If you want to take them on the freeway, I recommend a Vespa 250, the luxury high-end scooter. It’s fast, great shocks and great brakes, much bigger wheels.
I have a vintage Vespa 150 and top speed on that is 45, so no freeway for me. Still great. Took it from my place in UTC to Motorsport and from there went on a rally along the coast to Oceanside and back home on a tank (1 1/2 gallon) w/gas left over.
Used to have a Vespa LX 150 and took it on the freeway once. It goes about 65-70. But it was scary. Even slightly wobbly (grooves in road)
I’m more comfortable on streets. (maybe a girl thing)
