M20 based sprint thing on ebay

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
