The measurements in the first picture are correct. Although not 100% accurate as its not exactly easy to measure a lumpy object with a straight object but I'd say thats more than usable and are the measurements that I'm using...

Oh and pictures:

Does your friend have some nice R model cartridge forks to fit then?

he wants the fully maxton'd up 29 fully adjustable jobbies from my track bike as I am fitting maxton'd up RVF forks.

As a point of interest, the CBR600F S-W used 41mm HMAS cartridge forks, although if what I am reading is correct they are adjustable for preload and rebound but not compression.
