As with everything, skill controls most of who out corners who as you know. That being said, an equally skilled 600/1000 rider will out corner you on a 14; no ifs ands or buts about it. However, the power on this thing is tremendous, and she will keep pulling all the way to the limiter without much effort.
I concour with x08. Let's not forget that the ZX-14 is at a hefty 265kg fully fuelled and is very wide compared to the much lighter, nimble and shorter wheelbase of litre bikes... Ask yourself first what are your needs and requirements. Only then can you decide which bike to go. Don't decide blindly my friend.
