I have not owned a Kymco, but from what I have studied about them and learned from this forum and others is that they are bulletproof scooters. Except for the agility 125 (chinese), all the other kymcos are made at a top rate facility in Taiwan. I would rank them right under the japenese brands in reliability and workmanship.
Cortez (forum member) should chime in, he has owned ridden lots of scooters and currently has the big wheeled 300.
If i could get a kymco at the offer you are thinking of i would snatch one up in a heartbeat!
I have the zuma 125 and it will easily do 100 mile round trip, but 55mph max is all you are going to see on flat ground with neutral wind. Great little scooter in town and short trips.
