Well hey now, here’s something different… This billet aluminum bayonet gas cap will spice up your gas tank while giving you a heavily knurled, no-slip grip to remove your cap, refuel, and hit it once again.

Fits all year ranges of single cap gas tanks (and custom gas tanks) that accept a bayonet / cam-style gas cap, all 1936-64 H-D Big Twin gas tanks (both left and right side), and right side gas tanks on H-D 1965-1972 Big Twins.
