I find this bike extremely cool, but can't explain exactly why. It kinda reminds me of an early ('40s-'50s) hot rod, somehow (maybe it's the stance, wheels, big-n-little tires). The color scheme reminds me of an old Oliver tractor that I spent some long days in the saddle of as a kid, a model 66 Row-Crop. I'm usually not a fan of patina but this thing just looks right and it would be a shame to repaint it or do anything drastic, cosmetically, IMO. I do think a distressed brown leather seat might look good on it, odd since I usually don't like seats that aren't black, and that headlight looks like it could use a slight adjustment, unless you're going to be hunting raccoons from the saddle. I assume this bike is quite rare. I live in an area (SE VA) where all minibikes are quite rare (34 years here and don't think I've seen a vintage American minibike in person). I've been checking the local (Norfolk) CL daily for 2 years; on the extremely rare occasion that a vintage mini is listed, it's been molested and/or it's a rust bucket and/or the price is crazy and/or it's something I don't desire. January of last year, a Rupp Roadster (or very similar model) in Norfolk, totally encrusted in rust, sold for $3,000 (I should say I assume it sold as it was only listed for a few days). Now, there is a nice looking restored Roadster listed in Richmond for $5,800. I don't remember seeing any other Rupps between those two. What I'm leading up to is that, while I understand that Rupps are popular, your Twister must be much more rare (a lot cooler, too, IMO). If a nice one somehow came up for sale around here, I imagine the seller would be asking several thousand for it. I've checked this thread every day since the first post because I like this bike so much. I've been rambling and I'll stop, now. Anyway, great bike, please don't screw it up.!
