Refined but not re defined. The Hayabusa has gone through a myriad detail improvements over the last 10 years but it is still, at it’s core, a 2 wheel ballistic missile.Dont try pretending otherwise:-) Nothing looks like one or goes like one. Unique and immediately recognisable. Trade mark, "gas-flowed" body styling. Humungous horsepower. The king has new clothes..but it’s still the king. Hayabusa – Accept no substitute.
