Summary[edit]
| Description |
The 1968 P11A was the second version of the 750cc Norton Atlas-powered scrambler with a Matchless G85CS Reynolds 531 frame made for US cross-country racing. To suit it for street cruising as well, the P11A has a roomier seat than the original 1967 P11 and pillion footrests, while the upswept silencers have detachable baffles. The 1968 machine also carries the Norton Villiers 'green blob' logo on top of the fuel tank. Development The Mark 1 Atlas was launched as the 750SS in the early 1960's. Designer Bert Hopwood’s 497cc Dominator engine was bored out to 745cc to appeal to American market and initially was only produced for export. The styling was also aimed at the US market with high-rise handlebars, small 2.5-gallon petrol tank and valanced chrome mudguards and chain guard. The look was completed with a heavy-duty WM3-18 rear wheel and a Lucas Competition magneto was supplied as standard.[1] The engine had lower compression than the Dominator (at 7.6:1) and was fitted with a single 376 Amal monobloc carb giving 55bhp at 6500rpm. However the design also produced excessive vibration at high revs, so the compression ratio was reduced. The Atlas shared many cycle parts with the last of the Domminator twins and had Norton’s four-speed gearbox and heavy-duty clutch. Electrics were 6-Volt and it had Roadholder forks, adjustable Girling rear shocks and a slimline Featherbed frame.[1] In 1964 the Atlas was upgraded to 12-Volt electrics, gained an extra carburettor and wider yokes. A UK version was launched with flat bars and twin instruments. The Atlas continued to be built until 1968 but by then the Norton Commando had taken over.[1] [edit] Specials and Hybrids Specialist tuners such as Dunstall produced Atlas based racers and the Metisse, and the factory-built Atlas-powered AMC-Norton hybrids even included an Atlas based off-road scrambler.[2] Over seven thousand Atlas hybrids were produced at Plumstead between late 1963 and late 1968 using Atlas engines and the featherbed frame. Most of these machines had complicated designations of numbers and letters instead of names |
