Emissions…. the 600 and 650 are pushing the same power these days, are they not.  but those 700 were a thing of beauty for top speed with that narrow track, but they lacked the lower end grunt that today’s engines have!

Whatever happened to 700cc engines? Always thought they were the sweet spot at 140/145 hp.   I wish Arctic Cat would put the F7 engine in a Catalyst. Loved that motor! Just fun!        

I appreciate the real world experience and information.... 105 is good   100 is not enough  

Just to throw a wrench into your purchasing search, my wife's 650 Polaris is shockingly quick!! Once the motor was broke in it really surprised me, I took it for a rip on the lake & hit 105 mph on the speedo pretty quick!! Just more food for thought, happy shopping!!!

600 is gone - and not too me.  Snooze you lose as they say. Sold while I was sitting on it Back to searching.   And to answer, I love the Catalyst - but I am also looking hard at/for a Polaris. It's Polaris and/or Cat. Whichever I can find that I like and the deal works is what it's going to be - if any.   I have all the time to find the right deal with having a capable sled to ride - it's older - but it still works.   that said, as i learned yesterday - sit on the fence too long and you'll be sitting there forever.
