Norton Piston complete L.H. Standard
Complete left-hand standard-size piston for a Norton twin, from the crankshaft/con-rod/piston engine group.
This is a complete piston, left-hand side, listed as standard size, from the Norton engine records. The catalog places it with the crankshaft, connecting rods, camshaft, and timing gear group, which tells us it's a bottom-end/piston-and-rod component rather than anything to do with valve gear or the head.

The listing says L.H. standard, so this is the left cylinder's piston at stock bore, not a rebore size. Norton twins run separate pistons per cylinder, and this entry is specific to the left side, so don't swap it for the right-hand piston without checking your engine's numbers.
We only have this one catalog line to go on and no partner documentation to confirm bore diameter, ring pack, or gudgeon pin spec, so give us a call before you order to make sure it matches what's in your engine.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
