GEARBOX SPROCKET 22T - 5 SPEED TRIUMPH 72-ON - UK

22-tooth gearbox mainshaft sprocket for the 5-speed Triumph gearbox, 1972-on, UK spec.

PN · 57-4782/22
Available in 6 versions:

This is a gearbox sprocket with 22 teeth for the 5-speed Triumph gearbox used from 1972 onward. It mounts on the end of the gearbox mainshaft and carries the final drive chain back to the rear wheel sprocket, so it's a core part of the drive train rather than anything inside the gearbox itself.

The catalog lists this as a UK-spec part, and it's also cross-referenced under SPR-5SP22T if that's the number in your own records. Tooth count matters here — swapping to a 22T changes your overall gearing, so before you order, check what count you're currently running and confirm this is the change you're after.

We don't have much more detail on file for this one beyond what's above. If you're not sure this is the right sprocket for your setup, give us a call and we'll sort out fitment before you commit to an order.
