Wow Jeff thats an ugly batter. Glad you kept it on the rubber too.Glad to see you made it out in one piece. The same thing happened to me several months ago. Riding home at night on the freeway and big chunck of steel says hello to me. Was able to ride away as well but this stuff is a bummer.

I ordered new wheels, bearings, axles etc. from Pro Caliber but at that time they were backordered 3 months and were supposed to arrive on December 24. Well they came almost 2 months early and I have been riding ever since.
Got the old wheels repaired for $170 each. Many people to choose from to do the work.

Exactly what I was thinking. On other cast Yamaha wheels I've straightened I had to really wail on them with a dead blow hammer from over my head, striking them 30+ times to get them straight. I've only seen wheels flat sided after striking a road hazard until these FZ09 wheels. Yamaha may have trimmed the wheels of enough material to acheive light weight that their strengh was reduced. It appears these same wheels are on the 2015 adventure models. Those forum members considering taking their bikes off road should take wheel strength, or lack of it, into consideration.The rims I took off I was able to pound the bead back enough with a Rubber Mallet enough to hold air. I would not ride with them I just did it as a test until they were repaired. So this is my first street bike and my opinion may be "rookie" at best but they seem really thin and soft. My experience is with dirtbikes and if I were to compare both wheels strength wise here is a good example. If the FZ wheels were on the DB and I was riding a high speed wash and came upon a small gallon jug size rock they would have received the same damage. If I had it the roles reversed and DB wheels on the FZ I feel it would have been minimal damage. And NO you cant pound back DB wheels with a mallet.
So YES they are freakin weak for a 415lb machine.
Hit a curb the wrong way even at low speed and these wheels are going to smile the opposite direction.
I don't see Yamaha touting their new sacrificial, impact absorbing wheels as a new industry first safety innovation or that the ownership cost of this safety innovation is the price of a new set (both) wheel after hitting a road hazard.And if they made them heavier everyone would be complaining about heavy wheels. No matter what Yamaha does someone will find something to complain about.
How heavy would a wheel have to be to not incur any damage from an impact in which the rider almost crashes??? Did the fact that the wheels absorbed some of the energy of the impact help prevent the rider from crashing?
Take a look at vehicle design and you will see many instances in which parts were designed to flex or crush and absorb impact that otherwise would be transferred directly to the driver/rider.
I am confident Yamaha will continue to design their products by folks with real degrees.
