fyi -- all is of my own opinion and experiences below.  Everyone's opinion may differ:

-----------------------------------------------------------------------------------


what about a 2-part frame like the older Elefants or SBKs?

main part out of cromo, seat/sub frame out of ti or alu for weight

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

What about that NCR titanium 1098 frame then.  And the ARC fab stuff too!

The Zo6's control arms holding up massive tire/brake combo's are made of aluminum alloy.  Hell, the 87 RX7 turbo car I used to play with has aluminum suspension arms in it, and plenty of those are tracked on a regular basis (or were back in the day).

What, like this?









Been working on this project for a while now w/my fabricator.  This is the first unit which is spoken for.

I'll be finishing it's installation onto an S2R frame next week and then will weigh it to compare and get the weight savings.

0.063" wall aluminum tubing.  Arc welded joints.  Heat-treated and then electro-polished for a nice finish.

Working up pricing on the kits now and there will be a shorter lower leg version available soon for the bikes w/rear-sets attached to the frame.  All of these will be only available for the ST-based frame bikes 2002 & up.

We're also working on a thicker-wall tubing unit which would be rated for a passenger, this one is for rider ONLY.

I am taking deposits on the first production batch right now.  I think there are 3 not yet spoken for but those are S*R frame bikes and rider ONLY.  (as shown above.)

...droool...

maybe sell it with a modified factory seat so it is monoposto only?

Keep us posted Stew.  I'd be interested in an aluminum sub-frame rated for a passenger.  How much?

Nice subframe Duck-Stew. In the next few weeks, I'm building one for my race monster. I'm hoping to loose at least 10 lbs. I plan to make a spare for crashes.

Stuart / Duck-Stew stumbled onto something awhile back in regard to a modification he did to a few customer bikes.  Tossing the S2R shock assembly away and using a SuperSport style mounted shock. (no linkage/rocker = less weight)  Forward mounted upper shock mount would allow a 100% replacement of the rear seat subframe then as well to remove more weight. (something you can't do with the strength required for the S2R upper shock mount)  Of course these mods require moderate fabrication but you can save 5-8lbs really fast.

Pricing to come shortly (and I'll quit thread-jacking this one make my own thread at that point...)

Also working on a more advanced version of that concept....    [evil]

Stew, thanks for sharing what you are working on.  You know you can jack any thread here any time you want.  Especially with something as cool as an aluminum sub-frame.  You are just humble.

Only by the amount (depth) in penetrates the surface I would think.

that's enough for crack propagation, I've seen limited data, but since it is prohibited in most of the specs we receive, I did not dig too deep.
