Im looking into getting an outlander XMR. Now i know this version is MEANT for the mud. But im not into going in mud holes. Just puddles, rivers, rocks and trail riding. I personally love the look of the xmrs and i want that one. Im stuck between if i should get a 650 or if the 570 will be good enough? im male about 180 pounds. and might sometimes have a friend on the back with me. i take it the 850 and 1000s are just ridiculous and not really needed for what im doing with it? i do like speed though..
