An acquaintance of mine is about to get his SB8R on the road. He will need to replace the chain and sprockets. What are the sizes for front and rear sprockets?

Theres a sprocket code on the back sprocket, or take it off scan it and send it to the sprocket company.
The front is [standard GSXR 1100 W - ]don't go for a smaller front

I'm guessing you have antera wheels

Ignore this I read the title as SB6R

Bimota SB8R....they all came with Anteras didn't they? - Does that make a difference on the front sprocket as the engine is a TL1000 unit?

Yep as 2bims says, I recon the front would be standard TL1000 on the SB8R

Yes, they are Antera wheels. Stock TLR front is 17 teeth.

What about the rear?

Stock TLR rear is 39 teeth but on the TLR forum recommendations were to go with a higher tooth count, something like 41 or 42.

Partsbook for the SB8K lists a 17 on the front and 39 on the rear:

It even tells you its a 102 link chain.....nice of them....I do wish there was more consistency on the brochures and booklets...sometimes the Owners Handbooks give you the info you need...sprocket sizes, bulb wattage, etc....sometimes its the Workshop Manuals and sometimes its the Spare PArts Manual with the elusive information.....

I was searching through all 3 for one of my bikes for bulb wattage.....and there was nothing stated....Grrghhh….looked at the unit itself and it was formed into the moulding onto the back of it...not the most helpful location to contain the information
