I've seen post like this somewhere thought it might be fun to have one here..

Please don't post yamaha big bear 350 couldnt even turn 28 inch tires it sucked..

Realistic reasons they were the worst LOL

Mine was a 2003 prairie 650 thing was a total nightmare EVERYTHING!
second was a 06 brute force same deal..

 

Yamoto Tyhpoon. Yes they spelled it like that. Carb. wouldn't stay adjusted. Sold it to someone who was friendly with a mechanic.

 

2007 honda rubicon .....Ate shift angle sensor every 166 kms ...... Honda Canada could not figure it out ...So they bought it back !!!!!!

 

2005 King Quad 700-
chronic sensor issues with the carb, gage would always blank out- and bent 3 tie rods in one month with stock and oversized tires on pretty tame trails.

minor issues but- I know, but the sensor thing was a total PITA!!!

 

2000 Trailblazer. It just didn't have enough power.

 

97 scrambler 400. The oil injector line came off & the motor blew when it was 3 hours old.... things went downhill from there.

 

DS250 I bought to replace the Trailblazer the wife had. When you're wife tells you it's too slow, you know there's a problem.

 

Worst quad I have never owned is not having a quad at all LOL

 

yeah Dodge57hemi, thats worst than havin two modded quads/too small a backyard/can't get to a riding place,,,,,,,,,,,,,,,,,

 

I've only had three, but I wouldn't call any of them 'the worst', they were all good for what they were.

Had a big bear 350. It was rugged, tough. Rode like a go-kart, brutally stiff, gc was low so it got stuck. Nature of the beast with a solid rear axle utility quad.

Followed that on with a Cat 500, still have it 8 years later, it's still going strong. No failures, well nothing I didn't cause. Snapped the end off an axle, but that was my own stupidity for trying to goose it over a log with a loaded trailer behind.

Now have a Cat 400 TRV. Bought it cheap with a 'blown engine', turned out to be a stretched cam chain. Terrific machine, comfy, goes anywhere, a bit down on power but the price was right. With that long wheelbase, it climbs, well, like a cat. Wish it had a bigger engine, but I don't blame the quad for that, I blame my all too small bank account.

Well, I did have a dirt bike I just hated, darn thing kept trying to kill me. Yamaha YZ490. Way too much power for dodging trees in the woods, and I broke a toe trying to kick start it, when my foot slipped off the kick starter and jammed on the foot peg. The power was unreal, but there was always something wrong with it, and getting it started was like kicking a bear out of hibernation. If you weren't careful, it would turn around and bite you - hard.
