For me it comes down to having a competitive grid with good looking reliable machines or not. Every one of us would be waiting a very long time for a complete grid of true period bikes that were ready for a good beasting around the TT Course .. look at the discussions we have now, imagine the fuss if every bike had to have true period components and how/who would regulate it all - like it or not the event wouldn't happen, I guess for some that wouldn't be a problem but for me seeing and hearing the bikes works very well. On the other hand if there is a big number of period bike owners/riders who can't get a ride or want to let somebody else ride their bike lets see hands in the air please ..
