Re young riders, the Classic Manx has a rule which states the winner must be over (40?) Younger riders still ride, and may have the lowest score. The age rule is to sort the pot hunter from the genuine enthusiast.
Each to their own, but surely it's about getting out and enjoying a day's trailing ? Twin shocks etc compete in their own classes, as I'm sure you know,so whether their brakes / suspension / mapping is better or worse isn't a factor.
You must be a very delicate soul if "bollocks" constitutes a "verbal assault"
Plenty of young riders in the north east and Highland 2 day. And as an aside, can't be much of a weight difference between good twin shock and a 4RT.
