Dumbest thing I’ve heard. So because someone is 6’4″ and 190lbs they aren’t fit, of high caliber, semi-pro or professional capable? They don’t drive often or shouldn’t be competing nationally? Your assumption about weight is incorrect. Not everyone is short and fat with the ability to lose weight to get down to 175lbs or less.
We need to worry about what supports the sport with the most numbers possible. Who cares about a few extra tenths quicker when it’s all relative. Everyone is at same weight! As Richard Petty put it speed is irrelevant, it’s about the competition. Last thing karting needs to do is put rules in place that limits it’s growth potential, even at the national level.
