Thats funny, my girlfriend's grandpa has probably the same year moto4, and pretty much the same back story, only this one still runs like a top! Probably the most fun you can have on four wheels, he even welded a shifter out of an old pickup onto the foot shifter to change gears by hand lol
They may only be 2wd,but they can pull a lot of weight and if you get it stuck just pick it up and move it...
