1976 CB750 SOHC with period Seeley Alloy tank and Seat unit, Italian flanged alloy rims, bespoke pea shooter (Dunstall style) exhaust system from Carpys Cafe Racer in the USA and various other nice touches.  Rides really well and drilled discs give much better stopping power than I remember from my original CB750F1.  Straight bars make for a nice riding position too.
