1. I was cruising in 2nd gear at 5500 rpms, I gave it gas but the bike didn't do anything, I started to let off the gas and all of a sudden there was a sudden burst of power, causing the rear end of the bike to kick out side ways and throwing me off the bike, flipping and tumbling. 2.the motorcycle failed to operate as it should have, the consequence was the motorcycle being destroyed and me being severely injured. 3. Nothing was done, yamaha denied my claim telling me that it was impossible for something like this to happen.

Payed $13,000 for a motorcycle that does not respond appropriately...2nd gear at 5500 RPM. Motorcycle will not accelerate until a good time after I've accelerated. Continues to happen and will not be eliminated until ecu is corrected by yamaha! Could cost someone their life or limb if injured.

2007 yamaha yzf-r1. While riding in second gear at 5500 rpms and when full throttle was used there was a lag of around 4 seconds. When dropping down to 5000 rpms or 6000 rpms, and using full throttle response was instantaneous.

When riding about 5500 rpms in second gear the throttle system became completely unresponsive. The engine will not gain rpms no matter how far the throttle was turned. One must let the throttle return to the starting position and then slowly turn it back to accelerate. This was a startling event, even when it is known to have occurred because in the course of riding there were so many other factors to be concerned with, such as noting the position of other traffic, steering, etc. This was a safety issue, and was most definitely a defect in the design/manufacturing of the vehicle.

In second gear going about 50 MPH when opening the throttle the motorcycle stayed at 50 MPH for approximately 3-4 sec before slightly accelerating at that point. The other day it almost caused me to get into an accident because I could barely get out of the way of a vehicle. I have since learned this happened with all 2007 yamaha yzf vehicles. When I contacted yamaha they said they were aware of it, but have no plans on fixing it yet or if they ever do!

On my yamaha yzf r1 there is a dangerous lack of respond time when the throttle is opened. When the speed limit is at least 50 MPH, and the motorcycle is running in second gear with the rpms at 5500 which is around 48 MPH, then hold the motorcycle steady at this RPM for a moment and then opening the throttle pretty full the motorcycle will takes between 3-4 seconds before it will respond.

Just purchased 2007 yamaha r1 motorcycle which now has 200 miles on it. The motorcycle will not accelerate when rpms are held at 5500 in second gear. Noticed the problem when trying to accelerate past a car before an intersection. The motorcycle would not accelerate , which LED to a potentially dangerous, possibly fatal scenario.

My 2007 yamaha r1 1. The bike cuts off almost every time I come to a stop. It does not matter whether the bike is in neutral or in gear with the clutch pulled in. It died approximately. 15-20 times on my ride. 2. If I blip/rev the bike in neutral or while in gear with the clutch pulled in, the bike shuts of as well. 3. I was merging on the freeway in second gear and when I went to speed up, the bike hesitated for about 3-4 seconds and then very slowly picked up. I was almost hit by the car behind me. I realized that if I'm at 5500 RPM's in second gear for a few seconds and then open the throttle, it causes this lag every single time. This is definitely not safe! I was almost rear ended by a car. 4. The bike also reached 250 degrees several times under cruising conditions. I can't even trust this bike to stay running either 'cause it seems it dies every time I come to a stop. 5. The bike also sometimes takes quite a few tries to start it. I have to hold down the starter for about 3-5 seconds sometimes.

Tl* the contact owns a 2007 yamaha yzfr1. While in second gear at 5500 rpms and when opening the throttle the motorcycle did not move. The accelerator gave no response for about four seconds. The manufacturer stated that since there was no recall there was nothing they could do to assist him. The current and failure mileage were 20.
