Your question is unclear.

You mentioned an atv rally yet an rt is a bike, yes?

That motor is not designed for highway use or running at steady, high rpms for extended periods of time.

If its 80km of speed up, slow down, rest a little and go again miles, you can ride all day like that, but personally, I would not subject a two stroke motor to a highway style kind of ride for more than a few minutes at a time.
