now my whole thing is that my grandpa is pretty big guy and the two smaller ones are pull start and i dount think he can do that and the electric start ones are so expensive

 

If it's for your Gpa, I'd say go 250 Big Red. They are prolly the most expensive though with their cult like following.

If he's a little sportier (doesn't mind clutch and wants more suspension), go with the 250sx (my personal fav of the 4 you mention).

Cheapes will be the 185s. You should also be able to find a good 200s for cheap. They also made a 200m (electric start), but you'll pay more for it.

 

hey I have a 250sx and my father is a bigger guy and drives it just fine. it even seems to work better with him on it then me for somereason maybe better traction. But the main reason that i posted this is because. BIgblock you said 250sx has a clutch But mine doesn't and it still has the original engine/tranny in it. tranny has never been touch but they engine has been rebuild to a 300... am i sapose tohave a clutch
