Can't speak for the ZX12 but I can say they sure worked good on my old 900RR. Well worth the$$$$$ and what a different bike.
They were cheaper than going with Ohlins and the fork tubes remained stock looking. But if I had the money, Ohlins would be on my 12 right now.
I'D RIDE A HARLEY DAVIDSON
BUT I CAN'T PULL THE TRAILER
WITH MY KAWASAKI!!</p>
i have them on the 12, and I like them alot. I havent taken it to the track yet but i can tell already that it handles alot better. BTW...i have the gold valves and the springs and I`m going to get my rear shock rebuilt by them also...so I`ll let you know about that also..........but I think its worth it....
