Footnotes

  • As well as Brough Superior's wide use of JAP and Matchless engines, and the less well known application of MAG and Austin power plants in their motorcycles, probably the rarest fitment was that of the 998cc Barr & Stroud sleeve valve. Two examples were produced, both in 1923; the first for A.D.S. Barr was fitted into a Mark I frame, the second was manufactured approximately one month later and appears to have used an SS80 frame. The Mark I based machine made its public debut, with sidecar attached, in the 1923 Scottish Six Days' Trial only to retire on the first day with a clutch problem. It met the same fate when it competed in the 1924 SSDT.

    Noted for their 'silent and sweet-running', due to lack of conventional noisy valve train, and having the unique design feature of a horizontal split crankcase to ease changing of con rods, pistons and flywheels, Barr & Stroud singles and twins were fitted to other makes including Grindley Peeless, Omega, Rex Acme, Sparkbrook and Zenith.

    This engine offers the possibly unique opportunity to recreate one of few Brough Superiors which no longer exists and to bring this important piece of the brands history back to life.
