chromoly vs what?
Steven H.
chromoly frames while the other models don't. What is it the non race
models use? cold rolled steel or what? I thought all motorcycles used
chromoly tubing but I'm obviously wrong.

The majority of Japanese bikes use mild steel. It's just as stiff as
chrome-moly, but not nearly strong. Translation: You need to design
heavier frames with mild steel to keep them from breaking.
ATK and KTM use chrome-moly. Try drilling or bending chrome-moly
& you'll see the difference. It is truely tough stuff. A frame properly
designed with chrome-moly can be stiffer and lighter than any aluminum
frame. The difficulty is in working with thin wall materials in high volume
manufacturing.

Gas Gas uses a chrome-moly steel frame, that is nickle plated.

Just as I thought. It seems everyone other than the Japanese uses an
alloy frame. I guess this explains why Jay is able to trash his XR so
easily. I suggest he get a "real" bike and see just how tough those NH
rocks really are.
ATK used to have nickle plated frames as well. I think the powder
coating is a better material. I'm amazed at how thick and durable PC
is.
Is the GG coating a bright or matte nickle? I recently learned that the
matte will be more ductile, making it a better coating for items that
see a lot of flexing (like Jay's frame).

My last bike, a '84 CanAm MX250LC had a chromoly frame - made from Reynolds
531 tubing (same as my old roadracing bicycle) in fact. You should've seen
that stuff evaporate when you hit it with an arc welder!!

I don't think 531 has any chrome in it, just manganese and molybdenum,
and the other stuff, carbon, etc.
Wasn't meant for welding, as you found out. The Brit's brazed
everything.

P.S. We did this 2 years ago, didn't we?

Most bikes are using tubed steel frames - the DRZ's use that chromoly stuff.
