I put down for one of those new ZX-4RR (400cc inline-4) bikes today. It revs over 15k, is rbw and has both qs+ab, and weighs 41 lbs less. Not sure if I will sell the CBR650R later or not, it's a good street bike, I've enjoyed it. Anyone else thinking the same? It's obviously not a straight trade, CBR has more torque, and more heft can be a comfort bonus flying down the freeway. CBR looks better, I never really cared much for the latest Kawasaki headlight design language.
