The Honda 750 4 cyl was one of the best kept industrial secrets ever it blind sided Kawasaki which had a wooden mock up of the Z1 and it took them back a bit it also made the release date of the 900 Z1 stagnate for a bit whilst they digested the Honda I should imagine they had an employee buy one so they could evaluate it.
As the 500 Mach III's and the 750 H2's were lethal in a straight line not so good with cornering, in late 1976 I rode a fully worked H2 with the view of racing it after looking at the beam of the headlight pointing skywards I took it back. And proceeded to shelve the boy racer as I rode my 1976 Z900 home.
As a footer Kawasaki have announced they have a fire breather for the street next year 2019 a 243Hp monster which will probably smoke the Panigale V4's and maybe the BMW HP4's it is getting to the stage where the rider is the limiting factor for these bikes even with all their electronic aids and believe me they have plenty.
With my new bike my physical capabilities of hanging on at full power acceleration is the limiting factor as thats what allot of the test riders have said about Ducati's V4 your struggling to hold onto the grips under full dynamic power. Gad's have to give it a go once or twice just to see what its all about I just had a medical with a grip test so at 63Kg's & 62Kg's respectively I should be right..........
