Would anyone here have any idea where i could source this type of Aluminium  extrusion ?

Thanks for the links but I've already searched just about every catalogue I could find, I've come here as a last resort, I'm specifically after the very same extrusion in the picture I posted. I've seen it used on many swingarms but am struggling to find it....

Check here. They might be able to help

Dose anyone know what this type of extrusion is called ?  

Are you looking for stock of aluminum extrusion, or are you looking for an extrusion that has been bent and formed into the U-shape of a brace?

I'm looking for stock, I'll bend it myself, that picture I posted is from Webike and they want 303USD for what you see.  I just got off the phone to a major supplier here and they told me that it was probably a custom order, to use 6063 or 6060 T5, so I might just buy some 20mmx20mmx3mm radiused tube and mill a .5mm section out of it, I'm wanting that look. I always manage to make everything harder than it needs to be...!!!

I see.  You want that outside detail.  I would have thought that would be possible to find, but poking around the web it does look like it's a bit of a needle in a haystack.  Everything seems to be either plain square extrusions, 80/20 type functional shapes, or weird window trim.  It may be the case that someone somewhere has some stock of that, but I think you're right that it would probably take less time to machine plain square tubing yourself.

I can't help you with alloy choice, other than to say that 6061 does not bend well in a sheet metal brake.  The notes on the extrusions in the McMaster catalog say that 6063 and 6060 are both "easier to form than multipurpose 6061".

Good luck.

Yes, I thought i would be able to find it too. I know a guy that has a company that specialises in aerospace components, i'm going to ask him before I try and make it myself.
I like the way the brace looks with the detail....

 

The early GSXRs used a tube profile like that. I don't know if it would be cheaper to cut up a frame to get the tube but its an option. sub-frame tubes are 20 x 25, main down tubes are 27 x 30. this is a proprietary alloy similar to 7005.

 

Probably doesn't have the look your after, but what about Chrome Molly tubing?
That is what was used on my swingarm to brace it:

Funny you should say that, I actually have a 1988 GSXR1100J  Frame {last of the slabby's}, I won't be cutting it up though, they are starting to fetch good money....
