awesome edit! really captured the fun atmosphere

haha I kept thinking of this comment today. I was at the PCA Riverside Enduro and the winner of Pro women went by the name of "Porky Springs". lol, no doubt her porn name.

Also, I think its a great comparison. Pro MTB's and Pro Moto'ers use PRODUCTION Frames! But both use factory unattainable suspsension, brakes, transmision/shifters ect. Also dirt bikes have to use the factory motor cases, although not much else is stock. Small stuff like bars, grips, ect is stock or at least avaible for purchase.

IMHO the main reason MTB's are relatively expensive is because of low production rates. There is only one size for a dirt bike (sadly i'm 6'4" so I look like a giant on mine) and only 5 brands. With so many brands/sizes/types of MTB's production rates are much much lower and therfore more expensive. Sadly its a tradeoff MTBers have, tons of options but pricey. If you need more evidince of this look at cars, they are ridiculous cheap for being huge and packed with tech. But hey i just answered my own question, I guess i am a little frustrated I can't afford a new carbon MTB!

how the fack do mountain bikes cost more than a brand new 450 dirt bike?!?

FYI you have to be a pro to ride supercross. Although I'll agree that there has to be some major differenes between moto/mtb, I'll argue that moto would have more demanding loads put on it, not only due to the extra weight but the extra speed. Those supercross tracks can get rough too, maybe not DH course rough but nothing to scough about. And then there is outdoor motocross...

Ok as a Materials Engineer the articles explanation sounds really confusing to me. jrhines and franky make a lot better explanation IMHO. I found a website that explains the "Heat Treatment of Aluminum-Base Alloys" pretty well: http://www.asminternational.org/portal/site/www/SubjectGuideItem/?vgnextoid=5c3655c96bd9d210VgnVCM100000621e010aRCRD Steps 1.Heating to the solution heat treating temperature and soaking long enough to put the alloy elements (i.e. not Aluminum) or compounds into solution 2.Quenching to room or some intermediate temperature (e.g., water) to keep the alloying elements or compounds in solution; essentially creating a supersaturated solid solution 3.Aging at either room temperature (natural aging) or a moderately elevated temperature (artificial aging) to cause the supersaturated solution to form a very fine precipitate in the aluminum matrix

He looked pretty stiff to me. roczen was on the ktm and throwing the bike around not danny.
