Brand new 1976 motoski spirit - same as the elan. went through many after that and ended up with elans over the last 5 years but modding the heck out of them now, comfy and fast.
2002 Arctic Cat ZR 800. Eventually had the engine swapped for a 900 after the 800 cooked. Also had the tunnel extended to work with a 144" track. Overall great starter sled!
1971 Yamaha 433cc SW. Bogie track-no suspension. Wieghed more than i did and could get up to 65mph on hard pack(scary but fun for a 12 year old!). Had high and low range shifter on chaincase. Was my dad's until he piled up the chaincase and parked it for years until i earned enough money to replace the gears and chain in 83. Thing was a tank except a tank doesnt get stuck as much! What a blast!
