2007 Yamaha YZFR1

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 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 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.

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
