So there you have it The official first IFS sleds.
When did the first IFS equipped sled appear?
Alouette had a IFS (Independent Front Suspension) on their factory twin-tracked sled in the early 70's and Polaris had a successful version on their RX-L oval racers in the mid 70's but the first successful consumer sled with a IFS was on the Arctic Cat Trail Cat in 1978. This low performance sled was relegated to also-ran when Polaris introduced the "modern" version in 1979 (1980 model) TX-L Indy. The term IFS is misleading since the old leaf spring sleds were actually independent also - they just didn't work worth a [email protected] The modern IFS, mislabeled, is actually dependent as the skis are connected (in most cases) with a sway bar.
Ron is correct, but I guess the real question is on what kind of sled? Racer? Production? or Other?Originally posted by RonTOF@Apr 19 2003, 02:59 PM
The Chapparell was the first to introduce the IFS in a factory race sled. This was in the very early 1970's.
Next would have been Gilles Villeneuve and the Alloute twin tracker, followed by his Skiroule racer 2 seasons later.
An independant named Gordon Roudolph wa very active in this area, he later was an advisor to Polaris with the RXL race sled.
The first CONSUMER trail sled equipped with IFS would have been the 1979 TRAIL CAT. I had one, and enjoyed it very much. These were followed by the Polaris Indy's and the Yamaha SRV.
