I love the YFZ I'd love to ride that all day long...if my arms don't fall off.

 

for engine reliability WARRIOR i beet the CRAP outta that engine never broke nothing in it but i did break the frame and shocks!!!!

 

I'll say the DS650 or the DVX but that's just me cause i love them

 

I give my vote to the greatest, in my mind the lt 500r

 

well, the most revolutionary quads IMO would be the quadzilla, the 250r, the banshee, and the 400ex. as for my personal favorites, raptor or z of course

 

I'd have to say the quadzilla.

 

The quadzilla was definitely not the greatest quad of all time. The thing wasn't even very good at what it was made for...MX...the ONLY factory 2-stroke MX quad in my mind was the 250R...the zilla was revolutionary in one way: Awesome quickness right out of the crate.

other than that, the design is poor, reliability issues are poor even for a 2-stroke..its an ok drag engine, but not much beyond that

 

Today the best all around quad is the YFZ 450, it use to be the Warrior.

 

The TRX250R. It has the perfect combination of speed, agility, acceleration, and because it is a 2 stroke maintenance is simple - although you have to do it more often. Not to mention it is the most legendary and the most feard quad of all time.

 

i would definetly have to say the best quad of all time is the 250r
