Hi
I had the ZX12R for five years from new in 2001, until I got my first GS. I bought the ZX after having a ZZR1100, and it was head and shoulders above the old bike. I has several problems with the headlight relay sticking on, and a broken wire to the cooling fan.
Thoroughly enjoyed my time with it, and completed my longest single journey on it, the 780 miles (I think) from Andorra to home.
