2007 YAMAHA YZFR1 Complaints

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. *AK

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. *AK

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. *JB

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. *JB

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. *JB

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. *JB

2007 YAMAHA YZF R1. WHILE IN SECOND GEAR AND AT 5500 RPMS THE MOTORCYCLE DOES NOT PERFORM AS EXPECTED WHEN THROTTLE IS APPLIED. THE MOTORCYCLE HAS A LAG IN ACCELERATION THAT UPSETS OR CAUSES AN UNSAFE SHIFT IN UNPREDICTABLE WEIGHT WHILE IN A TURN. THIS IS OF GRAVE CONCERN FOR MY SAFETY AS THIS UNPREDICTABLE CHARACTERISTIC HAS PLACE ME IN CLOSE CALL ACCIDENTS SEVERAL TIMES. *JB

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. *JB

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? *AK

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! *JB
