I' m glad to see at least one other person with a Suzuki. I' ve got a ' 99 King Quad 300. It has independant rear suspension with sealed drive shafts which can' t slip and don' t wear out. High, low and super low ranges. Differential lock. I' ve got almost 3000 miles on it. It' s been through water almost to the seat and will climb hills like a mountain goat. I' ve dragged more 4wheelers out of the woods than deer. It' s never failed to crank (even when my daughter filled it with diesel fuel []) and I' ve never had to do a thing to it but change the oil. It is an excellent machine. The only thing I would ever change on it is the manual transmisssion. Electronic shift would be nice in some situations.

Things to look for.
1. Do not ever buy one with a chain or belt drive. I' ve dragged a ton of Polaris chain drives out. Make sure to get one with sealed rear drive shafts.
2. Make sure you have at least two ranges on the transmission.
3. Make sure you have differential lock.

Just something I' ve noticed.
The larger atv' s NEED 4WD. I can' t tell you how many of the larger 2WD' s I' ve seen get stuck in mud and steep inclines. 300 to 450 cc' s is plenty of power to do about anything as long as it has the low range transmission. If you do get stuck, the smaller machines are a whole lot easier to man handle. Mine has only been stuck once and that was when my daughter bottomed it out over a downed pine tree.

There are lots of good machines out there. Paying attention to the individual features and getting the ones you need for your type of use is the key.
