I would have to say replacing the rubbers in a Triumph clutch hub center is probably one of the most feared and oft-neglected tasks of a British motorcycle owner. These brand new clutch hub centers solve that problem, as they are complete with new rubbers and ready to install! No more torching it and trying to get the impossible stock flat head screws out and wasting hours prying old rubbers out and trying to squeeze the new ones in. This complete, Made in the UK, clutch hub shock absorber assembly fits all unit 1963 - 1982 Triumph 650 and 750 c.c. model motorcycles including T120, T140, TR6, TR7 etc as well as unit twin Triumph 350 and 500 c.c. models fro 1963-1974 and BSA A50 and A65 1966-1972.
