This bike was on The Kneeslider over a year ago but I had very little information on it at the time. I just noticed it turned up on eBay and I have to admit, I love this thing.
According to the description it has a Kraftek frame, a four speed Harley Davidson transmission, all powered by a 2.5 liter Alfa Romeo V6. There are six individual exhaust pipes, a pair of Weber downdrafts, with fork, discs and calipers from a Kawasaki ZXR750.
The owner says there's no charging system so, unless someone engineers one, it's a short range bar hopper. The whole thing needs some, ... what's the term, ... "finish work" to get it into daily rider status but it sure does look good!
