Rejoin or shorten a broken chain

A thrown chain strands you unless you carry a master link and a breaker — together they weigh less than 200 g.

What you need

  • Chain breaker
  • Clip-type master link (+ a half link)
  • Pliers
  • Rag and gloves

Steps

  1. 01Get the chain off the sprockets and inspect for bent side plates and damaged rollers, plus any damage to the cases and swingarm.
  2. 02Push out the pins of any damaged links with the breaker, removing the smallest number of links you can.
  3. 03Join the ends with the master link, clip facing so the closed end leads in the direction of travel.
  4. 04Squeeze the clip on with pliers and confirm it is properly seated in both grooves.
  5. 05Reset chain slack. If you shortened the chain, wind the adjusters forward — and accept the sprocket alignment is now compromised.
  6. 06Ride gently, avoid full-throttle loads, and check the clip at every stop.

Watch out

  • A shortened chain runs at the wrong tension and eats sprockets — replace it as soon as you can.
  • If the chain took the cases with it, check for oil loss before you ride anywhere.
