Yea this things nuts. Good BSA m20 sprint/race thing for grabs. BSA m20/m21


  1. i own this now,got her in a deal,she does 127 mph ish,we are going to get her racing again.

    1. Hi there
      Have You had it at speed yet? I wondered if it was really fast when I saw the ebay ad, some of the m20 guys were debating its power output etc. What mods does it have? I see a spacer at the base of the barrel. Nice one cheers

  2. she is 50 ish bhp nowdays, bored out to 750 with Norton clutch and b31 frame, still in garage but I havnt forgotten her
