2007 Yamaha YZFR1 Problems

What owners report

Owners of the 2007 YZF-R1 complain overwhelmingly about a dead spot in throttle response: holding a steady throttle in second gear at roughly 5,500 rpm (about 48-50 mph) and then opening it produces a delay of several seconds before the bike accelerates. Most reports come from nearly new bikes, and a second, smaller cluster of complaints describes stalling at low speed or when coming to a stop. Complaints also mention a rear footpeg bracket and, at higher mileage, valve noise.

   Vehicle speed control

   Throttle lag in second gear around 5,500 rpm

   • 80 complaints (89%)
   • median 81 mi at 0.5 yrs old (60 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2007–2011

   Owners describe rolling on the throttle in second gear at a steady 5,500 rpm, roughly 45-50 mph, and getting no response for two to five seconds before the bike finally accelerates, sometimes with a sudden surge. Many say the condition repeats reliably in that one gear and rpm window and is absent just below or above it. According to complaints, dealers and the manufacturer often called it normal for the model, and some owners were told there was no fix; a few report a throttle control part or computer was replaced without solving it. Typically reported on nearly new bikes, mostly under 1,000 miles and often under 100 miles, at a steady 45-55 mph in second gear.

   What to check: Ride the bike at a steady 5,500 rpm in second gear, about 48 mph, hold it briefly, then open the throttle and see whether the response is immediate. Ask the seller whether any throttle or ECU work was done and whether it changed the behavior.

   “2007 Yamaha yzf r-1: a distinctive and dangerous throttle lag that occurs in 2nd gear at 5500 RPM that lasts for 3~5 seconds. I have had a close call under heavy traffic conditions. This is a serious issue that could lead to injury or deaths. Yamaha customer support was called and I was told that model does that and that they had no fix for it.”

   “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. …”

   Stalling at low speed and when coming to a stop

   • 16 complaints (18%)
   • median 21 mi at 0.5 yrs old (16 state mileage)
   • filed 2007–2016

   Some owners report the engine dying when they close the throttle and pull in the clutch, such as while slowing in traffic or rolling away from a light, and a few describe it cutting out repeatedly on a single ride. Others mention hard starting or a rough, stumbling idle below about 2,000 rpm. Complaints describe dealers replacing computers in some cases and later stopping, and a few owners say the stall was never resolved. Reported from very low mileage up to around 16,000 miles, mostly in stop-and-go and low-speed traffic situations.

   1 related service bulletin

   What to check: Ride the bike through slow traffic and to a stop, and see whether it holds idle when the clutch is pulled in. A service bulletin for related Yamaha models lists insufficient valve clearance as a cause of hard cold starting and poor idling, so ask whether valve clearance has been checked.

   “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.”

   NHTSA complaint #10186130, filed 2007-03, 1,300 miles

   “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”

   Body and structure

   Rear footpeg bracket breaking

   Mentioned in 5 of 60 sampled complaints

   Owners describe the bracket that carries the rear set and footpeg cracking or breaking at its mounting bolts, in one case when pressure was put on the peg while parking and in another after the bike was tipped over while stopped. The result reported is the bike going down when the bracket gave way. Complaints mention the part breaking with relatively little force rather than in a crash. Reported on bikes under about 100 miles in the sampled accounts, typically while stationary or pushing the bike.

   What to check: Inspect both rear set brackets closely around the mounting bolts for cracks or previous repair, and check whether either side has been replaced.

   “2007 Yamaha r1, throttle lagged at around 5500 rpms. No response for a few seconds. Can cause serious problems when need to speed up or take off before being ran over a SUV or in an intersection or overtaking another vehicle. Foot peg bracket broken. Was parking the bike when I put some pressure on the foot peg, it broke and myself and the bike went down. No injuries, just damages which I want to be reimbursed by Yamaha.... But it could be fatal in case of riding in traffic. …”

   NHTSA complaint #10187259, filed 2007-04, 82 miles

   “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). …”

Buying note. Most of the complaints for this model year center on throttle response in second gear at about 5,500 rpm and on occasional stalling at low speed, so a test ride covering both is worth more than a visual inspection. Check the footpeg brackets for cracks, and ask what service history exists for valve clearance and any throttle or computer work.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
