How to Add Links to a Motorcycle Chain

One of the most serious mistakes a rider can make is to add links to a motorcycle chain. The linkage is specifically designed for the drive system mounted on the bike. Adding linkage can cause a chain to stretch and fail in about 500 miles, versus the normal 20,000-mile lifespan of a chain. However, if you are looking to gain speed, you can change your gear ratios by installing a larger rear sprocket and longer chain. The process is basically the same for all types of motorcycles.

Things You'll Need

  • Chain breaker
  • Motorcycle jack
  • Motorcycle jack stand
  • Basic socket set
  • 2 blocks four-by-four wood
  • Rear sprocket
  • Cotter pin
  • Motorcycle chain
  • Master link

Instructions

    • 1

      Figure out your desired gear ratio. Divide the number of teeth on your rear sprocket by the number of teeth on your front sprocket. The higher your gear ratio, the faster your front sprocket will turn and your rpms will increase in each gear, giving you more power and speed. Make sure the rear sprocket you select will deliver the gear ratio you want.

      Locate the master link on your chain--the link that appears to have a double layer on one side. Clamp your chain breaker on the master link and compress the handles to separate the link. Pull the chain off the bike.

    • 3

      Jack the rear of the motorcycle up and place a jack stand under the center of the bike to support it.

    • 4

      Remove the cotter pin in the rear axle bolt. Use a socket set and wrench to remove the axle and tire from the motorcycle's frame.

    • 5

      Lay the tire on two blocks of wood so that it is held level off the ground. Remove the center nut that secures the rear sprocket to the hub. Lift the sprocket off the hub.

      Install the new rear sprocket. Slide the center hole over the exposed hub post. Tighten the bolt and re-install the tire onto the bike frame.

    • 7

      Feed you new chain over the front and rear sprocket. Pull tight, press the master link into position and "lock it" down.
