40 vs 420 roller chain

by Dr. Ansel Greenholt Published 4 years ago Updated 3 years ago

The pitch will be the same but a 420 motorcycle chain is narrower than an ANSI 40 or 41 chain, so no it won't fit. A 425 or 428 chain, however, would fit just fine. Yes, it WILL fit as the rollers are smaller although the pitch and roller width are the same. This just means that it may sit lower on the sprocket.

What's the difference between a 40 and 420 chain?

All will have a 1/2" pitch. We use the #420 chain the most out of these 3. It's not as wide (from side plate to side plate) as the #40 chain which helps to not slap your driven pulley or frame if it's in a tight fit. #420 will have more strength than the #41 chain because the side plates will be taller. #40 will be the beefiest chain in this class.
