tooth count for 525-pitch chain systems
• Compatible with 525-pitch drive chains
• OEM-style replacement design

Check the sprocket teeth regularly for wear — hooked, shark-fin shaped, or heavily worn teeth indicate the sprocket needs replacing.
Always replace the front sprocket together with the rear sprocket and the drive chain; mixing worn and new components accelerates wear on all parts.
Ensure correct chain tension after fitting, following the specific motorcycle manufacturer's specification.
Apply motorcycle chain lubricant to the chain at regular intervals, which also benefits sprocket longevity.
Inspect the rubber cush dampers for cracking, splitting or deterioration at each service; damaged rubbers can allow metal-to-metal contact and increase drivetrain shock.
When fitting, torque the counter-shaft sprocket retaining nut or bolt to the motorcycle manufacturer's specified torque value — do not estimate.
Clean the sprocket area with a suitable chain cleaner; avoid harsh solvents that could degrade the rubber cush components.
Store unmounted sprockets in a dry environment to prevent corrosion of the steel body.
