Left top cover
Left-hand top cover for the Triumph telescopic front fork, part 97-1646 (also H1646), tied to 1964 fork assemblies.
This is the left top cover from the front fork assembly, listed under Triumph part number 97-1646, also known by its earlier factory number H1646. It shows up in the parts book figures for the telescopic front fork on the T90 and T100SS, and again in the fork figure for the TR6 and T120, all tied to the 1964 model year in our records.

A top cover like this sits at the upper end of the fork leg, dressing up the area where the headlamp mounting brackets and fork top nuts live. It's a cosmetic and protective cover rather than a load-bearing part, but getting the correct side matters since this is specifically the left one.
Because this part only turns up tied to 1964 across our catalog entries, treat that as the year to confirm against your own fork assembly before ordering. If you're restoring a matching pair, check that you're also sourcing the correct right-hand cover to go with it.
