I had my '12DS in 3 times (at my selling dealer 200 miles away) for a leaking fork seal (the seal obviously wasn't the root cause). On the 3rd time Zero agreed to replace the forks.
A couple weeks later, I find oil on the floor next to the front wheel. I couldn't find the source at first, as the fork slider was clean. However, further investigation revealed that the (new) fork was leaking around the damping adjustment screw at the bottom. Fortunately a local dealer has opened, and I was able to drop the bike off after work. Got a call from them this week, and it must be dire this time, as Zero is sending another set of forks.
Zero has tried to help, and hopefully this time it will be fixed for good. The electrics haven't given me any problems. I also understand their decision to source "economical" non-electric components to keep the bike's price down, match their anticipated production volume, whatever. But I gotta say that Brammo's approach to component selection on the Empulse is looking pretty good to me right about now.
EDIT: Dealer called today. They got a fork from Zero, but it wasn't the proper one, and it was damaged to boot (not sure if that was in shipment or from the get-go). Sigh.
