Come on guys. Let's not get too wound around an axle with all these "they lied to me" comments. Be a bit realistic. This is the first import of this bike to the U.S. There have always been risks of slipping dates. What mass produced item doesn't? Yamaha released a statement about projected delivery dates that they believed to be true at the time they stated it. In the end, like all projected dates, it is a target that can and will be moved based on various production and distribution schedules. It would only take one $4 part not being delivered by a vendor to delay an entire run for weeks. Now, how many parts on are this bike? Also the U.S. import and emission testing and certifications were probably an ongoing event at the time the projected delivery dates were released. Hasn't anyone worked on a project at any of your jobs that ran longer than scheduled? And those were likely much simpler than assembling a motorcycle and shipping it around the world.
I share everyone's disappointment, but to expect delivery date of a new-to-the-U.S. bike to be written in stone is unrealistic and you are setting yourself up for disappointment if you count on such things to be fixed. This is a fluid date and should be taken as an "estimate given to the best of our knowledge at this time" every time such a date is released. In the end, it will get here when it gets here and in the big pictures, unless you trade a bike every year, you'll long forget the extra month or two you had to wait. As others have mentioned, there are options. Get off the list (someone else will surely take your slot) and get a different bike, or buy a 'tweener bike, or do both (get off the order, buy a tweener bike, then buy a Super Tenere next year or the year after). Plenty of options.
