Tribsa Classic Motorcycles
The Tribsa was a modified Cafe racer motorcycle
of the 1960s-1970s, the name coming from a contraction
of Triumph and BSA (the Birmingham Small Arms
Company) - the two brands of motorcycle combined.
The intention was to combine the best elements
of each to give a superior bike to either. The
usual practice was to take the Triumph parallel
twin engine and use it to replace the engine
on a B series BSA motorcycle which were generally
single cylinder. The Triumph engine gave good
performance and reliability and could be tuned
easily for greater power.The Tribsa was an alternative
to the Triton which was a Triumph engine in
a Norton "featherbed" frame.
