2007 YAMAHA YZF-R1 SUPER SPORT MOTORCYCLE. THERE IS A CONSTANT FAILURE MODE IN THE ENGINE MAPPING THAT CAUSES SLOW ENGINE ACCELERATION IN THE FOLLOWING CONDITIONS: 2ND GEAR, 5500 RPMS. THIS CONDITION CAN BECOME A SIGNIFICANT SAFETY ISSUE WHEN MANEUVERING IN HEAVY TRAFFIC, OR EXPECTING ENGINE POWER TO HELP STAND THE MOTORCYCLE UP AFTER A TIGHT TURN. AFTER CONTACTING YAMAHA, I WAS TOLD THAT THE ENGINEERS HAS EVALUATED THE CONDITION AS A CHARACTERISTIC OF THE MOTORCYCLE AND NOT A SAFETY ISSUE. YAMAHA HAS NO PLANS TO CORRECT THIS ISSUE.

I PURCHASED MY MOTORCYCLE BRAND NEW AND NOTICED ONE DAY WHILE TRYING TO ACCELERATE IN SECOND GEAR AFTER SLOWING THAT THE BIKE DID NOT RESPOND. THE BIKE ACTED AS IF IN SLOW MOTION AND THEN ALL OF A SUDDEN THE POWER RETURNED TO IT. IT WILL CONTINUE TO DO IT TO THIS DAY AND I DO NOT KNOW WHY. I HAVE SINCE LEARNED IT IS A WIDESPREAD PROBLEM. I BELIEVE IT IS A VERY REAL SAFETY ISSUE DUE TO THE FACT THAT IT HAS HAPPENED ONCE WHEN I WAS TRYING TO GET OUT OF THE WAY OF A VEHICLE THAT WAS MOVING INTO MY LANE. LUCKILY THEY NOTICED ME AT THE LAST MINUTE BUT I CAN'T EXPECT THAT TO ALWAYS BE THE CASE. *JB

I KNOW IN FACT I'M NOT THE FIRST TO MAKE A COMPLAINT REGARDING AN ISSUE THAT I HAVE ON MY 2007 YAMAHA YZF R1 MOTORCYCLE. THE FOLLOWING IS THE BEST DESCRIPTION I CAN GIVE FOR A THROTTLE LAG PROBLEM IN THE 2ND GEAR AT APPROXIMATELY 5000-5500 RPM. THE MOTORCYCLE WILL NOT RESPOND TO THE THROTTLE OPENING AND HESITATES FOR APPROX. 2 SECONDS BEFORE IT WILL ACCELERATE. I FOR ONE THINK THIS IS VERY DANGEROUS ESPECIALLY DURING INTERSTATE RIDING WHEN THE NEED TO ACCELERATE RAPIDLY EXISTS. AT THIS POINT YAMAHA HASN'T RESPONDED TO THE PROBLEM AND I AM A MEMBER OF R1 FORUM.COM AND THE MAJORITY OF OWNERS OF THE 2007 MODEL HAS EXPERIENCED. I AM HOPING THAT NHTSA CAN HELP WITH THIS PROBLEM THAT YAMAHA REFUSES TO CORRECT AND HOPEFULLY GET A RECALL ISSUED. ANY HELP WITH THIS MATTER WOULD TRULY BE APPRECIATED. *JB
