I've had:
Yamaha SRX600 - Grey Import cafe racer style single based on the XT motor. Unfortunately it had a "period" kick start, it took about 5-10 mins from cold to start the bloody thing, and after it started, you'd be sat there for ages trying to get your breath back!
GSX-R750 (J - '88) Slingshot - Had it for about 4 years, with a nice quiet Yoshimura system :D. Had to ride it like a stroker with it being a short stroke motor, and soooo flickable. Great fun though.
Triumph Daytona 900 - Pre injection model, after the Gixer, it felt like riding a Transit Van (and with ear plugs in, it sounded like one!), bloody quick though thanks to it's over-engineered long stroke triple. Until I managed to bury it into the rear quarter of a late 80's (uninsured) Ford Granada who was broadside in the road, 100m after a bend. Ouch.
