So I road dirt bikes and motocross bikes for many years and thousands of miles.
Would I learn very much in a street licensing course?
Oddly, I’ve never sought my M license to date.
That's the background I came from.
My biggest transition was braking from dirt to street and really learning counter steering as an art.
No question in my mind my dirt experience paid huge, huge dividends on the street...but more so on the track.
But yea...I think you'd learn something.
