Those older sleds are very narrow and the lack of any kind of suspension makes them very unstable. They are great sleds to start on but riding a passanger is very difficult due to the stability, shorter seats, and lack of rear suspension. Not to say it can't be done, Ive been snowmobiling for the better part of 15 years on pre 1985 machines and managed until last year when I upgraded to a mid 90's! Whoa. I would go for it until you get your bearings, then upgrade to the more cantankerous machines later
