Rider stamina

[Sv3n]

Hey guys!

I've been flirting idea with 'rider stamina'.
All these dirt bike games are based bike "simulation" (more or less), but more then half (in real life) is about rider and his stamina and training.
It should not be overly complicated, rather something simple like if u fall, u lose some % of stamina.
At first it slow speed ur ride and how u ride, but at the end it encourages more clean riding.

What u think?
