FrankLee - might not be a stock bike swing arm, b/c they're not kit vehicles, they're actually jig-built and assembled in house.

I saw somewhere a kit to mimic it though, that used a swingarm and part of the frame of just about any street bike you wanted to use. The whole vehicle would cost less than $2000 to build, not including the cost of the bike you hacked apart to build it.

So, since you could get a bike for ~$2000, and the kit costs ~$2000 to build, plus random pieces/screwups, etc... figure about ~$5000... vs. ~$50,000.

But, I'm going to try to find some information on exactly how strong the average bike swing arm is.
