BSA Throttle control cable
A BSA throttle control cable (40-8657) running from the twistgrip to the carburetor.
This is a throttle control cable, catalogued as 40-8657. It shows up in the parts book under the PETROL TANK, TWINSEAT AND CONTROLS figure, which is where you'd expect it: this cable runs from the twistgrip on the handlebar down to the carburetor, and it's what opens the throttle when you roll the grip.

The manufacturer tag on this one says BSA, and the catalog listings that reference this number back that up, naming BSA singles rather than anything from the Triumph lineup. If you're sourcing this for a Triumph twin, double check the number against your own parts book before ordering, since this looks to be a BSA-specific cable.
We don't have a lot more written down on this particular part beyond the figure and the catalog rows it appears in. If you're not sure it matches what's coming off your bike, give us a call and we'll sort out fitment before you order.
