Heavy Hitters

The bike on top is the mighty Kawasaki ZZR 1400 (also known as the Ninja ZX-14 in some markets). The one below it is the legendary Suzuki Hayabusa, or the GSX1300R. The Kawasaki, with its 187 horsepower, is about 15-20bhp up on the Suzuki. Both have 300km/h top speeds. Both accelerate like runaway rockets. Both can shred their rear tyres in one single day of hard riding. Both are insane, but which one is the maddest?
