What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The frame has cracked at the frame weld point on the right side. This is the manufacturers weld from Yamaha. This is a known issue that has affected hundreds of thousands of 06-07 Yamaha FZ1 motorcycles. Yamaha knows of their welding error and chooses to do nothing about it.
It is common knowledge that the rotor assembly on similar year fz1, and r1 is so faulty, that yamaha redesigned the part and began selling it. It is irresponsible of them to not issue a recall on such a widespread failure costing countless owners hundreds if not thousands of dollars.
The machine is in mint condition with only 15,000 miles. On february 25th 2016 I noticed a large crack in the frame weld on the right side. It starts at the bottom and climbs the weld over 2 inches, cleanly through to the other side.
The contact stated that while driving 80 mph, the check engine warning light illuminated. In addition, battery failed. The contact noticed that the that pieces of the alternator had fractured because of they had demagnetize and fallen inside of the crank case. The vehicle was taken to the dealer.
The bike's electrical system completely failed. Bump start was impossible. A subsequent investigation performed by santa clara cycle in sunnyvale, ca determined the cause was a stator failure.
On the right side of the motorcycle, there is a weld that connects the upper part of the frame to the lower part of the frame. The weld is located just above the clutch cover. The weld has developed a center line crack.
