Why the FIM decided there was a need to take the top level of this incredible sport back to the ole days is beyond me.
The skills have advanced far greater than any other motorcycle sport that is contested. The machinery is top notch, joe average can buy a similar bike to that rode in the top level of competition. Let the best in the world do it in the manner they have been raised and trained.
If the club level wants to change it up, by all means go ahead.
If this sport had existed as no stop all these years, there is NO WAY the skills would have progressed to the level they have.
