Some Regulations and Discussion of Pre-65 Trialing
OK. Well the term Pre 65 trials is a bit misleading now-a-days.
The term was started way back in the eighties, when a group of guys thought it would be a good idea to pull some of the discarded old British trials bikes back out of the sheds, and back into competitive use. The name "Pre 65" was used as this was the natural cut off point, when British built trials bikes faded, in favour of the new bikes imported from Spain. This came about when the great Sammy Miller stopped riding his famous Ariel GOV132, and took up a contract to ride the Spanish Bultaco.
