2007 Yamaha Yzfr1 complaints

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

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!!! *JB

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. *JB

THE MOTORCYCLE HAS STALLED ON SEVERAL OCCASIONS, WHEN SLOWING DOWN WITH THE CLUTCH ENGAGED. *JB

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. *JB

2007 YAMAHA R1, RIDING DOWN THE LOCAL HIGHWAY WITH SOME FRIENDS AND THE RIGHT REAR SET CRACKED AND AS IT BROKE FREE FROM THE BIKE, MY FOOT HIT THE GROUND DOING ABOUT 65 MPH , CAUSING ME TO SHATTER 1 TOE WITH AN OPEN FRACTURE, BREAK ANOTHER IN HALF AND FRACTURE THE TIP OF THAT TOE. THE REARSET WAS CRACKED AT THE UPPER MOST LEG" RIGHT WHERE IT CONNECTS TO THE MOTORCYCLES FRAME. ALSO AS A RESULT FROM THIS BROKEN REARSET, I HAVE SCRATCHES ON MY SWINGARM AND A PIECE OF PLASTIC IS BROKEN ON THE EXHAUST COVER FROM WHERE THE REARSET DROPPED AND SINCE EVERYTHING IS CONNECTED IT JUST BROKE THE PLASTIC AND LEFT SCRATCHES IN THE SWINGARM. LOCAL YAMAHA DEALERSHIP HAS AGREED TO REPLACE THE RIGHT REARSET UNDER WARRENTY AND HAS CONTACTED YAMAHA ABOUT THE ISSUE. THE DEALERSHIP ALSO HAS THE OLD REARSET THAT IS BROKEN, AND I ALSO HAVE MULTIPLE PICTURES OF THE BROKEN REARSET, SCRATCHES IN MY SWINGARM, BROKEN PLASTIC COVER, X-RAYS, AND OTHER PHOTOS OF THE ACCIDENT. NO POLICE REPORT WAS FILED HOWEVER THE POLICE, AMBULANCE, FIRE DEPT WAS ON SCENE AND THE POLICE OFFICER HAS LEFT HIS NUMBER AND BADGE NUMBER INCASE A REPORT NEEDS TO BE FILED.*AK

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. *AK

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*AK

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.*AK

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.*AK

THROTTLE HESITATION WHEN ACCELERATING.*AK

I HAVE A 2007 YAMAHA R1, AND WHILE RIDING IN 2ND GEAR AT 55MPH I HAD A LOSS OF POWER WHEN I WAS ATTEMPTING TO MERGE ON THE HIGHWAY. YAMAHA IS AWARE OF THIS PROBLEM AND REFUSES TO DEAL WITH IT. *AK

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.

I PURCHASED A 2007 YAMAHA YZF-R1 ABOUT 3 WEEKS AGO. WHEN RIDING THIS MOTORCYCLE IN 2ND GEAR AT 5500 RPM (APPROXIMATELY 45 MPH), THERE IS ABSOLUTELY NO THROTTLE RESPONSE FOR 2 TO 3 SECONDS - ALMOST AS IF IT IS RUNNING OUT OF GAS. MY DEALER CONTACTED YAMAHA AND WHILE DESCRIBING THE DEFECT WAS INTERRUPTED BY THE YAMAHA REPRESENTATIVE... "LET ME GUESS, 2ND GEAR AT 5500 RPM? THE ANSWER IS TMDT... THAT MODEL DOES THAT. THAT'S THE WAY THE COMPUTER IS PROGRAMMED AND THERE IS NO FIX. THE BIKE SHOULD BE RIDDEN THE WAY IT WAS MEANT TO BE RIDDEN TO AVOID THIS." IN OTHER WORDS, THEY ARE SUGGESTING THE BIKE SHOULD BE RIDDEN LIKE A RACE BIKE. THIS WOULD BE VERY DANGEROUS ON PUBLIC ROADS WITH OTHER TRAFFIC.

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.

I JUST BOUT A NE 2007 YAMAHA R1 A FEW WEEKS AGO. THIS WAS ONE OF THE WORST PURCHASES I MADE DO TO THE BAD LAG THAT THIS BIKE HAS.. FROM WHAT I MINE IS NOT THE ONLY ONE DOING IT. JUST NOT SURE WHAT TO DO. I ALREDY TOLD THE DEALERSHIP ABOUT IT BUT THEY SAID THAT THEY WOULD CALL THE MANUFACTURE.R. *AK

THE 2007 YAMAHA R1, STALLS FOR NO REASON AT ALL AND IN 2ND GEAR AT 5500 RPMS THERE IS A HUGE LAG AND IT ALSO OCCURS AT 50 MPH, AND WITH SPEED 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.*AK

WHY DOES MY 2007 R1 NOT RESPOND IN SECOND GEAR AT CERTAIN RPMS. *AK

WHEN VEHICLE IS IN SECOND GEAR AT 5500 RPMS IT HAS A TEMPORARY LOSS OF POWER. IT IS A DANGER WHEN TRYING TO MERGE INTO TRAFFIC. ONLY NORTH AMERICAN BIKE HAVE THIS PROBLEM AS FAR AS I KNOW.*AK

WHILE RIDING IN NORMAL TRAFFIC CONDITIONS IN SECOND GEAR AT 5500 RPM S AT 48 MPH FOR A DURATION OF THREE OR MORE SECONDS AS IF CRUISING AT SPEED, APPLICATION OF THE THROTTLE PROVIDED LAGGING RESULTS. THROTTLE WAS APPLIED, AND THE MOTORCYCLE TOOK A UP TO TWO SECONDS TO REACT. THIS CONDITION IS REPEATABLE, AND THERE IS INSTANT THROTTLE RESPONSE AT 5000 RPMS AND 6000 RPMS IN THE SAME CONFIGURATION. THIS COULD BE AN ISSUE IF A RIDER IS FORCED TO WATCH GAUGES AS OPPOSED TO TRAFFIC TO STAY OUT OF AN RPM RANGE AS OPPOSED TO A POSTED SPEED. FURTHER THIS COULD CAUSE AN ISSUE WHERE INSTANT THROTTLE APPLICATION COULD BE THE ONLY ESCAPE TO AN EMERGENCY SITUATION (I.E. CROSS TRAFFIC DISOBEYING A TRAFFIC LIGHT OR A VEHICLE APPROACHING FROM BEHIND TOO QUICKLY). THIS ISSUE HAS BEEN REPORTED TO THE DEALER WHERE THE VEHICLE WAS PURCHASED FROM AS WELL AS YAMAHA CUSTOMER SERVICE. OTHER RIDERS HAVE REPORTED THE SAME ISSUE (REPEATABLE ON ALL BIKES WITH A US ENGINE CONTROL UNIT TO DATE), AND CURRENTLY, THE MANUFACTURER APPARENTLY DENIES THAT IT IS AN ISSUE.*AK

LOSS OF POWER WHEN TRYING TO MERGE INTO TRAFFIC IN SECOND GEAR AT 5500 RPM'S.*AK

THE MOTORCYCLE WILL LAG AND NOT ACCELERATE WHEN THE RPM IS HELD AT 5500 RPM IN SECOND GEAR. THIS IS NOT A CHARACTERISTIC OF THE MOTORCYCLE. YAMAHA NEEDS TO BE AWARE OF THIS ISSUE AND CORRECT IT. THIS A DANGEROUS ISSUE THAT COULD RESULT IN SERIOUS INJURY OR DEATH TO THE RIDER.*AK

SIGNIFICANT THROTTLE LAG AT 5500 RPM. THE LAG IS ABOUT 3 TO 4 SECONDS THEN THE BIKE STARTS TO ACCELERATE. IN MANY SITUATIONS, THIS LAG AND SUBSEQUENT POWER SURGE CAN BE AN SAFETY ISSUE. POWER DELIVERY CAN COME WHEN THE RIDER LEAST EXPECTED IT. THIS COULD CAUSE THE RIDER TO PANIC OR CAUSE OTHER MOTOR VEHICLES TO MAKE EVASIVE MANEUVERS.*AK

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.*AK

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.

IF I TWIST THE THROTTLE AT AROUND 5500 RPM (MORE OR LESS) THERE SEEMS TO BE A LACK OF POWER OR THROTTLE LAG. IT TAKES SEVERAL SECONDS BEFORE THE BIKE ACCELERATES LIKE IT WAS DESIGNED TO. THIS ONLY HAPPENS IN 2ND GEAR @ 5500 RPM.

2007 YAMAHA R1 MOTORCYCLE HAS A PROBLEM! THE ENGINE CUTS OUT AT AROUND 5500 RPM. IF YOUR AT THIS RPM AND OPEN THE THROTTLE IT WILL NOT RESPOND AT ALL FOR A FEW SECONDS, THEN IT WILL TAKE OFF. I FOUND THIS TO BE VERY DANGEROUS. IT ALMOST COUSED AN ACCIDENT.*AK

THE ELETRONIC THROTTLE (FLY BY WIRE) SYSTEM HAS A DANGEROUS LAG @5500 RPM IN 2ND GEAR. IF YOU DRIVE IN 2ND GEAR AT 5500 RPM FOR A COUPLE OF SECONDS AND THEN TRY TO ACCELERATE, THE MOTOR DOESN'T RESPOND AS IT SHOULD. IT VERY SLOWLY ACCELERATES. THIS IS REPRODUCIBLE EVERY TIME.

TL* - THE CONTACT OWNS A 2007 YAMAHA MOTORCYCLE YZF-R1. WHEN THE MOTORCYCLE IS IN 2ND GEAR AND AT 5500 RPMS, THE MOTORCYCLE HESITATES FOR APPROXIMATELY 3-4 SECONDS WHEN HE TRIED TO ACCELERATE.

THE CONTACT SPOKE WITH THE MANUFACTURER, AND THEY STATED THE SAMETHING. THE VEHICLE CURRENTLY HAS 3500 MILES. *AK

AFTER STEADYING THE THROTTLE IN SECOND GEAR, AT 5500 RPM, 48 MPH, AND THEN APPLYING THROTTLE, THE MOTORCYCLE, DOES NOT ACCELERATE PROPERLY, AND LAGS SEVERELY. THE LAG IS SO SEVERE THAT A RIDER RUNS THE RISK OF BEING HIT FROM THE REAR, ESPECIALLY IN A TRAFFIC SITUATION, WHEN MERGING FOR EXAMPLE. THROUGH GENERALIZED RESEARCH, I HAVE DETERMINED THAT THE PROBLEM CAN BE RECREATED ON ANY US VERSION 2007 YAMAHA R1 MOTORCYCLE. THE PROBLEM CANNOT BE RECREATED ON A DYNOMETER. CHANGING THE GEARING, EXHAUST, PCIII, AND OR IGNITION MODULE DOES NOT CORRECT THIS PROBLEM. *JB

WAS RIDING MY 2007 YAMAHA R1 AND THE FOOT PEG SNAPPED OFF OF THE MOTORCYCLE. THIS HAS HAPPENED TO SEVERAL OTHER RIDES AND 1 EVENR BROKE HIS FOOT BECAUSE OF IT.

TL* THE CONTACT OWNS A 2007 YAMAHA YZFR1 MOTORCYCLE. WHILE TRAVELING AT 55 MPH IN SECOND GEAR THE VEHICLE DID NOT ACCELERATE FOR 2 TO 3 SECONDS WHEN THE DRIVER INCREASED THE SPEED.

(1) THROTTLE LAG ON 2007 YAMAHA R1, TRY TO ACCELERATE IN 2ND GEAR AT 5500 RPM'S AND THE BIKE DOESN'T MOVE, THEN ALL OF THE SUDDEN A VIOLENT JERK AND THE BIKE IS NOW VIOLENTLY ACCELERATION. (2) I WAS IN TRAFFIC TRYING TO PASS A VEHICLE AND ALMOST GOT RUN OVER DUE TO THE LAG. THERE IS NO FIXED REPORT, BUT THE EUROPEAN BIKES DON'T HAVE THIS SO A NEW ECU WOULD FIX IT. OR A REFLASH OF THE ECU. (3) THE REARSET (AKA FOOTPEG BRACKETS) ARE BREAKING OFF WHEN WEIGHT IS APPLIED. STANDING UP ON THE BIKE OR JUST PUTTING PRESSURE ON THEM WILL CAUSE THEM TO SNAP. (4) FRIEND WHO HAS THE SAME BIKE BROKE HIS FOOT WHEN THE RESET BROKE. (5) HAD TO BUY AFTERMARKET REAR SETS TO AVOID THIS PROBLEM. SPENT $ 500, ON A PRODUCT I SHOULD NOT HAVE TO BUY..YAMAHA NEEDS TO REIMBURSE ME OR SEND ME NEW ONES. *JB

THE 2007 YAMAHA YZF-R1 HAS TWO ISSUES THAT HAVE COME TO MY ATTENTION. FIRST, THERE IS A LAG IN THE 2ND GEAR MAPPING THAT SIGNIFICANTLY DECREASES HORSEPOWER AT 5500 RPM WHEN THE THROTTLE IS OPENED. SECOND, THERE HAVE BEEN NUMEROUS INSTANCES OF THE REAR SETS (THE HARDWARE WHERE YOUR FEET REST) CRACKING. BOTH IF THESE ITEMS ARE SAFETY ISSUES THAT COULD LEAD TO FATAL ACCIDENTS. *JB
