How to Count Motorcycle Chain Length

A motorcycle chain transfer power from the engine to the rear wheel.

A correctly sized motorcycle chain transfers the power from the transmission to the sprocket without failing under power. When put under the strain of acceleration, a loose chain will come off the wheel sprocket, and a chain with excessive tension may snap. The amount of links in a chain determines the chain length. Counting the links correctly -- without double-counting or missing a link -- is key to installing the correct chain for your motorcycle.

Things You'll Need

• Cardboard
• Center stand
• Brake cleaner
• Rag
• Marker

Instructions

1. Shift the motorcycle into neutral.

2. Place cardboard on the floor of your work area. Push the motorcycle onto the cardboard. Set the motorcycle on a center stand. Reset the motorcycle if it does not sit steady in the stand.

3. Spray brake cleaner on the motorcycle chain. Wipe the chain with a rag to remove built up grease.

4. Write a "1" on the front of one motorcycle chain link. Spin the rear wheel of the motorcycle. Count and mark each chain link until the chain returns to the "1."

5. Write down the number of links in the chain. Recount the number of chain links a second time to confirm the number.

6. Remove the motorcycle from the center stand.
