I sell both Yamaha and Suzuki. Both are great quads. Suzuki , has a little better and softer suspension. The grizzly is 4 " shorter in length, and a little quicker off the line , actually the grizz will whip the kq ,speed wise. A fellow above me made a very wise comment, NEITHER OF THESE QUADS SHOULD EVER HAVE TIRES INSTALLED LARGER THAN 25" PERIOD! NEVER! I know a million people on here will tell you differently , believe me I deal with these machines daily , put a set of maxxis 25' bighorns on and you will be surprised how well they look and fit. I love both quads I sell more suzukis , but the 05 finance is the reason for more Suzuki than Yamaha. I can give you one more fact! THE YAMAHA IS THE 2ND BEST SELLER IN THE WORLD ,AND WILL BE AROUND FOREVER. THE SUZUKI WON'T. FACT! Suzuki is 7th in sales the absolute bottom. Great quads, very poor marketing and not a single change going on a decade. 1000 dealers just got cut loose by Suzuki, people aren't buying kqs anymore. A lack of advertising by Suzuki has all but eliminated the kq. This is why they are so cheap. As dealers , Suzuki won't even tell us if there will be a change for 2015. They won't even tell us if the bankruptcy talk is rumor or fact. When we sit on these quads for a year at a time in our showrooms, paying 15,000 dollars a month in intrest , you would think that Suzuki would at least feed us some info. Like I said they are both good quads and even if Suzuki folds, the parts will be out ther for a long time. It breaks my heart that the Polaris out sells both 3 1/2 to one. I also sell Polaris which doesn't even compare to the quality of the other 2. But none the less we sell about 30 Polaris's a week and we work on 50 a week.
