FRONT MASTERCYLINDER ASSEMBLY 73-78 SS LFH (STANDARD BORE) 13MM
Complete front brake master cylinder assembly, 13mm standard bore, stainless barrel, for 1973-78 disc-brake front brake systems.
This is a front master cylinder assembly, the unit that sits at the brake lever on the handlebar and pushes fluid down the line to work the front disc brake. The catalog description calls out a 13mm standard bore and a stainless-steel barrel, which is the version built to hold up against the rust and pitting that plagues the plated originals in this spot.

The catalog places this assembly in the front brake system on disc-braked machines from the 1973-78 era, and the alias 60-4102S reflects a later stainless-barrel revision of the same part number. Records also show it replaced an earlier factory number, 4222-979, so if your parts book or an old invoice lists that number, it's the same physical unit under a different name.
This is the complete master cylinder assembly, not just a rebuild kit, so it's a straightforward swap for a tired or leaking unit. Check the bore size against what's currently on your bike before ordering, since the catalog specifies this as the standard 13mm bore version.
