I’ve now been driving my Z6000 for over two years. It’s still a great way to get around town but has had its share of problems. One brake fluid reservoir corroded and had to be replaced. I’ve had one tire replaced — the stock tires are sticky which results in great performance and not so great tread life.
I also had the seat replaced which wasn’t expensive but really didn’t last long in part because it was parked outside for extended periods. Some of the plastic cracked when they were servicing it and they replaced it (EMS) without charging me for what was quite a bit of labor.
In summary, I like the scooter but it’s been a bit of a headache to keep up with the issues that have arisen.
