2001 Triumph Speed Triple. How can a motor so great be sooo boring? Not enough forward lean, heavy, totally linear characterless motor.
2007 BMW R1200GS. I loved to hate it. Does that count? Too big, too heavy, and even Ohlins couldn't get the suspension sorted the way I wanted it. Didn't stop me from putting 48k on one though.
1995 ZX11. Heavy long assed rocket ship. What a motor! And the rest of the bike just didn't fit me for crap.
I'm loving my Ducati Monster EVO - huge character, great looks, handles like a hummingbird on crack.
