| Was Vehicle Towed: - | Description of the Complaints: 2007 yamaha r1- the other day i was in rush hour traffic on my motorcycle. i was driving at approximately 45 mph in second gear when the car next to me began to merge over on me. i tried to accelerate to avoid a collisions but my bike did not immediately respond to the throttle. fortunately i was able to maneuver out of the was of the merging vehicle.. the lag in the throttle response seemed very strange to me so i decided to test the bike by recreating the scenario. my finding were, if i ride the motorcycle in 2nd gear at approximately 48 mph (5500 rpm) and try to quickly accelerate (ie- to avoid a collision,,,etc), the bike will lag and accelerate slowly. this defect was consistent each time i tested the bike. all other gears and speeds, acceleration was perfect. before contacting the dealership about my problem, i decided to do some research online. i did a google search for 2007 yamaha r1 lag, and to my surprise, i got countless results on the topic. apparently the issue is found in all 2007 yamaha r1s in the u.s. now, being an experienced rider, i can surly say that 40 to 50 mph are very common speeds for a motorcyclist who travels city streets. and its a fact that acceleration along with proper braking and maneuver ability, are key components to riding a motorcycle and avoiding life threatening situation while in traffic. the yamaha website clearly states,,,the yzf-r1 uses the ycc-t fly-by-wire throttle system for flawless response under all conditions. yamaha chip control throttle controls a 32-bit ecu fuel injection system for super-responsive, smooth, instantaneous power delivery. this is far from truth and yamaha needs to address this issue. *jb |
