SPRING,DETENT T20
A gearbox detent spring, Triumph part 57-2106, for the T20 model.
This is a detent spring listed under Triumph part number 57-2106, for the T20 model. The catalog description simply calls it a spring, detent, and another listing ties this same part to a camplate plunger application, which fits with what detent springs generally do in a gearbox — they push a spring-loaded plunger or ball into notches on the camplate to hold each gear selection in place.

We don't have more detail on this one beyond that. If you're chasing gear selection that feels vague or slips out of gear, a tired detent spring is one of the usual suspects, but without more from our records on exact fitment we'd rather have you call the shop and confirm before you order.
The part also shows up in our records as MT57-2106, which is just an alternate form of the same number.
