I will need to look at mine, but I do a good amount of 2-tracking and boon docking. Both of those are generally speaking at very low speeds, to stay safe. On two tracks, seldom do I go over 30, especially if it is untracked. I am reminded of a guy who was killed because he hit a downed log on an untracked road, flipped and believe broke his neck. Boon docking, you stop a lot, evaluate, then go heavy throttle for usually less than a minute. All of this adds to a lot of idle or low speed time.
I do recall keeping track with the Polaris app on certain rides, where we just trail rode. We were hauling and averaged around 40 mph if I recall.
