Thought about building your own frame..?

Yeah, I was more asking whether Retro thought 4130, 6061 or other steel variant offered a more advantageous platform. It would be hard to make it from scratch and be "better" without lots of trial and error. Simply making a frame doesn't insure you've improved the original. Now, a modern tubing version of the original would be keen, but to what purpose? One can brace and alter the existing some without destroying its character or charm, and factory fitment.

I've toyed with this idea, I just haven't seen a great example of a new frame that screamed "I'm the one!" for a street bike.

I would keep original look but without stamped steel parts and ugly welds. I really like original look of the frame. I agree it gives character to bike...

You can use FEA software to design more rigid frame without to much trial and error thingy;)

You can not see good probably from pictures in my last post but i strengthen Central part of the frame... Where back bone tube is connected to side tubes. In original frame it is only stamped sheet connecting tubes there.

I LOVE the way you did the mono shock.  I haven't ruled out doing a mono shock on the 550 yet and I dig the way you integrated that connection into the frame there.

I actually know a guy here that builds frames but I haven't been game to ask him a price, everything is dear as poison here, I've spoken to Bakker in the Netherlands but I'm after a frame I can pass {at a distance} as stock and don't have to sell a kidney to buy....

Yep, Time to look into getting someone to bend some tubing and get it brazed here. Brent, do you have any idea of what type of steel is used for the rear engine mount section and foot peg mounts  brazed to the frame on Reynolds 531 frames..?

Brent can vouch for Denis Curtis at CMR.  He does build TZ replica frames and Honda Drixton frames for different displacements.  I bet he could do one for a 750, but I think the 550 engine is better balanced for race/track applications.
