FORK TUBE 71-72 TRI/BSA
Chromed front fork inner tube for the 1971-72 conical hub forks, PN 97-4007 (aka H4007).
This is the fork tube for the 1971-72 conical hub front end, used across the Triumph and BSA 650/750 twins and triples of that era. The catalog carries it as 97-4007, with H4007 as the older legacy number for the same part.

The fork tube is the chromed inner leg that slides inside the fork's lower sliders, carrying the front wheel's up-and-down travel and giving the stanchion surface the seals ride against. On the conical hub forks these two years used a specific tube, different from the earlier and later fork designs, so it's worth checking your fork type before ordering rather than going by year alone.
We show this one appearing across a couple of catalog listings tied to the 71-72 conical hub front end. If you're not sure whether your bike has the conical hub setup, give us a call before you order.
