NHTSA Complaint #10161719 — 2004 YAMAHA YZF-R1

2004 YAMAHA R1 WILL OCCASIONALLY SURGE ERRATICALLY WHILE RIDING AND VERY OFTEN STALL, USUALLY DURING LOW TO NO THROTTLE CONDITIONS. THIS IS SOMETHING THAT STARTED TO MANIFEST ITSELF WHEN I BOUGHT THE BIKE WITH 1,000 MILES AND HAS PROGRESSIVELY GOTTEN WORSE AND I AM NOW AT 2,500 MILES. THIS IS A DANGEROUS CONDITION IN THAT THE STALLING WILL OFTEN TAKE PLACE WHILE APPROACHING A TRAFFIC LIGHT, STOP SIGN, OR CORNERING DURING SLOWDOWN. VEHICLES FROM BEHIND DO NOT REALIZE THE BIKE HAS STALLED, AND SOMETIMES WANT TO KEEP ON GOING INTO THE BACK OF YOU. ITS A NUISANCE AND DANGER NOT ONLY TO THE RIDER OF THE MOTORCYCLE, BUT TO THE OTHER VEHICLES OCCUPANTS AS WELL. FROM THE PROGRESSIVE STATE OF THIS PROBLEM THAT I HAVE SEEN THUS FAR, I FEAR WHAT LIES IN THE AHEAD MILES. PLEASE INVESTIGATE THE PROBLEM ASAP BEFORE IT CAUSES A DEATH, SERIOUS INJURY, OR OTHER PROPERTY DAMAGE. I MYSELF HAVE BEEN LUCKY AND AVOIDED A FEW CLOSE CALLS DUE TO THIS ISSUE. *NM
