Norton Piston complete R.H. Standard
Complete right-hand standard piston for a Norton twin engine, PN 063339.
Part number 063339 is a complete right-hand piston, standard size, for the Norton engine listed in the crankshaft, connecting rods, pistons, camshaft and timing gear section of the parts book. This is a Norton part, not a Triumph one, so if you're working on a Triumph twin this isn't the piston you're after.

The catalog lists it as R.H. Standard, meaning it's the right-hand cylinder's piston at standard bore, with no oversize noted. It shows up in the parts book across 1971 to 1972, and that's the extent of what our record tells us about which specific model it belongs to.
When you're ordering, confirm which side of the engine you need and check your bore size against what's actually in the barrel before assuming standard is correct.
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.
Sorry if we got something wrong here. If you think this information isn't correct, .
