I have

Guy came in with a Honda CBR250R, the little four bangers like you're talking about. They are screamers, I had the honor of taking it for a spin. I get to ride a lot of cool stuff at work

They wrap up nicely, very nimble. It's about the size of an FZR400, maybe a little smaller. Beautiful bikes if you know what you're looking at. Shame they didn't sell any in the US.
Next on my list is a Yamaha R7, just because they're so rare, and the Yamaha RZ500 we've got in the back rotting away, trying to talk Orion out of that gem
