does anybody remember how exciting and blisteringly fast the kawasaki z900 was in 1974?, well she has a very naughty grand daughter the h2 pictured is 613kw/ tonne, top speed is 110km/hr your honour, however her big sister is very wicked (h2r track only version) , with the standard variable speed supercharger wound up to 20psi (from the factory) and the road gear removed gives 1069kw/ tonne, last recorded top speed was 400kmh
