50mm USD radial Fork Question

[Royalratch]

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

Just checked my list of fork sizes...don't have the 2011 GSXr but here's some older ones.
Top BTM
K1 GSXR1000 50 54
K2/3 GSXR1000 50 54
K4/5 GSXR1000 50 54

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
