Ever seen a Kawasaki W650?It's a clone of the Triumph made around '98-00 but very few were imported into the US.
Bengt, I think you might have identified a mystery bike I saw Saturday, parked across the street from our daughter's apartment in Philly. It got my attention because from a distance, the tank and general configuration (side) looked (to my bad eyes) like a toaster-tank airhead. Another slight resemblance is that the crank bearing covers protrude more than usual for a vertical twin, and are the correct general shape and color, to trick a quick glance into the conclusion that it's a boxer (rather than a transverse-crank parallel). The only identifier I could find on the bike was "W650" (on the side covers, I think, but I can't recall for sure).
It's a beauty! Chrome fenders, nice lines. When I got closer, I saw that the tank looks more like a Triumph with knee pads, rather than a toaster Beemer.
Next trip to Philly (probably this Saturday), I'll try to remember to take a digital camera & try to get a shot (if it's parked there again).
