Motorbike chain details
Question for those with bike knowledge (as I have none! )
What are the different specifications/sizes etc for bike chains, and how do they relate (if at all) to industrial chains?
I hear references to "520" chain and "530" chain, what the hell does that mean??????
I've tried a number of internet searches but all I get on the ludicrously slow connection here at work is total crap from the US of A instead of
actual answers!!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

"A motorcycle chain is the most common method used to connect and drive the rear wheel in a motorcycle. The others are belt drive and shaft
drive.
Chain size is in inches, the three digit number used to discribe the chain size is based on the "rule of eights". The first digit is for
chain pitch. This is the distance between the pins. The second and third digits combine for roller width, with a decimal point inserted between the
second and third digits.
For example, a 420 chain has a pitch of 4/8" = 1/2" (12.70mm) and a roller width of 2.0/8" = 1/4" (6.35mm).
A 525 chain (the size my bike uses) has a pitch of 5/8" (15.88mm) and a roller width of 2.5/8" (7.94mm).
A 530 chain has a pitch of 5/8" (15.88mm) and a roller width of 3.0/8" (9.52mm).
There are a number of chain sizes in use, and chain manufacturers may have slightly different specs for roller diameter, sprocket width, etc. But a
525 chain from one manufacturer will have the same pitch as a 520, 525, 530, or 532 chain from another and run smoothly on any 525 sprocket from any
manufacturer. "
