16T Norton Magneto Vernier Sprocket
A Kingpin Components Vernier Sprocket designed to fit all single cylinder Nortons with 16T magneto sprockets.
Norton used 15T sprockets on their singles until the engine underwent a major re-design in 1948. If your engine is pre 1948 then you will probably need the 15T version which we also sell. However as so many of these engines have been worked on over the years, we recommend you check what you currently have before ordering.
More information on how these work is available in the Vernier Sprockets page.
