I will support anyone who wants to keep twinshock trials bikes as period machines. They were produced by the factories and sold to competitors - those that could afford them - as the latest technology at the time. The worlds best riders were using them, albiet with a little tweeking no doubt, but essentiallly as we bought them. Same as todays trials bikes are available to the public. I bet in thirty years time there wil be a similar debate over 'period' Cabestany Shercos! I personally would not like trials to go the same way as road racing for example where it costs you
