The Telaio Rossa frames were chromoloy.

Was that really unusual?  My SS owners manual says the frame is chromoly.  Seems a wide range of metals were cro mo.

I don't know about your SS, but Ducati does have a history of stating that their frames are Chromoly when they were in fact just regular mild steel. The first 200 V7 Sports came with the red frame and were definitely chromoly, which does make the more collectable.

That's sort of my point and the subject of a prior post that you replied to..

If Ducati is using steel that has chrome and molybdenum but is not 4130, then it is still technically a chromoly frame, no?  Does Guzzi claim it is a 4130 steel frame?

and then I found this"

QuoteDucati's use what they call ALS 450 tubing for their frames; this alloy is also known as Fe E 420 or E420M UNI 10296-1. ALS is common shorthand for alloy steel, and 450 is the factory's designation for this particularly complicated alloy. More corrosion-resistant than the familiar 4130 chrome moly (a.k.a. chromoly) variety, it's relatively easy to weld and has what engineers like to call "a high modulus of elasticity," making it more durable in a tip-over. ALS 450 debuted in the '95 916's steel-trellis skeleton, and is also employed on the Desmosedici RR, using a different diameter to maintain rigidity without increasing wall thickness.

4130 CrMo is definitely a different beast.
It has more carbon content than 450, less Moly, and less Chromium. CrMo 4130 is easier to machine, but compared to 450 has much less corrosion resistance. 450 is a Stainless alloy, and by the looks of it not commonly used in the US. Its for "when austenitics aren't strong enough and martensitics do not provide enough corrosion resistance, there is custom 450 steel."

Having a "Sport"-labelled Guzzi kinda reminds me of having a hybrid SUV.

Ducatiz, where did you find this and how authoritative was the source?

It is a very interesting comment and at one point I looked around for info on Ducati's ALS450 and never came up with anything like it.

I had concluded it was a fancy name for a nothing-special material, dreamed up by Ducati's PR department.

Would be very happy to revise that conclusion.  

Edit: okay, you got it from a motorcyclist online article, as posted in the other thread you cited above. And I'm OT, sorry.

Tricolore Nero paint job on Superleggera.  Hubba, hubba!
