In my formative years there were some truly flawed motorcycles around. I know 'cause I owned a few of them and worked on most of the others. Probably the worst street bike I ever owned was a 450 Ducati. While the bike has since become somewhat collectible, at least amongst the bevel-drive singles Ducati-cognoscenti, at the time it was just another oddball single cylinder motorcycle that no one wanted. As I recall, it came into our shop with a broken crankshaft. One of my cohorts snapped it up for a song, rebuilt it, then passed it along to me. It ran well enough, but needed at least an hour's maintenance for every two that it was ridden. I dumped it shortly after a critical electrical connection failed and left me by the side of the road, forcing me to miss a hot date. Two other doozys were my 1972 AJS 410 Stormer, a motocross bike that was tricky to start, difficult to keep running, and had a penchant for breaking frames that still boggles my mind. My 1967 BSA 250 Starfire was a pretty bike and truthfully, despite an insanely high level of vibration, reasonably reliable, but it gave new meaning to the word "underpowered" and leaked oil like Captain Hazelwood was at the helm.
