My left hand makes riding anything with a clutch difficult. At the office, I keep a small 150 cc Kymco scooter. It will do 60 mph tops, has a windshield and an extra carry box on the back and is automatic. It's great to run around town on. You can park in alleys, beside buildings, etc.
Several manufacturers make bigger ones. Kymco is a big company in Taiwan. Sym is the other. They make a good portion of the best two wheelers in the world. The biggest engine SYM makes is a 250cc. It has an 80 plus MPH top end but is a little sluggish on the take-off. Kymco makes a 500 cc. I tried the SYM out yesterday and will try the Kymco out this week-end.
Only thing: It's really HARD to be cool on a motor scooter! That is unless it's one of the older restored Cushmans I have.
