I agree^^glad to hear you stayed with your 2010 Rancher 420. Even back in 04 the Rincon wasn't near the top for what you could get then. I applaud Honda for trying to keep with being different, but your Rancher is a good machine.
If the ride is what is bothering you I would suggest in investing in a good quality set of aftermarket shocks. Something like Works Performance AT steelers set up for your weight would make that machine night and day different over stock. Expensive,,,yes and no,,its worth it if you rode a machine that was set up like that and you want to keep it long term..You can even put the stockers back on when you wanted to sell it, and sell the shocks to someone else later on. It was my major complaint on my 420,,,it rode rough! Other than that it was a good atv. I still miss the feel of a gear quad sometimes. Just put it in 3rd and cruise is what I did most of the time.
