The Cyclery Spare Plug Holders for Classic Springer Forks
A quick answer to the question where to put a set of spare plugs. These adapters screw into the legs of Classic Springer Forks which feature legs with M20 x 1.5 threads at the upper end. If present, the stock top covers are omitted. Of course, you can use them with original forks, too, if you tap the legs.
