Well I have a BSA MX bike that is the same as the day it rolled out the factory including steel bars and yokes and the same with my Greeves & Bultaco
I only like to do mods that are period
I have watched the Pre65 Motocross change over the years & its not much fun now! (unless you spend ££££££ on a bike)
It doesnt bother me too much what people do or spend, but it would be nice to have a class for standard (pure Pre 65) bikes
