I would imagine the performance is about the same as the Vino 125, which I have put over 15,000 enjoyable miles on.
The Zuma 125 should be faster than the Vino 125:
Zuma 125: 125cc, 4 valves, fuel injection, 10:1 compression ratio, forced air cooling
Vino 125: 124cc, 2 valves, 26mm Mikuni carb, 9.8:1 compression ratio, air cooling
The Zuma also has 12" tires vs. 10" for the Vino. The Zuma has a 220mm front brake disc vs. 180mm for the Vino.
But the Vino is about 25 lbs. lighter than the Zuma.
