Looking to rebuild your Triumph 650 / 750 cylinder head using the best quality valve components on the market today? Look no further as our new USA made Kibblewhite valves and BRITVALVE valves are the quality parts you should be installing.



Kibblewhite valves come in (2) types of finishes. White Diamond comes in a natural stainless steel finish and Black Diamond are coated stainless steel valves. Kibblewhite valves are produced from EV8 one-piece forgings making them durable and superior over any original Triumph valve. Both are CNC machined right here in the USA.



BRITVALVES are the newest Triumph valves on the market today. Very similar to those manufacture by Kibblewhite, BRITVALVES valves are high quality and also very affordable. BRITVALVES come in a black coated finish just like Kibblewhite Black diamond valves.


Both Triumph Kibblewhite valves and Triumph BRITVALVES will fit all Triumph 650 unit twins (Bonneville & T120 only) from 1963-1972. Fits all Triumph 750  models (Bonneville, T140, T140E & TR7) from 1971-1982. Also fits Triumph Unit TR6 models from 1967-1972 (with the correct cylinder head). Please refer to your parts catalog for proper fitment.
