Most disappointing bike you've owned?

I'll start. Here's mine. My Ducati 959 Panigale. I wanted to love it, but it's the least comfortable (I'm not saying I bought it for comfort) bike I've owned. It burns my legs after 30 minutes. It leaks oil. I've had the entire gasket system replaced on the clutch. Other bikes I've owned that were more enjoyable and way more comfortable, Ninja 300 (my first bike), GXSR600, ZX-10r.

What's your most disappointing bike?
