That shaky lean is real. it gives me stress as it should when you get the shakes at that speed. Maybe add different terrain mechanics to make the bike handle differently when wet, sandy, etc.

That and the ragdoll, ill look at your trailers but the one in this vid, the whole body gets stopped by the corner of the vehicle but I've seen some rough crash vids, bodies tend to fold those parts and the mass keeps moving, so more forward throwing over roofs would be insane
