Bloody hell, not sure I'd want a ZX9R for a winter bike when it's cold and slippery out, they hit about 140rwhp with a decent slipon alone!
Can understand what they mean about being too good as well - must admit if I could afford it I'd probably keep my FZS 600 as a winter bike/commuter and then have my ZX9R for long distance riding and Sunday blasts!
