SOHC Ribbed Outer Timing Cover - With Rev Clock Boss (Magnesium 'Works' Type)

Product no.: 0322 1X04(RM)

November 2020: New Batch Now Back In stock

This is the rarest of all timing covers - the pre-1938 'Ribbed' type outer timing cover, but made in magnesium. As far as I am aware, there were only a handful of these covers made, for the 1937'ish Big Plunger Works race bikes. A nice addition if you have a pre-war competition Inter or early Manx and like the ribbed type cover and want to give it that special touch.  They are also very light!
