My '82 Austro Daimler Alpina. It felt fine while it was my only bike, but when I got my Maruishi, I felt so much faster. The Alpina is a sport touring frame, but the front end geometry is floppy at all speeds. It requires rather large amounts of countersteer in turns, enough that you can't turn no-handed. The frame was reasonably stiff (far stiffer than my Maruishi, which I imagine rides like one of the aluminum Vitus frames), but when you really stomped on it, it just died. It wouldn't "spring back" and you had to countersteer HARD. It would twitch/snap in a heavy, loaded way.
