A Kaw. 750 would be a lot like my 650, just a bigger motor. The power steering would be good, mine does steer hard unless I am moving. Kind of like old vehicles before power steering. I imagine the Bombardier 650 is much the same too. They used to sell a switch and wires for about $100 to convert Honda 4WD's that did not have the 4WD on/off switch. Maybe they sell those for Bombardier too. I hardly ever have mine in 4WD, I expect it would steer harder if it was on.
Is Pulaskiville near Pulaski? My g-g-grandfather is buried somewhere in Mercer Co, WVA, not too far from Pulaski, VA. There are some bigger mountains near there, an ATV would be the ticket if I had to climb them. Beautiful country.
