Norton Commando

ABOVE: 1974 Norton Commando 850 Roadster.

While the Commando was a direct descendant of the the Norton Atlas & the Dominator line before that, the Commando was definitely not evolutionary. It was revolutionary, a true game-changer. Not because of some amazing new engine, not because it was all that faster than the model it replaced. It was because the new Norton Commando solved, in one brilliant design concept, the biggest problem that had been nagging every British motorcycle manufacturer for the past 20 years. Vibration!

The new Norton Commando came with a brand new frame, a whole new idea for a frame, one that isolated the engine & its vibration, from the rest of the bike via rubber mounts. It was called Isolastic Suspension & it immediately made the Norton Commando a runaway hit! Norton Motorcycles was now free to extract the kind of power the big twin was capable of without worrying about shaking the machine & rider to pieces!

1968 Norton Commando Fastback. Norton motorcycles became known for their loud & sometimes outlandish color schemes.

Mind you, it must have taken a lot for Norton to be willing to ditch the venerable, proven Featherbed Frame, the single most important piece of hardware Norton had ever produced & the one that put them on the map. The Featherbed was light, strong, rigid & above all, was renowned as the best handling frame on the planet. Why scrap it?

In the end, the very thing that gave the Featherbed its amazing handling, its rigidity, helped to do it in. So stiff a structure tends to transmit engine vibrations even more acutely & as displacement & output continued to climb, the vibration was really becoming a problem. Like Triumph & others, Norton fiddled with various tweaks to the engine internals (ie: compression ratios, flywheel weight, crankshaft balance factors, etc.), but nothing really seemed to work. When it started out life as a mildly-tuned 500cc twin, the vibration really wasn’t that noticeable. But as capacity grew to 600cc, 650cc, then 750cc, twin carbs sprouted, compression ratios climbed & revs increased, the vibration just got worse & worse. It was inevitable, considering those two pistons rising & falling together, flying back & forth thousands of times a minute. They didn’t want to detune the engine to tame it. If anything, they wanted more power. Norton needed to keep their bikes competitive with Triumph and BSA. What to do?

ABOVE: 1972 Norton 750 Commando Fastback. A front disk brake actually arrived partway through the 1972 model year. Some early ’72s still sported this fine TLS front drum, which utilized the same drum as the old SLS front brake from the Norton Atlas. Waste not, want not.

ABOVE: 1974 850 Norton Commando. Another innovation in the new Commando was the slanted cylinders. This was essentially the same engine as used in the Norton Atlas 750, but instead of being vertical like the Atlas, they tilted the Commando engine forward before mounting it, to give it a distinctive, more modern look. It worked.

The Norton Commando was a direct result of the collapse of AMC (Associated Motor Cycles, Ltd) who owned Norton, Matchless & AJS, among others. AMC’s stable of brands was acquired by Manganese Bronze Holdings, who also owned Villiers, and the new company was renamed Norton-Villiers. And they had a plan.

The Matchless & AJS lines were struggling, but Norton showed great promise. Thanks to the Featherbed, the Norton Dominator & Norton Atlas had earned a reputation as fine-handling machines with good power. So, the decision was made to kill off the Matchless-AJS twins at the end of the 1966 model year & concentrating all resources on creating an entirely new motorcycle, an entirely new ‘type’ of motorcycle.

The result was the 750 Norton Commando, the new type was that of Superbike. It was the first! The secret was the Isolastic Suspension. It freed engineers to extract all the power & revs out of the powerful twin. It was such a resounding success that it was named Motorcycle News’ “Motorcycle of the Year” 5 years running.

Norton Motorcycles spun 6 different models off the same basic machine. The Roadster (which was the basic Commando); The Interstate (designed as a long distance touring bike); The Fastback (with special seat & fender); The Hi-Rider (a hideous factory chopper); The Production Racer (a street-legal mildly-tuned GP bike); & The Interpol (the police version).

Early Norton Commando MkI’s had frame bending problems that were solved with the introduction of a new, but very similar frame. In 1972 the 750 ‘Combat Engine’ was introduced as a raced-tuned engine that actually only produced 5hp more than the stock mill. But the Combat proved fragile, having been pumped up to its practical limits of performance, it was easily pushed too hard. Replacing blown Combat engines became the factories preoccupation for the latter part of 1972. The Combat was dropped for 1973.

The Commando was wildly successful, although Norton could never produce the volumes of bikes that Triumph did at the time. Demand outstripped supply, making them even more sought-after. The mystique continues today as Commandos are more popular than ever with collector & enthusiasts. Motorcycle Auctions bristle with various versions of the Norton Commando. They’re certainly fast enough & modern enough to keep up easily with todays’ traffic, making them an even better collectible. As with virtually all mass-produced Classic British Motorcycles, the Norton Commando is truly undervalued & underpriced in the marketplace. Buy one now before the world realizes that they can have an awesome machine like this for one third the price of a new Harley. But, with way more exclusivity.

ABOVE: 1974 John Player Norton, aka: JPN.

The Norton, always clever and resourceful, cut a sponsorship deal with John Player Cigarettes for their road racing efforts in the early 1970s. It was such a good idea that they homologated it into a street bike. Known as the JPN (short for John Player Norton), it was introduced to a stunned public in 1972, no one had every seen a street bike like this before. Today, fully faired road racers are quite common, but in 1972 they were unheard of. While looking the park of a full-on race machine, the street version of the JPN was actually mechanically stock in every way. JPN was basically an appearance package. Oh, but what an appearance! The look inspired legions of sport bike to follow, including another game-changing Honda 750 Interceptor in the early 80’s, a bike that even sported a similar color scheme. John Players are much sought-after today by collectors.

How Isolastic Suspension works

The answer was the brainchild of former Rolls Royce engineer Dr. Stephan Bauer, who thought the Featherbed Frame was bunk. He took a whole new look at the situation. What he came up with was Isolastic Suspension. Essentially, the non-unit Engine/Primary/Gearbox is bolted together into a rigid unit via 2 steel mounting plates that also support the swing arm pivot & the rear rubber mount. There is a front rubber engine mount & a rubber-mounted headstay. In this way, the entire engine package & swingarm are connected to the frame in 3 places & isolated from it via the rubber mounts. The true genius of this system was not the rubber mounts, that had been tried before. Problems always arose keeping the chain aligned as the engine moved around in its soft mounts. Bauer solved this problem by mounting the swingarm pivot (& through it, the swing arm & rear wheel) to the engine so that they moved together as a unit, keeping chain tension & alignment constant. Another fringe benefit is that it gave the vibration a path to the ground & out of the bike. Rigidity was to be assured by a large-diameter 2.25″ backbone. However, the first frames on the 1968 Norton Commandos were actually prone to bending under stress. A new frame was introduced for the 1969 model year that solved the problem & this frame would serve throughout the rest of the Norton Commando’s short, but valiant life.

The new “Donington” Norton Commando

ABOVE: This 2014 Norton Commando 961 Sport shows the new face of Norton. Modern all the way, but instantly recognizable as a Commando.

When the classic Commando went out of production in 1975, a battle over the rights to the name ensued. Ultimately UK business man Stuart Garner, who already owned Norton Racing Ltd acquired the rights to the Norton Commando brand. His new company, Norton Motorcycles Ltd, he commissioned Simon Skinner to design the new bike, and built a state-of-the-art factory in Donington Park, Leicestershire, England to produce them. It took until 2010 for the first production bikes to hit the market, at an initial rate of around 5 to 10 bikes per week. These, the first Norton Commandos in 30 years were available in three models: The 961 Sport, 961 Cafe Racer, and the 200-unit limited edition 961 SE.
