My experience is the exact opposite. I had a 200 Duke that I used as a commuter for five years. Not one issue. Same with my 790 Duke, not one issue in nearly three years (a couple of minor things fixed at first service). Prior to the 790, I owned a number of BMs, the last being a 1200GSA. Compared to the BMs, the 790 is miles more fun, way more reliable and, if anything, better built (the 1200gsa had recall after recall, the last one before I sold it was to stop the diff fracturing and falling off the bike).Besides the intermittent turn signal issue (dangerous), my 790 is leaking from the valve cover gasket on both left and right sides. With only 3600 miles on, I'm pretty sure it the VCG has never been removed since assembly at the factory in Austria.I feel for the owners of the Chineses built bikes. My Indian built 390 Duke is a hoot to ride, but the gas cap still doesn't align correctly and that's been replaced under warranty. The kickstand nearly fell off after a week of ownership, and the computer and clock are pure gobbledegook. Made in India. Almost expected. But not from Made in Austria.
Engineering is one thing; build quality and after the sale service entirely another. No doubt, their bikes are unique and very fun to ride, but the older I get, the less tolerant I am of poor quality - both in manufacturing and especially in after the sale customer service - and I'm not talking about the dealer here. Reputation is valuable currency. It can take a long time to accumulate, but can be squandered very quickly.
