“While stopped at red light, as the light turned green, I proceeded to apply throttle with no response. Let out clutch and rolled no faster then 20 MPH while cars were backing up behind me. After rolling at 20 MPH for approximately hundred yards, I was able to pull over in a safe location with out being run over.”

NHTSA complaint #10633060, filed 2014-09, 21,792 miles

“The problem began around april of 2012. When I started the motorcycle, there was no throttle response. The motorcycle will idle at 1000 RPM but the throttle will not work when twisted to accelerate engine. It remains at idle. It has happened several times and I have to disconnect the battery in order to reset the electronic throttle. Sometimes it works, other times it does not. It also happened various times when motorcycle was in motion at speeds of 45 MPH almost causing me to get struck on highway from behind by another vehicle. …”

NHTSA complaint #10478161, filed 2012-10, 7,550 miles

“Accelerating from a stop up to speed when lost throttle response, engine would not go above 1500-2000 RPM. Was able to limp to the side of the road. I shut bike down and waited a minute and restarted it. It started up and ran as normal. Talked to my local dealer and made them aware of the problem. They seemed very familiar with this issue and said to bring it in and they would give me a cost to fix. This seems to me to be a severe safety issue that should be on a manufactures recall. What if I were trying to get on the interstate and lost the ability to merge .”

NHTSA complaint #10544039, filed 2013-09, 9,300 miles

“I was riding home from marietta, georgia on interstate 575 and had the cruise control engaged. Suddenly and unexpectedly, the cruise control kicked off and I began to decelerate. I was positive that I had not hit the clutch or either brake, any of which would have disengaged the cruise control. When I attempted to accelerate, once again, I found that the engine had gone to a rough idle and that my throttle was unresponsive. In other words, the engine would not accelerate at all. Fortunately, I was in the outside traffic lane and was able to pull into the emergency lane without any difficulty. …”
