Spindle cap
A spindle cap fitted at the bottom of the telescopic front fork leg, part of the front axle fixing arrangement.
The spindle cap, PN 97-1053 (also listed as H1053 in the older letter-prefix system), is a small fitting that lives at the bottom of the telescopic front fork leg. It shows up across a wide range of telescopic fork figures in the parts books, spanning the T20SS/T20SH, 3TA/5TA, T90/T100SS, 6T/T110, and TR6/T120 fork assemblies, which tells you this was a common piece used across a lot of Triumph's smaller and larger twins during this catalog window.

Its job is straightforward: it caps off the fork bottom where the wheel spindle passes through, part of the fixing arrangement that holds the front axle in place at the base of the leg. It is not a glamorous part, but it does the job of keeping that end of the fork leg finished off and the spindle assembly secured.
We see this part number appear frequently in our records across those seven fork figures, so if you are working on a front end from this era, it is worth checking whether your bike used this style of cap before you order. Bring in your old one if you have questions about matching it up.
