Power wise, It reminds me of the 700's I had. Accelerates hard. The only thing I don't like is the narrowness of the seat front. That's personal preference. Maybe if I didn't ride the tank, and pulled my handlebars back, instead of so far forward, the seat would be a non issue. Fuel consumption is on par with my 850. I think the 650 could go down as a legendary motor for Polaris , like the original 700 BB has. As far as fuel goes, where I ride I always get 91 non ethy, pretty much from the same stations all the time in the last 20 plus years. No problems yet. Luck?
