Chain choice when fitting bandit wheel and swing arm GSX 1100


Recommended Posts

Chain sizes are easy to figure out

The first number is the pitch, the distance from pin to pin in 1/8"... so a 520 or 530 chain is 5/8" pitch, a 630 is 3/4" pitch and a 428 is 1/2" pitch

The next two numbers is the  sprocket thickness... a 530 is 3/8", 520 is 1/4, a 525 is 5/16

... but nothing governs the OUTSIDE dimensions... a 530 chain could be 1 1/8" wide (outside) for a cheapo Oring or as narrow as 0.8" for a DID HD Non Oring.

Modern 520 chains can be as strong as 630 chains of 1980. If I am changing chains I usually use a 520. My GS1000 has a 520, and I just converted the neighbor's  kid's 90cc ATV to 520... had the chain and sprockets on the shelf
