Could always go this route with the early 749/999 arm

Whats the difference between the black and grey swing arms other than the obvious !

Quite a bit besides the colour and the price

Have a look at these two on Ebay you can see they are very different

So presumably the black swinger is vastly superior in the handling dept. due to icreased stiffness ect .
Is £500 the going rate ?

I'm sure its more in the aesthetics the grey one is cast and is very stiff, whereas the black is a fabrication. I would think you would need to be Carlos Checa's team mate to notice any difference in handling between the two of them. :D

£500 is the upper end of the price range I have seen them with Buy it Now for £350

Well i am not Calos's team mate (i failed at the first audition ) but is there any advantage to the later black swinger ? The grey (which is on my recently purchase 999s ) looks a robust bit of kit .

I race in the Desmodue series, I also don't set the world alight. My 749 has its grey, (painted black) swingarm in and its fine. :D

On the back of that, how do you get bobbins to attach to the front, been really struggling on the front with a crap front paddock stand.......

Can you fit some bobbin mounts to my swing arm ghost? You're not exactly busy?!!
