I heard you can fit another diff but I'm I'm wandering what from

You could get Mikeyboy to fit it for you...

Personally, I have both 18 and 17" wheels and have not really felt the need to do it... The bike still seems perfectly capable of lighting up the rear on damp tarmac...

But I could be tempted!

Problem is the technical stuff down hill.. spend a lot of time on the brakes.. I have a spare final drive but it's the same diff in it..
