What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
In the summer of 2005, while riding mid-turn, my 2004 yamaha yzf-r1 lurched and cut-out causing me to low side my motorcycle. I received minor injuries and my motorcycle was wrecked and is branded salvage on the title.
(1) around 5,000 miles I noticed my bike started stalling out at 4,000 rpm or less. (2) engine would idle really low and stall out. Bike would usually not start back up right away. Last year in the fall I was in a turn and my bike stalled out and I loss control and crashed.
The yamaha lost power, and he crashed into the face of the landing hill. And broke his collarbone on impact. After I made several inquiries I was surprised to learn that this is a common problem with this make and model of motorcycle since it introduction in 2001.
I recently purchased yamaha's new 125 vino scooter and after only 400 miles at rated speed of 50 mph (faster than most scooters), with normal driving, I was thrown and hit the pavement making dog meat of my body. I suspect the small front tire design at high speeds is a death trap. Can supply more details.
Then on highway lights and gauges started going on the interstate bike stalled lalmost locking up bike in curve while riding on wet road. Several tractor trailers were behind me and nearly almost killed me from the sudden change of speed due to bike killing power. Managed to get to side of interstate.
Engine suddenly stops without any kind of warning ,battery died ,at the shop I charge the battery ,test battery was good ,verified charging system at the moment not charge ,removed generetar to verified stator and found destroyed rotor assy's and plastic and magnets in the oil strainer.
Low speed, low rpm power loss. Total engine power loss (engine dies). Suspected tps failure. Took motorcycle to dealer ship for repair. Problem still exists. Took a second time to dealer, did not replace tps, said it checked out ok. I understand there is a 3rd generation tps that can be used.
Dt*: the contact stated the kickstand on the vehicle was too short. The weight of the vehicle bent the kickstand and caused the vehicle to fall damaging the vehicle. The sales/ service dealer was notified, but not the manufacturer.
