Does anybody have any information or pictures on the 1991 ATK 601 quad? It used a 600cc Rotax 4-stroke engine and it looked simaler to a trx250R chassis. Anyways, if anybody has any info or pics, then please ehlp me out.

 

Here are some pics and specs on a '97 or '98 prototype ATK605.

I actually got to see one of these things race at the ice races last sunday! There was also two DS650s racing there. The ATK quad I got to see was a ATK Rotax 604 in a LoneStar trx250R chassis.
I even got it on tape cause i took my video camera with me. it was pretty cool.
