So I guess I'll give my two cents because I was in your position 6 months ago. I bought Honda because every Honda I have ever been around runs forever!!!!
Every Polaris I ever owned or used needed to be worked on constantly. My Yamaha's like Honda just keep going and going. But the 700 is my first SxS. I did no research and knew very little about SxS's! But the dealer had 1 700 deluxe coming in and didn't know when another one would arrive. So I put my money down and a few weeks latter I was the proud new owner $13,200 with roof and front windshield.
#1 did not have enough ground clearance for my style of ridding= bigger tiers 12"x27" and spring spacers.
#2 to narrow for rutted roads= wheel spacer.
#3 because of bigger tiers at around 6500 feet in elevation it did not have enough power to climb over even modestly rough terrain.= bigger tiers & wheels 14" x 28" so I could accommodate portals
#4 speedometer now screwed up reading 10 MPH fast = add speed health to fix speedo now shift points all F#@*ed up!
So my cheap ass did not want to dump 20k plus on a 1k or a Talion so now instead I'm pushing 30k for a 700?????????????
my advice would be go some place that rents SxS's and rent a few different types and ride them in that environment. Then think about the kind of area and style of ridding you will be or plan to be ridding in. Then come back and ask us all the questions you have and we will be much more helpful to you.
The people on hear are an Amazing resource as well as a wealth of knowledge.
I love to modify the crap out of everything I own but I am really kicking my own ass over this one. There is so much more to deciding what SxS is best for you than style and CC guess that's why there are so many different makes and model's
Good luck to you in your quest
