Yup, both of these work at speed

'Twas an accident. I had an hour earlier opened the seat and as most of us know the kill switch often gets bumped. I appear to have only bumped it 99% so was still able to ride but an hour later it vibrated to 100% killing it (might have been the steep gravel road I had just ridden up).

Attached graphs (15 secs) show cruising at 80kph then the kill coming on. I released the throttle when I felt the change in performance. I then noticed the kill (dash light and switch position) so turned it off. Pressed the starter which worked and blipped the throttle and released it. Then continued to slow down as I pondering things. (After the end of the graph I rolled to a stop at the side of the road with the engine idling while I thought about what had just happened).

PS, can't remember for certain but had probably gently applied the brake when pressing the starter
