It got me to thinking, so I looked it up....This is directly from the manual:
"Since this model is equipped with a self-canceling system, the turn signals lights will self-cancel after the vehicle has traveled both about 150 m (490 ft) and for approximately 15 seconds....snip.....NOTE: The self-cancelling system only operates when the vehicle is moving, so that the turn signals will not self-cancel while you are stopped at an intersection."
/end manual quote.
I see nothing about a lean detector either, never heard of that on our bikes.
