Gidday, I'm searching for alternate rear sprockets for the 18 inch Suzuki rims. Found these on wemoto, but they only do down to a 44 tooth by the looks of it. I have a 36, 38 and 40 here, want a 42. Any other sources?

I dunno what your chain is (520 or 530?)

Here's a 42T for 530 chain. Appears to have the same hub dimensions as the one you posted.

If that doesn't suit, how about a blank 42T and machine it to suit your hub?
This one is 520, but 530 is available.

If Red has a range of sprockets suitable for the GSXR hub, he might be your quickest and easiest option.

If Red doesn't have 42T 530 for the Suzuki hub, they seem to be readily available elsewhere. I'm not sure why you're having difficulty finding them.

I may be looking at the wrong centre bolt hole configuration. Some sprocket suppliers say the GSXR has 5 holes on 100mm PCD, others say 5 holes on 140mm PCD. Maybe they changed the setup when they went from the old 6-spoke wheel to the later 3-spoke wheel. So, I'm not sure which one applies, but it doesn't really matter because 42T 530 sprockets are available for both types of sprocket centre.

Sprocket Pitch Diameter Formulas and Calculator

The sprocket pitch diameter is an imaginary circle through which the chain pin centers move around the sprocket. The pitch diameter is the fundamental design geometry that determines the size shape and form of the sprocket teeth dimensions.

This refers to the chain roller center diameter, but from the posts above it sounds like you are talking about the attachment bolt circle diameter.

What is PCD?

PCD = Pitch Circle Diameter. I dunno what it is in French, Paul. Possibly reverse anagram: DCP, diamètre du cercle primitif.

In general terms, it refers to the diameter of a circle on which any structure is regularly arranged. It can refer to bolt holes arranged in a circle, gear teeth, chain rollers as they lie around a sprocket, the stones in a stone circle, etc.

Here we're talking about the bolt holes through which the sprocket is bolted to the wheel (or more accurately the cush drive plate).
Not to be confused (in this case) with the chain roller centre diameter. That'll sort itself out with a specified number of teeth and the chain pitch.
