I am a big guy thinking of switching from a m1000 162 to a rev xp. Like my sled but wish it was about 100 lbs lighter. Any input on the two would be appreciated. Have rode a xp 2 3 years ago. I forgot what they ride like. I would look for one with a new engine. After the engine has been replaced, are they good to go or is it every 1000 miles they need a rebuild. Thanks
