The top photo is a valiant attempt, BUT the motor IS a Honda, and such in my view, is pretty much a styling exercise and not really a Vincent.
Now the lower photos.....OH YEAH, MAMA. Now that's NICE. It reminds me of an Egli Vincent, the Swiss engineer's creation that actually sold fairly well in the '70s-'90s for a small concerns' product. He designed a new frame for that beautiful motor and attached modern(for that time-period) suspension parts to it. It was always near the top of my "To Get List" when I win that Power Ball thing.
Here in So.Cal, I still see a few old Vincents and the occasional Egli version, out and about, every once in a while. I always admire guys who actually ride them and don't just "store them for posterity". A certain present host of the "Tonight Show" often shows up Sunday mornings at the Rock Store on one. Mr.Leno has a very rare early version, a Series I from the late '30s, and a few later versions that he just loves talkin' about AND riding.
