When I bought this bike, the rear brake had seized. The clutch actuator seal failed, the bike did not idle that well, and the gearbox did not select as smoothly as I would have liked from 3-2-1 at lower revs.
The fork seals needed replacing and generally the stanchions suffer from pitting.
I have overhauled this bike and posted several pictures, which others may find useful. You can check this out on REDZED.PROBOARDS.COM.
Overall, I love the looks of these bikes, but once they hit 30,000 miles, the exhaust valve guides are likely to need replacing. Great bikes all the same, great Z1 looks, engine power at real road speeds, and the comfort.
Would you buy another motorcycle from this manufacturer? Yes
