The TriBSA, or Tri-B.S.A was a custom built cafe racer or off road motorcycle of the 1960s and 1970s. Its name was an union of 'Triumph' and 'BSA' with the purpose to combine the best elements of each marque to give a superior bike. A TriBSA involved a Triumph parallel twin engine installed in BSA motorcycle frame. Although both the BSA A65 and the Triumph 650 twins engines were overhead valve 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 hence the best of both.
The Triumph/ BSA hybrid specials of the 1960's are not as well documented as their Triton cousins but are as equally good in their own right. This example registered on the 8th August 1959 was said to have been a scrambles and road racer in an earlier life. Built from a BSA frame, Matchless front forks with Norton front brake, a Triumph 650cc 6T Thunderbird engine with a later nine stud head and BSA gearbox and chain case. It is also fitted with an alloy fuel tank, chrome wheel rims, new tyres and has Betor gas adjustable rear shocks. Presented in generally good overall condition, it is of 'daylight' running specification and is MoT exempt. It is supplied with its current UK V5C logbook and an old buff logbook dating back to 1969. It has recently received a full check over and is fitted with a new speedometer.
