JT SPROCKETS Steel Sprocket 1539 - 520 (Manufacturer Part No: JTF1539.15)

Output sprocket designed for riders looking for a reliable transmission part suitable for replacement or gearing changes. Built to JT Sprockets standards, this 15-tooth sprocket fits a 520 pitch chain and is particularly aimed at roadsters and street machines.

• Material: steel (high-strength SMC420 alloy)
• Number of teeth: 15
• Chain pitch: 520
• Machining: CNC for precise fit
• Type / version: 1539 - standard version

The SMC420 steel construction and CNC machining ensure a well-defined tooth profile geometry, essential for smooth interaction with the chain and the rear sprocket. Ideal for replacing a worn sprocket or slightly modifying the gearing to adapt engine response and handling in urban or highway conditions.

Common compatibilities (examples): KAWASAKI ELIMINATOR 500 SE (2025), KAWASAKI ELIMINATOR 500 (2025), KAWASAKI NINJA ZX-4RR (2025). Always check the exact part number of your original sprocket before ordering and replace chain and sprocket/rear sprocket in pairs if necessary to ensure even wear.
