Well, it was the first “Rider Forward” design…and Doo came up with the idea, and the name “Rev”(which is short for revolutionary.
Then the other 3 manufacturers started to go to that idea because it was such a radical/revolutionary idea, and it was so much better in every way than the low/sit back style that was used since the inception. So it was truly “revolutionary” in the snowmobile industry. But in the 22 years since, they’ve still improved massively, and are leaps and bounds ahead of that original 03 Rev.
