50mm USD radial Fork Question

I've got these forks from a 2006 Ninja ZX6R.
My callipers measure the clamp diameters at 50mm top and 52mm (52.12mm)at the bottom. Is this correct?
As I want to change them for a slightly different set from a 2011 GSXR but the seller says the bottom clamp diameter is 53mm.
Anyone shine a light?[/img]

Sounds about right...the bigger the bike, they like to make the forks thicker...for bragging right I guess.
I'm fitting a set of Superduke forks to mine and they measure 60mm

Damn.
So they do appear to change from by a few mm here and there.
I assume these forks are all made bu Showa for all the different Jap makers - why change the leg diameter? Some of the GSXR forsk are even 43mm at the clamp.
Aaarrgghh.

This might help.......
I originally found this on the oldskoolperformance site, although the chart I have posted is an updated version.

Thanks dude.
No confirmation on 05/06 ZX6R fork diameters tho.
Maybe my digital calipers are not accurate? Doubt that tho...

Hi Ratch, I thought you had it all sorted with those nice yokes, why do you want to change to the Suzuki forks? Jim
