While riding 45 MPH in second gear the contact attempted to accelerate to merge into traffic and the vehicle shut off and was struck by another vehicle under normal road conditions. The contact had to let the rpms decrease to under 5,000 and turn the throttle in order to accelerate. The failure recurred after the vehicle was test driven at 45 MPH. The vehicle has not been inspected by the dealer. The current and failure mileages were 56.
Tl*the contact owns a 2007 yamaha yzfr1. While driving in second gear at 48 MPH or 5500 RPM, the vehicle would take approximately four seconds to accelerate when the throttled was turned. This failure has occurred on approximately 20 occasions. The dealer was able to duplicate the problem, but was unable to diagnose the failure. The manufacturer informed the contact that there were no failures with the vehicle. The current and failure mileage were 380.

I purchased my motorcycle brand new and noticed one day while trying to accelerate in second gear after slowing that the bike did not respond. The bike acted as if in slow motion and then all of a sudden the power returned to it. It will continue to do it to this day and I do not know why. I have since learned it is a widespread problem. I believe it is a very real safety issue due to the fact that it has happened once when I was trying to get out of the way of a vehicle that was moving into my lane. Luckily they noticed me at the last minute but I can't expect that to always be the case.
Tl*the contact owns a 2007 yamaha yzfr1. While attempting to accelerate from 47 to 55 MPH the vehicle hesitated for three to five seconds. The failure has been occurring since the vehicle was purchased fourteen days ago.

The current mileage was 636, and failure mileage was 50.*ak the consumer provided information on other complaints pertaining to the same problem. Updated 05/04/07
There is a throttle lag on my 2007 yamaha r1 for about 3 seconds at second gear 5500 rpms.
I was riding on the freeway on route 1. I tried to pass a car in traffic in 2nd gear at 5500 RPM no throttle response for approximately 4 seconds. This bike did not accelerate from 5500 rpms in 2nd gear properly. Having no throttle response in 2nd gear at 5500 could have cost me my life. Yamaha said there was nothing wrong with the bike. Please help before someone got hurt .
The 2007 yamaha r1 motorcycle with fly-by-wire throttle has a definite lag of throttle. This seems to happen a lot at 5,500 rpms while in 2nd gear. When it occurs there is at least a 6-8 second lag in the throttle. It feels like the engine shut off , then it very slowly comes back to life. I feel this problem every time I ride the motorcycle and can reproduce it at will. This almost caused me to get in an accident being rear-ended. I have contacted the local dealer, who said it wasn't an issue , and also yamaha who told me that this was the way it was supposed to be. To me this seems to be a safety issue because when it happens the motorcycle will not accelerate. I a wonder if there is a glitch with the throttle-by-wire system where there isn't any throttle... Can a problem occur where the throttle will go wide-open for a few seconds. This seems like a dangerous issue to me.
I am experiencing throttle lag on my 2007 yamaha yzf r-1 motorcycle. When I am in 2nd gear and at 48 MPH when I twist the throttle there is a delay in power delivery, and then all of a sudden it takes off. It only happens in that situation. It works fine in any other.
2007 yamaha yzf-r1 has an acceleration lag in second gear when trying to accelerate from 5,500 RPM. Acceleration from less RPM, or more the lag is not present, but it is always present in second gear at 5,500 RPM. When this lag occurs it is present for several seconds before the bike will accelerate. When it does start to accelerate, it is a slow soft acceleration regardless of throttle input. It seems to me that in this case you do not have full control over the motorcycle, which is very dangerous and life threatening to the rider and to those around (pedestrians, cars). At this time I have not noticed any other faults in the drive by wire throttle, but this problem is scary. What is to say that the throttle will stay open when you do not intend? This is an issue that needs to be addressed immediately. Motorcycle was purchase new on 3/3/07 and this issue was discovered on 3/4/07 with 62 miles on the bike at first occurrence. As of 4/4/07 bike has 669 miles and this issue is still present. It will hesitate on every attempt. Dealer is aware and will inspect on the bikes first service in one week.
When riding in second gear at approximately 5500 RPM, and hitting the throttle you get nothing, no acceleration for a good 2 seconds. Had heard about others having this problem but I hadn't experienced it until today. Nothing was done to correct the failure. As a matter of fact , upon further reading, yamaha has downright ignored this problem and their customer base by not fixing it outright on every bike afflicted by this problem.
2007 yamaha r1- the other day I was in rush hour traffic on my motorcycle. I was driving at approximately 45 MPH in second gear when the car next to me began to merge over on me. I tried to accelerate to avoid a collisions but my bike did not immediately respond to the throttle. Fortunately I was able to maneuver out of the was of the merging vehicle.. The lag in the throttle response seemed very strange to me so I decided to test the bike by recreating the scenario. My finding were, if I ride the motorcycle in 2nd gear at approximately 48 MPH (5500 RPM) and try to quickly accelerate (ie- to avoid a collision,,,etc), the bike will lag and accelerate slowly. This defect was consistent each time I tested the bike. All other gears and speeds, acceleration was perfect. Before contacting the dealership about my problem, I decided to do some research online. I did a google search for 2007 yamaha r1 lag, and to my surprise, I got countless results on the topic. Apparently the issue is found in all 2007 yamaha r1s in the u.s. Now, being an experienced rider, I can surly say that 40 to 50 MPH are very common speeds for a motorcyclist who travels city streets. And its a fact that acceleration along with proper braking and maneuver ability, are key components to riding a motorcycle and avoiding life threatening situation while in traffic. The yamaha website clearly states,,,the yzf-r1 uses the ycc-t fly-by-wire throttle system for flawless response under all conditions. Yamaha chip control throttle controls a 32-bit ecu fuel injection system for super-responsive, smooth, instantaneous power delivery. This is far from truth and yamaha needs to address this issue.
I was riding my motorcycle on the highway while I came up behind a car in the right lane. The speed limit is 65 MPH and the car was doing 50 MPH in 2nd gear. I decided to pass the car in the left lane. I signaled to get into the left lane checked my mirrors and started to move over and at the same time accelerate. For some reason it felt like the motorcycle turned off. There was no acceleration for about 2 seconds. I was lucky that there was no cars in the left lane. After about 2 seconds the bike accelerated as normal. I looked up the information online about this issue and I found out this problem is common for all the 2007 yamaha r1's in the USA. I have already duplicated this problem over 10 times in second gear at 5500 RPM's.
I have recently purchased the 2007 yamaha yzfr1 and have some concerns regarding the safety of this vehicle. First off I would like to report the issue of a flat spot in acceleration. When the vehicle is at approximately 5500 RPM and throttle is applied there is a delay in acceleration lasting between 3-5 seconds. This delay could cause injury or possible death due to accidents occurring when acceleration in this range is necessary. The second issue is with the rear set (foot pegs). Although this has not occurred on my vehicle, there have been cases of the set cracking and breaking. If this were to happen while the vehicle was in motion it can cause injury or possible death.
While driving in rush hour traffic I observed a car behind me was approaching fast. I rolled on the throttle to accelerate , and nothing happened for about three seconds. Then bike began to slowly accelerate and I was almost rear ended because of this defect. Well, I was almost rear ended because the driver behind me was not paying attention. But the bike's defect could have killed me. Yamaha continued to ignore this defect by saying that they have not heard of this before. This was a lie, and could be proven. Yamaha knew of this defect and chose to completely ignore it. Not enough deaths yet?
No power in 2nd gear at 5500 RPM could cause accident when rolling out of a 45 to 50 MPH curve nothing has been done yet!
My 2007 yamaha yzf r1 does not accelerate correctly if you are in 2nd gear and are running the engine near 5000 RPM. When you accelerate, there is a 3-4 second lag before the bike begins to respond. This is very dangerous if you need that quick motion to get out of a traffic/problem situation.
Brand new motorcycle: 2007 yamaha yzf-r1. In 2nd gear at 5500 RPM, the acceleration is literally gone no matter how much throttle you give it. It could be a serious problem and cause an accident if in a bad circumstance when this happens. It is recurring every time at that RPM. It is definitely a manufacturer's defect that must be fixed!!!
I have an 07 yamaha yzf-r1. The bike has throttle lag @ 5500 rpms in second gear, all the 07 us models have this safety issue that needs to be fixed.
On my 2007 yamaha r1 motorcycle there is a significant lag' with the throttle response during normal operation at highway speeds. When in 2nd gear and steady at approximately 5500 rpms if attempting to accelerate , ie. To avoid something or someone, the throttle does not instantly respond when applied. This is very dangerous in my opinion ,and the dealer says that yamaha is aware of the problem but does not have a solution.
2007 yamaha yzf-r1, significant power lose in second gear at 5500 rpms. While in second gear if I hold steady at 5500 miles and approximately 48 MPH for a few seconds then apply the throttle the motorcycle does not pick up speed as normal. At 5000 or 6000 rpms the motorcycle picks up speed as normal. I can duplicate this problem at will and have done so many times. This problem will also arise in corner exit and traffic merging. A lose of power with a car on ones tail is scary at best and deadly at worst.
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.
There is a lag in second gear which keeps the bike from accelerating. Sometimes it will return, which if unexspected, can cause injury. The lag is soo delayed it takes anywhere from 2-5 seconds before it responds to the rider input. This issue is duplicable @5500 in second gear, or simply 48-49mph. Dealers were saying it was not an issue. Replacement on several parts yield, no change to the above issue. Also, rt. Side foot braket broken in two
Throttle hesitation when accelerating.
I have a 2007 yamaha yzf-r1 motorcycle. I bought it last month and became aware of a throttle glitch with the bike. When the bike is running in second gear at 5500 RPM which is 48 MPH, the bike is extremely slow to response to changes in the thottle, particularly accelerating. There is about a 3-4 lag. I am conserned because motorcyclist are already at a disadvantage if they are facing an accident. One of the only things they have going for them is to be able to out manuver the situtation. If the yahama 2007 yzf-r1 does not respond for several seconds this takes away our only advantage will facing an accident.
Throttle lag in 2007 yamaha r1. If I ride at about 5500 rpms then apply the throttle, there is a lag of several seconds before the bike responds. Because I commute daily in rush hour traffic, I feel that this can put me in danger if I need to make a speed change in an emergency situation.
When trying to apply throttle at certain engine speeds there is no throttle response. This occurs frequently, and has almost caused incidents that put me and others in harms way.
