Went riding with a friend who has a Kaw ZZR 1200. We switched out bikes for a bit. Let me tell ya, that bike has some balz. Specs run it at a 10.1 quarter mile. Im here to tell ya.....GDamn what a powerhouse, Oh, I already said that. Incredible range of power. Beats the 1000RR in a quarter mile too. He was astonished at what the 600RR would do, we mixed it up on curves and straights. But, a couple of roll ons when I had the RR up around 10k, no pull away on the big Kaw. The outcome....he was very impressed with the RR. Said it was unbelievable it was a 600. Enjoyed the switch for a bit, but LOVE THE RR.
