After not really feeling all that convinced with the Avanti SuperSport, I opted to take the other top-tank available in the US, a 2002 Tomos Targa LX. It's a nice bike, blue in color, and moves well for a stock machine. Tested a Targa with the BiTurbo exhaust, hi-performance spark plug and jetted carb, and wow, that one moves! For $100 (including labor), I think the upgrade is certainly worth it, and after a few months, it looks like I'll be making a visit back to my moped shop for the hop up.
I did already make one modification straight from the dealer: Removing the GARISH decals with the checkered flag, etc. But if you do this BE CAREFUL when it comes to removing them from plastic panels, as the paint left the panel while we were removing one of the stickers (so we placed it back on). The other side plastic panel was easily removed though.
I'll keep everyone posted on the bike, in case there are some seeking to get a new Tomos.
