23 mph unless you have a kit on it. does that help?
He's riding a Vespa GT200 50cc.
How Fast Does a Vespa Go?It really depends on the displacement of the Scooter.For Modern Vespa Scooters:A stock 50cc Vespa will generally get about 65km/hA Stock 150 cc Vespa 98.0 km/h (60.9 mph)A Stock GT200 Vespa 119.0 km/h (73.9 mph)A Stock GTS250 122.0 km/h (75.8 mph) (remember the Torque is the Greatest Factor)A Stock GTS 300 123.0 km/h (75.8 mph) Again the torque of the scooter will outaccelerate its predecessor at any speed.
A vespa 150 cc super can do 50 mph, and a vespa 150 cc sprint can do 60 mph.
As far as performance, Vespa's 50 cc scooters are nothing special. They top out at 39 mph, which is not terrible, but is not quite as fast as Honda's cheaper metropolitan, which tops out at about 42 mph. Acceleration is average for a 50 cc scoter as well.
80 miles per hour
Vespa LX 50.... The Vespa excels in certain ways on the road. Its not fast, its not slow and its certainly not remotely sporty. It is however very secure on the road. This is what attracts some people to Vespa; people who prefer a bigger more solid feel will love it. The bike is certainly less affected by bumps and imperfections than smaller lighter scooters. It has also got a reasonable sized seat so will carry a pillion better than most 50cc scooters....
About 5km/h
45mph with no mods
