I went from a K1 SVS to a K5-GSXR 750, my other half has K5 pointy SVS which I've put a few miles on.

Pillion - Liz says imy GSXR is the most uncomfortable bike shes been pillion on

Rider - Its heavier on the wrist, the seat is higher and you sit more over the front of the bike. But its for me much more comfortable than my SV ever was.

I've ridden a K6-GSXR 600 as well. TBH theres b*gger all difference between the K5 and K6 models. I dont know about the later models, But IIRC its mainly cosmetic changes from the K6 onwards, althought I think the K9 has one of those power map buttons and I'm pretty sure the K6 onwards have a gear indicator which the K5's dont have.

The only way your going to know is to test ride a K5 and see how you get on, but you wont be disappointed.
