Post Listing Update: This C&J framed BSA was pulled off of eBay, final sale price unknown.


Back in January we featured a C&J-framed “Horsepower Factory” Honda XR500 racer, however what we have here is a markedly rarer C&J specimen. This is a 1979 C&J Framed BSA B50MX. Not only is this vintage Brit bike said to be in 100% original condition, but it’s practically brand new with only 5 miles on the clock.

While I couldn’t verify this independently, the seller claims they personally spoke with Jeff Cole (of C&J Frames) and were told the AMA Hall of Famer only built between 10-12 BSA B50 frames, which, if true, makes this an incredibly rare machine. The seller states this example was originally purchased in ’79 or ’80 and for one reason or another (apparently the first owner strapped a 38mm Mikuni carb on?) this specimen has sat mostly dormant for the last four decades, though it did receive attention (and have its stock carb reinstalled) in 2010 by Bill Getty of Perris California’s JRC Engineering.

While it’s no show-quality bike, this Beezer is in pretty great condition for a forty-year-old off-road racer. The red paint on the frame looks pristine and the polished tank still bares its factory logos. You can find this 1979 C&J Framed BSA B50MX for sale in Malibu, California with an unmet opening bid of $13,995
