no question in my mind. the ac 650 it has the prairie 650 motor, 13 inches of ground clearence(stock) and great stock tires. If he dosent have that kind of money look at any of the smaller ac models. but if i was looking for a 4x4 right now i would wait for the new King Quad coming next summer.

 

Well Fellas somewhere in there you have to include the Honda Foreman 450 with 26" tires. I know it's only 7.7" of ground clearance but almost 9" with 26's. I have seen some impressive things in the mudbogs with these, it ain't fast or alot of ground clearance but it pulls through mud and slop with the best of them with a good set of mudders and at around $5200 it ain't bad!!
Most articles you read on them they call it a 50mph Tractor it does what you want it to do and goes where you want it to go with no problems it's just a little slow but reliable. It has a SUPER low first for LOTS of torque and also has selectible 2 wheel to 4 wheel drive.

Since the AC put the v-twin in with a independent susp. I would say the AC would be a hard one to beat!

 

At the Missouri state fair last summer they had a mud run and with over 30 quads in 4 out of the top wre all polaris sportsmans.

 

I love my Grizzly and still think it is the best ALL AROUND bike out, but for pure mud, the Sp700 with 28" outlaws and a lift is hard, if not impossible, to beat in the mud. It is a monster. go to climb ATV's site and look at some of their monster bikes! www.climbatv.com

 

Those are some of the coolest pics I've seen!!! That makes me want to buy a big ute as a second ride.....

 

cool pics specially the 700 with outlaws

 

Not made anymore but the old Suzuki KingQuad 300 4X4 was awesome in the mud with some good tires. But now days the Praire 700 would be my choice.

 

For being stock, you can't beat a Sportsman with the Good Year Rawhides. 11.25" of ground clearance and IRS.

This has been posted alot on other forums. It's hard to say ever one thinks driffent. But i would go for the 660 grizzly, sp700, or teh new artic cat 650.
