2007 Yamaha YZFR1

THE 2007 YAMAHA YZF-R1 HAS SIGNIFICANT LAG OR AFLAT-SPOT" IF YOU WILL AT APPROXIMATELY 48 MPH IN SECOND GEAR. ANY ATTEMPT TO ROLL ON THE THROTTLE AT THAT POINT WILL RESULT IN THE BIKE NEARLY STALLING AND OR CUTTING OUT BEFORE SLOWLY ACCELERATING. THIS CREATES A DANGEROUS SITUATION FOR ANY OWNERS OF THE MOTORCYCLE. IF YOU EVER HAD TO ACCELERATE OUT OF A PROBLEM AT THAT SPEED, YOU MIGHT AS WELL JUST BRACE FOR IMPACT. ALSO, 45 MPH IS A VERY COMMON SPEED LIMIT IN OUR LOCAL AREA, AND IT WAS NOT A PLEASANT FEELING WHEN YOU ROLL ON THE THROTTLE AND NOTHING HAPPENS. KEEP IN MIND, MY 10 FAILURES IS JUST THE BEGINNING. IT IS 10 AND COUNTING. *AK

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

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. *TR

I RECENTLY PURCHASED THE 2007 R-1 MOTORCYCLE AND HAVE BEEN HAVING CONTINUOUS PROBLEMS WITH THE THROTTLE LAG. 2ND GEAR AT 5500 MPH THE MOTORCYCLE HAD NO POWER. I FOUND THIS TO BE VERY DANGEROUS WHEN PASSING VEHICLES AND ACCELERATING THROUGH TURNS. I FELT THAT YAMAHA WAS NOT DOING THEIR PART TO FIX THE PROBLEM. $12,000 LATER AND UNHAPPY. PLEASE HELP. *AK

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.*AK

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! *AK
