Returning to scooters after a 20+ absence, formerly owned an Allstate, and 2 Vespas.
Got this last fall, very nice features, including 12 inch wheels and disc brakes as standard equipment.
Originally 50cc, now upgraded to 72cc.
Also replaced airbox with UNI filter, and changed 6.7 gram rollers for 5.0 gram rollers. Changing the rollers moved maximum rpm from 6500 to 8000, providing a bit more power and acceleration.
Runs very well, top speed 47 mph indicated, 42 up a gentle grade, and 30 up a steep grade. At part throttle on level ground holds 40 mph at 7500 rpm. Almost zero vibration at any speed above idle.
I performed the upgrades myself, and am very pleased with the build quality of the engine. Castings and machine work appear very good, comparable to Japanese motorcycles I used to work, as well as my old Italian scooters.
Construction is similar to a classic Lambretta, with a tubular frame to which body panels are attached, and with a engine centrally located for better balance and handling. (The old Vespas had body panels all welded together for make a unibody, and the engine hung out on the right side).
Frame tubes are huge for such a small machine, although welds are not the most beautiful I've ever seen, perhaps because they knew they would be concealed by bodywork. This was also something which was sometimes seen on Japanese motorcycles of the 70's.
Have been trying to ride the scooter to work, weather permitting, looking forward to more fun with it.
