I remember in the early seventies my dad was telling me that the ATC90 would float. I believe if it is light enough and the tires are big enough it will float. I can not picture a typical ATC250r floating upright easily, but I can picture an atc90 with stock baloon tires floating.

 

Every 3-wheeler I've seen dunked ended up floating upside down. LOL

Quads are too heavy......They sink.

 

i fell through a pond (winter) on a blaster and it floated upright but it would have flipped over if the ice wasnr there

 

Hate to bust your bubble Chris142, but you said quads do not float. Well the 95 King Quad I had floats just fine, along as it is in stock form. It will not float with rider after installing a winchbumper and winch, I have floated many a beaver pond that way. Even after the install of the winch and bumper the wheeler will float without me on it I took a wrong turn one evening and ended up crossing the wrong end of a pond and it was alot deeper then I imagined and the quad sucked water and it sank, but when I jumped off it came back to the surface and I swam and pulled the quad to the other side. Of course it sucked too much water in it and would not start so it was a very cold tow job{May black bear hunt} back to the truck. But you will find out some quads will float in certain situations just like 3 wheelers but I would not suggest running out to see if your quad will float as it could get expensive, I found out by accident and took advantage of it before I added heavy accessories to it.AlaskaBoy.

 

I grew up in the sweet spot of three wheeler times. I was 12 in 1982 and everyone I knew had a three wheeler. Honda’s would suck in water when it got to deep. They always said “the Yamaha would float”. I had a 225r or 250r shaft drive, and certainly went through the deepest swamps I could find. I was riding with a friend in a flooded gravel pit when the bottom dropped away. I probably weighed 80 lbs and it felt tippy. I just kept the gas on and it slowly crept forward about 10 yards across maybe 5 ft deep water. We were far from touching. I was scared it would capsize. The front was up and about 3-4 inches of the rear tires above water.
The air intake was always said to be up high. The whole tank and handle bars were above water. I climbed on the seat and I don’t think I got wet at all.
True story. For a small kid with good balance you can ride a stock Yamaha through as deep water as you want as long as you don’t flip it.

 

An early ATC (1969 to 1974) with balloon tires will float all day long upside down. Too unstable in upright position much less with a rider on board to stay upright.

 

WOW, that is incredible balance on your part. My hat is off to you good sir!
