Would there be a market for an aluminum frame?

A talented friend is thinking about fabricating aluminum frames for trellis-based performance motorcycles and has approached me about using my Brutale to 'clone' the frame. The objective would be to render a frame with improvements both in torsional rigidity, weight, and adjustment options (such as an Aprilia SV4).
Is there a market for improved frames?

Post Wow

I would like to see that, I have yet to see a Ally Trellis frame on a modern road bike, I have no idea how he would get the same strenght out of it.
Ti I could like, which often that I could afford one of those.

Thumbs down whoa!

OK, the MV has a chromoly trellis frame, don't know what its heat treated to but, you could take 4130 to 150k or more but i wouldn't ......keep the steel frame

yes, aluminum weighs 1/3rd of what steel does, but the modulus is 1/3 of steel.....so for equal strength it need to be 3 times as thick or increase the diameter

and aluminum work hardens too, thats why the radiators crack

Donsy forget Ti

I agree with Noel on this one,chrome moly is good stuff,it is strong,flexiable and can be made 1/3rd the size of alluminium to achieve the strengh.You only have to look at the Jap bikes with that ugly twin spar alloy frame,give me chrome moly any day,Mitch.

I think if he's that ambitious he should make titanium sub-frames.
Better chance of selling those to F4 y10+ guys who don't want passenger peg mount holes, and are looking everywhere to cut weight.

Reading the responses so far, people have assumed that your friend is attempting to fabricate an aluminium trellis type frame, where reading your post, it seems maybe this is not the case? Could you clarify if in fact he is looking at fabricating a aluminium cradle type frame as per the RSV4 or if in fact he is looking at creating a trellis frame out of Aluminium?

I think clarifying this will help, as I agree with the consensus here that it is a no go on an aluminium trellis frame, but would be an option on a cradle style frame and would open up those options you propose.

I don't think this would do anything for the looks of the bike (IMHO), but it would nevertheless be an interesting concept to see developed. If Alex (Alka) reads this, maybe he could photoshop this concept to see what it would look like!

I'm with Donsy though and would love to see a Ti frame, or should I say, I would love to be able to afford a Ti frame!
