Yep. It is time and distance. I forgot the timer part in my last post. The important part is that they won't time out when stopped. The bikes that I had with that feature just worked fine - so I never much thought about how they worked. It is like when you twist the throttle, you don't think about the various sensors, the FI computer, the throttle bodies, etc. You just know that twisting the throttle brings on more power.
This self cancelling turn signal technology has been around since at least the mid-eighties. It is not new, and it is proven. It would cost next to nothing for Suzuki to put it on our Burgman's. I think it is often limited to the top of the line touring motorcycles as a sales incentive more than anything else. Hey, if you buy this $12,000 touring bike you get self cancelling turn signals, along with reverse gear and a hydraulically deployed centerstand! It's marketing BS.
