Yamaha FZ1 Problems by year

The weld that holds the different sections of the frame of the motorcycle has a crack. The weld from the manufacture is defective. The crack is in parallel and in the middle of the weld. It is clearly visible on both sides of the bike just below the gas tank. The crack can cause the bike to fall apart during riding putting the rider and nearby traffic in mortal danger.

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.

I noticed the frame is cracked on the weld on the right side!!! The bike has never been dropped. This is a manufacturing defect!!!

Due to manufacturer design the magnets on the stator fly wheel became compromised. The result is a failed charging system. Possible internal motor damage as well. I was on the freeway when I smelled the components burning up and my seat became very hot. *Tr

While turning left through a city intersection the engine died forcing me to push motorcycle through remainder of turn to avoid a collision with approaching traffic. Although the mileage/time on my particular vehicle is out of factory warranty, a small amount of research shows this to be a common issue with yamaha fz1, fz8, & 2004-2006 yamaha r1 (same engine configuration). Also the manufacturer has released a redesigned component to address this situation.

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.
