TRIDENT CLUTCH PLATE
Clutch friction plate for the Triumph Trident triple, now supplied under part number 57-3709A.
57-3709 is a clutch friction plate for the Triumph Trident triple. It's one of the friction plates that stack up inside the clutch assembly, and this is the standard replacement part for the triple-cylinder clutch pack. The part has since been carried forward under the number 57-3709A, so if you're working from an older parts book and see this number, that's the same physical plate under current ordering.

These plates wear over time and are a normal service item when a clutch starts slipping or feels inconsistent. If you're rebuilding a clutch pack on a Trident, it's worth checking the whole stack rather than swapping just one plate.
We don't have extensive catalog notes on file for this one beyond the plate itself and its updated number, so give us a call if you want to talk through exactly what your clutch pack needs before you order.
