Of course, I’m talking about the Kawasaki Z1 900 – to my mind the original ‘Superbike’ and an absolute legend of motorcycling. Now, well over 40 years later, not only have I ridden the all new ‘retro’ Z900 RS, I’ve also, finally, ridden the original – but not just any bloody original either – a hot-rodded “Croz” special that is just dripping in cool.
