When my wife wanted a bigger scooter after riding a Honda Metro (totally trouble free!) for a few years, I did the research, and did a test ride on a SYM HD200. We bought that scooter (It's a 2008). We have zero regrets. This thing can easily do freeways. It's a four valve water cooled motor, and it's a sweet running (compartative) powerhouse. Yes, it doesn't have a kick starter.But then, I understande the Vespas have a problem of cracking the engine cases if you use the kicker, and they are removing them from the fuel injected models, because, with FI if your battery is dead (which is why you are using the kicker) you can't use a kick start anyway. That's because you have to have battery current to operate the fuel pump before you start the engine.
I have seen leftover 2008 and 2009 HD200s for $2600 out the door.The 16 inch wheels are really nice handling too.We are getting in the 70s as far as gas mileage.It's just an awesome scooter. Just read a message from a couple that have two HD125s (same as the 200 but bored and/or stroked engiens) that just relaced the first belt at 26,000 miles. They said it was in such good shape that they kept it for a spare. I haven't needed any parts yet, but they say you can get parts out of Canada or Taiwan fro Scooter Assasins.
Nothing against Vespas.I like the S150. Just bought myself a new Kymco People 150 as it was a deal I couldn't refuse.
Good luck in your choice. I suggest you test ride an HD200 (and even the HD125 is pretty fast).
