Filed May 11, 2016 · Electrical, Fuel system · 16,000 miles · GA

I almost dropped the bike with my son on the bike with me in a intersection and was almost struck by another vehicle due to the loaf in throttle in first gear. The bike stumbles and misfires from idle up till around 2000 rpms. This has happened several times. I have notified yamaha directly with no help. They started changing out the computers in the bikes then they stopped. I just bought the bike with the extended warranty. This is a very dangerous problem especially having my child on the bike when this took place. We were lucky that we barely were missed by a car due to the bike stumbling and shift off in the intersection as I was making a left hand turn. It took everything in me to prevent my son from being struck by the oncoming vehicle. This is a major problem with the 07 and 08 models. There are few complaints probably due to the other owners died on this bike before being able to file a complaint. We were on a city street at a intersection. As I went in motion the bike stalled in the middle of the intersection and almost hit us both killed. They need to recall these bike and permanently fix them.

2007 and 2008 yamaha r1 motorcycles have faulty ecu which causes bike to stall when coasting or stopping and lag when accelerating at certain RPM ranges. This creates a dangerous situation for both the rider and other motor vehicles in the vicinity. Yamaha motor corporation has been made aware of this problem and initially exchanged faulty ecu's at no charge but quickly stopped doing this. I have been in contact with the manufacture and with the local dealerships, both when I was under warranty and after it had expired, and have not been able to resolve this issue.

Purchased 2007 yamaha yzfr1 last september. The bike exhibited a lag in the throttle around 5,000 RPM, and the engine will also stall at random, usually at the worst time. This bike has stalled at least 20 times at intersections, and stalled another 6 times just yesterday! The throttle lag issue has been fixed by a dealer. The stall has not been fixed. The stall problem scares me. It may lead to my death!!! Yamaha needs to fix this now!

The 2007 yamaha yzfr1 had intermittent and significant loss of power and stalled while riding. This was a well known problem that yamaha was avoiding to recall. It was exceedingly dangerous.

The 2007 yamaha yzf-r1 has significant lag or aflat-spot" if you will at approximately 48 MPH in second gear. Any attempt to roll on the throttle at that point will result in the bike nearly stalling and or cutting out before slowly accelerating. This creates a dangerous situation for any owners of the motorcycle. If you ever had to accelerate out of a problem at that speed, you might as well just brace for impact. Also, 45 MPH is a very common speed limit in our local area, and it was not a pleasant feeling when you roll on the throttle and nothing happens. Keep in mind, my 10 failures is just the beginning. It is 10 and counting.

Run the bike in second gear with the rpms at 5500 which is around 48 MPH. Hold your bike steady at this RPM for a moment and then open the throttle pretty full. You will notice that the bike takes between 3-4 seconds before it will respond also the bike is stalling out in a low gear also starting issues please note I know what I am talking about (reason) I had a 2006 yzf r1 that was stolen so I know what to expect from the motorcycle

2007 yamaha yzf-r1, stalling issue. Was stopped at a red light with traffic in front and behind me. The light turned green, traffic started to move. I started to move forward. Traffic slowed down so I closed the throttle and pulled in the clutch , and the motorcycle died. This happened three times under the exact same circumstances.

I have purchased a 2007 yamaha yzf r1 and would like to make a complaint about the throttle lag in 2nd gear at 5500 RPM. I was entering the freeway (I-5) and was about to merge into traffic when I was attempting to accelerate to merge in traffic the throttle basically stalled at speed and slowly began to pick up speed. It has also been an issue while changing lanes on the freeway and turning corners on off ramps. The engine does not correspond with the throttle while attempting to accelerate and has caused me to run off the road while in a corners twice and nearly get hit by other vehicles on the freeway. When the engine finally spools up and the lag is gone the bike takes off suddenly and you have to hold on. I have called yamaha and taken my bike to two different dealerships. The yamaha customer service rep told me to replace the counter shaft sprocket and this would be a fix for the problem. I did this and the problem is not gone and now I have a speedometer that is incorrect. Yamahas response was sorry for telling you so fast to replace a part when we didnt know the fix. There is nothing that we can do for you now at this time. I hope that there is something taked care of soon before one of the 07 r1 riders is injured or even worse killed.

The 2007 yamaha r1, stalls for no reason at all and in 2nd gear at 5500rpm there is a huge lag and it also occurrs at 50 MPH, and with speedo error that is usually associated w/motorcycles, that means that were roughly going about 45 MPH, which is the expressway speeds in california and if we need to accelerate for any type of emergency situation, it takes the bike 3-4 seconds before it responds and starts accelerating. This is a huge safety issue. And I own 2 of these motorcycles and will be doing 2 separate complaints as well.
