Polaris has both the 2S 600 and 4S 750 Turbo LXT sleds. 136" track, IQ chassis and can be either setup as a two-up, or you can remove the rear seat and install either an enclosed compartment or a luggage rack. All the parts integrate well and they're very easy to swap out.
No 800 though. And probably not 'agressive' enough if you normally ride one-up with 'da boys'.
Skidoo renagade not the x because you can add the 1 plus 1 seat, it has the 137" track like the 2up's do to give a better ride then short tracks. My 2 cents!
My riding buddy's wife says he can get a new sled as long as it has a rear seat for hauling the kids around. Suggestions? Looking for an aggressive sled but not a mountain sled. 800 cc Preferably one that you can add the seat when needed. Thanks.
