I agree. This year has been a tragedy already.
I would not want to intervene on something the participants do so willingly & with such enthusiasm.
Perhaps there's an argument to return to the 500cc Senior & 350cc Junior race classes? As it is some of the closest contested races are the Super Twins, a class with a much leveller playing field so bike preparation is absolutely critical but not prohibitably expensive
But if competitors are still willing to risk making the ultimate sacrifice in search of victory in the other capacity classes so be it.
