Step by step

  1. 1. Confirm the part fits

    Check the part against your exact model year and, where possible, your VIN. Match pitch and link count — 520, 525 or 530 with the OE link count

  2. 2. Prepare the bike

    Park on level ground, use paddock stands or a centre stand as required, let the engine cool, and disconnect the battery negative if you are touching wiring.

  3. 3. Remove the old part

    Work in the reverse of assembly order, bagging and labelling fasteners. Expect around 36 minutes here on a moderate job.

  4. 4. Fit the new part

    Common pitch: 520 / 525 / 530. Fit dry unless the manual calls for grease or thread-lock, and start every fastener by hand.

  5. 5. Torque and verify

    Torque every fastener to the manual value with a calibrated wrench. Never guess on brake, axle, or engine-mount hardware.

  6. 6. Test and re-check

    Do a stationary function check, then a slow test ride. Re-check fasteners and settings after the first 100 km.

Do it now if you see these

  • Tight spots when rotating the wheel through a full turn
  • Hooked or shark-finned sprocket teeth
  • Chain that lifts more than half a link off the rear sprocket
  • Slack that will not hold adjustment between rides

Check before you start

  • Match pitch and link count — 520, 525 or 530 with the OE link count
  • Change chain and both sprockets together as a kit
  • Set slack to the sticker figure with the bike on its wheels
  • Use an O-ring safe lube and clean before every re-lube

FAQ

How long does a motorcycle chain last?

A well-maintained X-ring chain runs 25,000-35,000 km. Neglected lubrication can cut that below 10,000 km.
