WCBR-BSA B25 Enduro...
We bought this BSA in 1992 and it sat for some time... this box-o-parts project began in late 1993 and we built a bike that we think BSA should of built in 1971.  With that said, we've had some fun with this bike too, in its first race at SandHill Ranch, during the  Tommyville GP in 1994 with Mike Green aboard, it finished up front!.
These two photos are from April 2005 at Carnegie Cycle Park and show Richard Green (16) in his first ever AHRMA MX. He finished 3rd in Classic 250/Novice.
