Pretty sure that is the case with the Indy txl, but moto ski or one other company may have come out with a similar trailing arm setup around the same time. Bottom line is if you think trailing arm sled, you think Indy. The pro action came out in 97. A good 14 to 15 years after Polaris had the txl with Indy ifs.

Here is some reading... 1980 polaris txl

I remember them Indy's when they first came out.We were riding our regular style sleds and thought.."Holy Sh*t" when we passed one.Guys were saying they absorb all the bumps as we on our leaf springs bounced all over the place..lol

Yep, but only on race sleds and it was a very different setup compared to the Indy front end.

Take a look at my post above, the link has the chaparral picture.

Yea, that's cool. I've only ever seen a picture of one of those once. :-)
 
nothing is really new when it comes right down to it. take electronic reverse for example. Merc was doing that back in the 70's. there isnt much "new" tech, just new applications or ways of using it. my thoughts at least
 
cant say I have even heard of it, but if I am searching right it is a 2wd ohlins clutch?
or am I WAYYYYYY off base?
