(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

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

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

TL*- THE CONTACT STATED THAT WHILE DRIVING THE 2007 YAMAHA YZFR1 AT 4 MPH, AND ATTEMPTING TO ACCELERATE FASTER THE MOTORCYCLE HESITATED FOR A COUPLE OF SECONDS THEN EVENTUALLY ACCELERATED SLOWLY. THE MOTORCYCLE HAD AN ACCELERATION PROBLEM EACH TIME ITWAS DRIVEN. THE MOTORCYCLE HAD BEEN TAKEN TO A DEALER, WHO CONFIRMS THE PROBLEM EXISTED, AND STATED THAT THERE WAS NO REMEDY FOR THE FAILURE. THE CURRENT MILEAGE WAS 230 , AND THE FAILURE MILEAGE WAS 0.*AK THE CONSUMER STATED THE PROBLM ONLY HAPPENED IN SECOND GEAR. UPDATED 04/05/07. *JB
