I'm secure. But does size matter? (In old Vespas, I mean.)

    My 150cc Genuine Stella 2 stroke (made by LML in India) has a very low top speed of about 50 mph. And it cannot be ridden at full throttle for very long at the time without blowing the engine. A cruising speed of 40-45 is more like it. A 50cc Japanese scooter can do that. And my Zuma 125 and Vino 125 blow it away, hitting close to 60 top speed, and they can be ridden that way all day. The one place the Stella shines in in the mountains, where it's manual transmission allows you to keep the engine rpms up while climbing slow. It doesn't bog down, and beat up the engine. I don't know if a 150cc Vespa is any faster, but they are much higher quality, so you can run them at full throttle a lot longer.

    If it's stock, you might want to rejet it like it's a 1978 PX150, and change out the exhaust for anything else. Even the cheap exhausts you can buy on Ebay will allow it to breathe better than the stock pipe. It should get up to 55-60 and you won't have to worry about it seizing as much.

    When I put a Sito+, Piaggio air filter, and followed with a full carb rejet on my Stella, it seriously felt like a third more power on the butt dyno and the top speed went up as well. As a former Vino 125 owner (I owned both the Stella and Vino concurrently for a while) I'd say it went from accelerating as quickly as the Vino to a lower top speed to accelerating significantly more quickly to a comparable top speed. And it's done some 100+ mile days keeping up with 200-300cc modern scooters on 45-55mph roads, so durability has not suffered.

    JerryH, I'd highly suggest it. Under $150 all told and an hour or two's work and it's like a whole new bike - but really much more in-line with how it was originally designed. However it still thrives at 45mph or less, but remember, Vespas were designed for Italian cities, not American highways.

    I owned a 1966 Vespa 150cc that I bought used in 1968 and drove it 20,000 miles and then sold it about 2 years later. I wore out tires and cables and headlight bulbs and nothing else. The 6 volt headlight was a joke. I only crashed about 3 times and just minor slides and had only two breakdowns that caused problems. Once with a flat rear tire and once with a broken throttle cable. I used to drag the aluminum belly in the corners late at night in the residential subdivision just to piss off my girlfriend's parents. I was bad and the bike loved it. I can't say enough about the durability and reliably of the simple old 2-stroke engine. On my first long distance trip I discovered that I could ride it flat out, with full throttle on major roads at its maximum speed of 55 and could get 150mpg with mixed fuel.
    A totally awesome simple machine..

    Hey 568V8, I like your tale of scraping corners late night to piss off the GF's parents. Hilarious that an old Vespa can cause anybody a sleepless night! And you're right, after you get the thing up and running, it's just cables and tires and bulbs from there on in. Of course, mine's newer, so it may have more issues, but I doubt it.

    I actually had to pull the clutch this week to sort out a shifting issue (pulling away from stop, it wouldn't fully engage... like I was holding the clutch half way down). There was a mangled plate that needed replacing. After that, and a new cable swap just for good measure, the bike is as good as you can expect. Hope to take it out on Friday if it ever friggin stops raining/snowing/sleeting/shitting!

    And no, wanna bECO, I ain't gettin' a license! And no, it ain't that easy for me! I'm from the US, live in Africa, and bought this Vespa in Spain... Every time I'm in Wyoming, I try to get a license, but the DMV is only open 3 days a week, I don't have a bike there and would have to borrow, and I'm always swamped with family time. Hence the 125 in Spain (where lawmakers are too dumb to know a small cylinder bike is still a death trap) and my XR 400 in Africa (where there's no point having a license anyway, and every vehicle is a death trap).

    Fun times with red bikes.
