This 1966 Norton Atlas 750 was restored and modified in the style of a Dunstall Domiracer in the 1980s. The seller purchased the bike approximately five years ago from a New York-based Norton collector and the restoration was carried out by former Norton dealer Ron Fratturelli. A number of Dunstall catalog components are fitted as outlined below, and power is from a modified 806cc parallel-twin paired with a 4-speed gearbox. This Norton is now being offered in Washington with a clear Massachusetts title.
Paul Dunstall, a British motorcycle racer turned specialist tuner, offered his first complete catalog in 1966. It enabled customers to outfit their stock Norton, BSA or Triumph motorcycle with a variety of performance parts. The Featherbed-framed Norton 88 S/S, 650 S/S, and 750 Atlas were Dunstall’s main focus prior to the release of the Commando model.
This bike is equipped with a “Dolphin” fairing and detachable silver lower side panels. It also features a racing seat and pin striped 5-gallon fuel tank. A few imperfections are present in the finish, including a crack in the upper fairing and some spider-webbing on the lower section of the side panels.
Aluminum GP-style fenders replace the heavy chrome-plated factory items, and a set of rubber gaiters are fitted on the Roadholder fork. The factory hubs are laced to a set of shouldered Borrani aluminum rims, and the front brake utilizes a modified SLS plate with a cooling scoop and vents. An older set of Avon tires are currently fitted.
A Smiths tachometer and associated drive assembly have been added. A 150-mph speedometer, also from Smiths, is mounted to its left, and closeups of the Dunstall stampings on the clip-on handlebars and headlight brackets are provided in the gallery below. The 40 miles shown on the odometer are believed to reflect the distance covered since the restoration was completed, and the seller has added just 10 miles over the last five years.
The parallel-twin engine is reportedly equipped with a number of period Dunstall components, including a ported and polished cylinder head, camshaft, and a set of oversize high-compression pistons. Displacement is a reported 806cc. Induction is through twin Amal carburetors mounted on finned intakes and equipped with float bowl extensions and velocity stacks. The exhaust system is comprised of twin, swept-back headers and a pair of Dunstall-stamped silencers.
The bike has been primarily stored and displayed for the past five years, and a tune-up, fresh fluids, and a battery are required. The seller recently changed the oil, adjusted the clutch, and checked the valves.
