The BSA C15 was BSA’s first four-stroke unit-construction bike. A 250 cc single-cylinder, it was very popular with learners in the United Kingdom because at the time, a 250cc was the biggest engine that beginners could use. BSA also made the C15T (Trials), which opened up access to the dirt. For more information, head on over to bsa-c15.org. This specific example has had plenty of new and upgraded mechanicals, and is ready to ride after a full tune-up including valve adjustment. Find this BSA C15 for sale here on Craigslist in Waukesha, Wisconsin for $2,500.
