1960 Tribsa BSA 750cc


The Tribsa, or Tri-B.S.A.,was a custom built café racer or off road motorcycle of the 1960s and 1970s. Its name was an amalgamation of Triumph and BSA. The purpose was to combine the best elements of each marque to give a superior bike to either.


A Tribsa involved a Triumph parallel twin engine installed in BSA motorcycle frame. Although both the BSA A65 and the Triumph 650 cc twins engines were overhead valve (OHV) units, only the Triumph had twin camshafts, which facilitated tuning for greater power output. The BSA frame was a duplex-cradle design which was considered stiffer and stronger than the Triumph’s single downtube item.


This Tribsa, fitted with a 750cc Bonneville motor, has come from a private collection and was regularly raced by the previous owner. Said to be a fantastic bike to ride, this is a very nice example of best of breed in the 1960s. Not to be missed.
