Six Hole 'Finned Type' Rear Hub/Sprocket for all Plunger Frame Models - Each

This is a very good, English made, example of the rear sprocket/hub that was fitted to all SOHC and OHV Nortons with Plunger frames, identifiable from rigid framed models as having a different mounting and fins around the drum.

This distinctive sprocket/hub is easily distinguishable from the Rigid/Swinging arm type sprocket, as it has cooling fins around the brake hub and has 6 holes - as the plunger hub has 3 studs and 3 locating pins (the rigid hub does not have holes - it has 3 closely mounted studs instead - see Item 0296 for this item).

This sprocket type has been extremely difficult to find for many years, so I am very pleased to be able to offer such a nice example It should be noted that this type of rear sprocket was also used with plunger Overhead Valve bikes fitted with plunger frames.

The sprocket is to take a 5/8" x 1/4" chain, as per the original
