Kickstart crank – complete assembly
Complete kickstart crank assembly for the gearbox, part number 57-3721.
This is the complete kickstart crank assembly, listed under Triumph part number 57-3721. It's the arm that carries the kickstart lever, pivoting on the gearbox cover so the rider can swing it out and stab the gear teeth into the mainshaft pinion to fire the engine over.

Being a complete assembly means you're not just getting the crank arm itself but the pieces that go with it as sold together under this number. Our catalog record only ties this one appearance to 1973, so if you're chasing a match for a different year, give us a call and we'll sort out whether this is the right one before you order.
The figure it comes from covers the gearbox cover, gearchange, and kickstart crank together, which tells you where it lives on the bike but not much else about it. If your kickstart lever or the crank underneath it is worn, bent, or missing teeth, this is the part number to work from.
