July 14, 2007 The world’s fastest production motorcycle mantle is about to change hands again, returning to Suzuki due to the 2008 Hayabusa’s just announced specifications which should see it push past Kawasaki's ZX-14. The new 1340cc motor is 41cc bigger, and the three-ring, aluminum alloy forged slipper pistons have a compression ratio of 12.5:1, an increase over the current Hayabusa’s11.5:1 and is expected to deliver 12 percent more power, giving the Busa a rear wheel output of 175 to 180 bhp. The motor comes in two different bikes – the speed king Hayabusa and the hyper muscular B-King.
