There were no significant changes for the RV in '78. It was to be the last year for the free air RV.

    "I've turned a few heads with that sled though. Nothing like the sound of that little mill winding out at say, -26 celsius. And the fact that I'm keeping up with much larger liquids has earned me a few "brownie points" too!

    In 1987, I took my little "baby" on the annual "DealerRun" and when we woke up in the morning it was so cold my rewind spring wouldn't pull the rope back in. A few of the dealers were sort of looking down their noses at me and my vintage sled. Well they got an eye opener when we hit the lake let me tell you!!! They just couldn't shake that little yellow rocket of their tail. I had to explain to all of them (dealers?) about power to weight and how a well tuned, stock RV is no slouch on a cold day. I think I gained a lot of respect from the Bombardier Corp. reps that were there too!!

1978 T'NT F/A **

Models 340

    The troublesome 440 T'NT Free Air was dropped from the line, and the last free air T'NT offered to the public was the 78 340. It had minor cosmetic changes from the 77 but was fundamentally the same machine.

1978 R/V Cross Country *****

    New cross-country racing regulations in 1978 limited engine output to a mere 45 bhp.  In 1977 a cross country R/V racer was fitted with a liquid cooled motor. This liquid 354 engine produced far in excess of what the new regulations called for so the trusty 345 free air unit was detuned a bit and the R/V CC was born. Under the guidance of Gerard Karpik the sled dominated the cross country racing circuit.
