I was in the Honda shop the other day to P/U a part. A salesman & I got talking, he showed me a Kawasaki NINJA (1300 I think) that's supercharged. Weights around 550#, 1/4 mile in the hi 8's. The supercharger is built right into the engine, a real clean looking deal, can't tell it's a supercharger. There's another one that's faster yet, special order. They also make a strict drag race model (not built for the high way) that's 89,000 bucks. Salesman was talking fast & really into this bike. I didn't retain all the exact numbers. I'm sure it's online.
