For sale is my 1965 Mandarin Red BSA Cyclone road model.  This is the A50 500cc dual carburetor engine.  This moto was produced for one year only; a limited number were manufactured and a very limited number were imported to the U.S. as the A65 650cc was more in demand.  As far as I have been able to determine there is only one other survivor in the U.S. and that is in a private collection. I believe this to be the only one still on the road in original condition.  I have no provenance for this moto; I was told by the former owner, Bob's Classic Bikes in Indiana, that the engine had been recently rebuilt (i.e., probably approximately 5 years ago) and the bike performs in line with his report.  The moto has been ridden only approximately 200 miles since then.  The speedo has recently stopped working; I believe this to be a cable issue.  The moto was converted to a Tri-Spark 12 volt electronic digital ignition system earlier this year by Terry Parker of Parker Performance in Maryland to enable it to be a daily runner.  As such, it kicks over easily and reliably.  None of the original wiring was removed and the original points, condenser, etc kept if a future owner wishes to restore the moto to its original 6 volt condition.  The seat is almost certainly re-done but is accurate in its details.  Period correct handlebar mirror.  As far as I know, the moto is otherwise original.  There are  two small dings in the fiberglass side-covers; I have tried to show them in the photos.  I have recently had my L3, 4, and 5 vertebrae fused and am now having to rely on electric starters.  Two shop manuals included. Who would like to be the next custodian of this piece of rare motorcycle history?

  • Gary: After a thorough search of both carbs I cannot find any number on either. Sorry.
  • They would be on the mounting flange. Maybe one has it and not the other. They are typically in the area where the stud and bolt are
  • Gary: I cannot locate a number on either carb. Should it be on the top between the bolts near the gasket?
  • Thanks for the number info. Can you provide the number stamping on the top of the mount portion of the carbs. It is likely either 376 or 389.
  • May I ask which part of Va the bike is located? I live in central Va.
  • Gary: the frame number is A50B7477 and the engine number is A50D262. As you may know, frame and engine numbers did not necessarily match at the time.
  • What are the engine and frame numbers?
  • Roper, The 200 miles on the speedo represents the approximately 90 miles put on the bike by the previous owner after the rebuild and the mileage I put on prior to the speedo ceasing to record. I put about 150 miles on the moto in total, so probably about 240 miles since the rebuild all told.
  • It says approximately 200 miles since engine rebuild.
  • The mileage on this moto is unknown.
