Whats a better motorcycle : kawasaki or suzuki?

I ride a Suzuki myself, a GS500F. It's been pretty reliable. Both of the bikes you're looking at are great for new riders to learn on; the Suzuki will be faster, but I expect the Kawasaki to get better mileage. The Kawasaki might also struggle to keep up on the freeway, while the Suzuki will have an easier time. I'd sit on both and see which one feels more comfortable, as that's one thing only you can decide for yourself.
