Oil restrictor
An oil restrictor for the telescopic front fork internals, used on certain 1966-1967 Triumph models, also known by its older number H452.
This is the oil restrictor for the telescopic front forks, showing up in the catalog under the front fork sections for the T100C, T100R, TR6C and T120TT models in the 1966-1967 era. It's part of the internal damping setup inside the fork legs, working alongside the fork oil to control how the fork moves through its stroke.

The older parts books list this one as H452, which is the same physical piece as 97-0452 in the modern numbering - if you're working from an old book or a parts list off the bike, that's the number you'd be cross-referencing.
It's a small item but it's specific to the fork internals it's listed against, so it's worth checking your fork setup against the figure listings before ordering, especially if you're mixing components between different fork applications from that period.
