Mexico, that Third World country to our south, is run by people who use the rules to benefit themselves and their friends. They system is designed to protect them. Everyone else has to go somewhere else to take advantage of opportunities and for the freedom of doing what they want away from an oppressive and unfair system. Just a passing thought.
Tires. M/C tires "used to have" a lifespan of 5 years written into the rules. Cars (cracked sidewalls, exposed cords and all) did not. It is my sincere hope the Aftermarket/OEM engine cases rule in M follows the M/C tire rule. Out of the rulebook and into a future trivia contest: Who screwed M class aftermarket engine case racers in what year and why? Anyway, some innovative and really fast motorcycles are going to need LSR tires someday. Fronts, okay with what's available up to 300. Rears, something more than a shaved ZR. Hopefully they will be available.
