I picked the Kaw. I like the seating position and can ride it most of the day. I'm looking at going with a smaller bike because I'm getting more into the twistie riding. I ride with a couple of R1 and 929 owners and have swapped bikes. It seems like you only stay in one gear with the bigger bikes because the power is too much for for street riding with lots of turns. The 600s I rode it feels like you can shift up/down a litle before setting up for the next turn.
Personally my next bike will bne a twin. I never owned one but rode enough of my friends to know that will be my next bike. Hoping to go with Mille. The 916+996 seating just kills me. The Rc-51 is a close second but none of the dealers around here can keep them in stock. Seems like they are sold the same day they come in.
