schwinn s500. i collect them. ive got about 6 of em. there the toughest scooter known to man, even in stock trim. ive been, underwater, 6 feet in the air, 35mph, offroad, in the mud. on those units. ive gotten 25mph out of a "stock" currie 500. i love em. i hvent gotten any of the rarer full suspention, or front suspention models, or the long wheelbase 36v s750. that one is a very hight milage one. i think it had 500+ by the wear in the motor. it is a 07 moel year, and its beat. ive had much nicer ones. im prolly gonna go orange metalflake. i like the schwinn red, but the paint is bad. it had a little bit of rust, but wasnt bad.
