Welcome aboard @Gordon....right off the bat, like you already as that's my Dad's name...lol My oldest grandson had the Ninja 400...loved it--even did a trackday with it. He eventually sold it on....now rides my old XT 600 SuMo...couldn't be happier. I did a stint at a bike shop awhile back & had the opportunity to turn a few spanners on ZX6's...nice bikes, but the ergo's will eventually take a toll on your body. Pretty, Fast bikes are 1 thing, but there a fair amount of Ergo-correct options out there that will make for quite a load of happy 2-wheel miles. It'll be great to see what you end up with....
