OIL HOSE 1/4X 21
Oil hose, 1/4 x 21, part of the frame/battery carrier/engine shield oil line setup on 1971-1972 machines.
This is the oil hose listed as 1/4 x 21 in the catalog, also shown under the 6mm x 21 alias. It shows up in the frame, battery carrier, and engine shield figures for 1971 to 1972 machines, which puts it in the oil-line routing that runs near the frame and under the seat/battery area rather than at the engine itself.

Oil hose like this carries oil under pressure or return flow between the frame-mounted oil tank and the engine, so it has to hold up to heat, vibration, and years of oil contact without swelling or cracking. If yours is original, it's worth a look for softening, cracking at the ends, or seepage at the fittings.
The 1/4 in. dimension referenced in the description lines up with what's on file, and the 6MM X21 alias is just the metric-flavored version of the same part number in our records. Beyond that, our catalog entry is brief, so if you're not sure this is the exact hose your bike needs, give us a call and we'll confirm before you order.
