“On a few occasions my engine kill switch has been inadvertently engaged while riding. The first occasion I was traveling on the interstate in the left lane approximately 75 MPH when I went to press the push to talk button for the cb (which is on the throttle (right) side of the handlebars) and in the process of trying to maintain consistent throttle and engage the push to talk, my hand hit the engine kill switch. This happened at night so I had no clue why all of a sudden my bike turned off. I had cars barreling up behind me as I rapidly decelerated due to the loss of engine. …”
