The Magnum 325 was listed at the top of the 300-350 class utility quads, they are great for a 325cc quad! The Magnum line of quads by Polaris is a good line up, the have a solid rear axle (less travel then the independent rears) and are shaft drive. (From the belt drive tranny to the rear dif) The Polaris true four wheel drive works like a charm. If you will be doing a lot of water crossing, or will have the chance of the hubs being under water for long periods of time, I would keep some hub oil handy to change out if needed. (Takes only a hex head driver to change the oil)
If you read over the ownerÂ’s manual it will have everything you need to know in it. As for maintenance, Oil change at 50 miles, then again at 100, then every 50 miles there after. I like to keep my Polaris well greased, once a week for me if it is being used every day. Keep your air filter clean to. (I suggest getting a "pre filter" for it, that is a sock like thing you can put over the filter to keep very small particles of dust out) The newer Polaris ATV have a great belt drive in them, there is very lil slip at all in them, But to stay safe keep out of water that will go over your knees while riding! I have had one belt break on my Sportsman 500HO, and that was from a dumb kid trying to drive it like a race quad!! (He thought the hand brake was for the from brakes only and tried to do burn outs on it while I was not around)I like to keep a few items with me when I know I will be in some serious riding conditions, I keep a small tool set with me, (all metric) some tire plugs, a bottle of tire slime, (I would put some slime in the tires to start out with to) a small AC air compressor, A spark plug or two, and what ever else you think you might need.
I think that this quad will do what you need it to do, as long as you keep in mind of the lower horsepower, and you do your part as a rider.
