Re: help me out
I bought a King Quad last August and agree that it's not the fastest machine. However, I live in Utah and ride in the mountains mostly. I use mine for hunting and taking me back to the mountain streams for some solitary fly fishing. I was new to ATV'ing and didn't want large, heavy machines to tow around. You don't need a speed demon for true off-road useage. The KingQuad transmission ranges can handle any climb. While climbing, you're (safely) only going 10-15 mph anyway. On flat dirt roads, the King Quad and QuadRunner (my other Suzuki) can cruise at 25 mph easily. Anything faster and the machine's steering gets a little unstable due to the radical off-road tires and short wheelbase.
If you aren't racing and want to enjoy the ride, expect to average 10 mph in the mountains. I just rode part of the Paiute ATV trail this past October, and that number is about right. If you participate in ATV Jamboree rides, they don't ride fast anyway. The idea is to enjoy the outdoors.
I've read that Polaris machines have had reliability problems. And there are something like 36 zerk fittings to grease when you go to lube them. I test rode a Sportsman before I bought the King Quad. It is big and fast and has a nice suspension. After you put it in 4x4 mode, the front wheels have to slip a certain amount before the machine is actually in 4 wheel mode. And the Polaris is big and heavy, and more expensive.
Although they aren't fancy, Suzuki has a reputation for reliability. One of the dealers in my area told me that he has cattle rancher type customers that buy ATVs from him. He said that the Suzuki machines are the only ones the ranchers haven't been able to break.
The other thing to consider is gas mileage. My smaller machines (300cc KingQuad, 250cc QuadRunner) can go 60 miles on a half a tank. If you plan to ride all day, no need to take extra gas. The bigger machines will require you to carry extra gas on long rides.
So I've given you my opinions, good and bad. Yeah, I'd like a little more power. But even my QuadRunner (250cc) takes me anywhere I want to go. I'm very pleased with my choices. Suzukis are reliable and easy to maintain. Adults or kids can ride them.
Good luck on your purchase whichever way you decide.
