Gotta wonder, though, what your Eldo would do with both a turbo and nitrous. The problem with that gorgeous MG transverse V-twin is that you can't sub out another engine without obvious notice. But I do so very much wish a single someone would put "screaming, bada$$ performance" in an "old, laid-back, relaxed '50s cruiser-style" bike.
I LOVE the obvious, in your face, badarse look of the R3 (heck, I'm very likely to buy one, I like it so much), but I love sleepers, too. If I were Jay Leno and had his unlimited funds, only one of the things I'd build myself is a huge, from scratch, custom white or tiffany blue scooter, but with a Vespa front end on it, and a removeable wheelie bar, and with the stock little hard bags on the sides, and proceed to build a sub-10 second bike, and when not racing it, I'd ride around (in full hi-viz gear) looking for riders on the street who appear overly consumed with their manhoods, ride up with the stock "meepmeep" horn, do the dorkiest Mr. Bean wave possible, and then proceed to blow them off the road. And if you're also Jay Leno, you could probably even pay yourself back most if not all of the cost of the entire enterprise by doing a video series of other riders' reactions to you doing it to them, a la "Candid Camera". I know it's a one in a trillion shot the right minion would ever read it, but I may just have to email that idea to him to make myself feel better. "C'mon, man! We're talkin' comedy gold AND Leno's Garage, here!"
