Jayzus, TW, cut the kid some slack ...... It's okay, gasper, sometimes TW goes off his meds ...
Bottom line, though, TW is right. Most of the bikes you see are all the same underneath, with just repainted fairings.
A possibility here is to get one of those "blank" models for right now, and check around different sites to see who has the painted fairings for the company you want (i.e., Lucky Strike, Marlboro, Joe Camel, Repsol, etc.) Another possibility is, if you're talented with an airbrush, paint your own fairings. A lot of members on here have done just that, using anything from cheap spraypaint cans to professional paint sprayers.
Try checking on
ebay for the "company" fairings, or try looking at some of the pocketbike parts places to see if they have the fairings you want. Several manufacturers to check out would be Polini, Stamas, GRC, and Blata. Be forewarned, those fairings are going to cost a pretty penny, perhaps as much as the "blank" bike itself, and I don't think your budgeted $300 is going to cover it ....
Just out of curiousity, why mostly the cigarette companies?
