The reason they get restored to original condition is because they are rare and worth a lot of money these days...if this didn't happen there would likely be very little of some classic bikes left....dont get me wrong i love customs i even have a Triumph Trident chop but there are so many Harley's and modern bikes out there to build customs out of.That "Gold Star" is mighty fine. Restorers are so lame. Just because it is rare and expensive they love it and call modifying one a sacriledge. If another BSA was rare they would love that. I can buy a Gold Star every day of the week and there would still be plenty advertised for sale.
But there is only this fine chopper with its 16" rear wheel and 21" front. Extended forks and hardtail conversion. I would rather have that then a stupid stock bike.
