The Best of Vintage British Motorcycles

All motorcycle connoisseurs have their favorites.
It’s part of the nature of motorcycling, that certain folks like certain kinds of bikes.
I know several guys who never owned anything but Harley Davidsons.
I personally have owned makes from the U.S., from England, Japan, and Germany.
And I have to say, there is something very special about an English motorcycle.
A reader of mine stopped in and commented recently about how she learned to ride on British made motorcycles…..
I think a lot of us today look at the ready availability of Japanese bikes of every size and description and forget that it wasn’t always like that….
That BSA, Triumph, and Norton actually sold many more bikes in the sixties than did Honda, Yamaha, and Suzuki.
This reader happened to have cut her teeth on two of the great British bikes of the decade– the Triumph Bonneville , and the Norton Commando.
I replied that I had learned on a friend’s BSA Triple ( ummm.. not one of the best bikes ever, but certainly a great period piece ) and that it was a pleasant surprise to find someone else who appreciated Brit Bikes.
I think it’s a mark of good taste, for certain.
Now, some of you might be saying that Brit Bikes always seemed to require a bit more attention…, a bit more tweaking…., and a lot more retightening all the time.
Yes, they didn’t seem to be all that well constucted sometimes, but when you got a good one, well……………………………….. watch out, baby.
And the look —
…..nothing in the sixties really looked as good as a Norton ,
nothing was more fun to ride than a BSA,
and nothing made a better chopper than a Triumph .
Oh yes,
and one more thing —
In the early fifties,
………….. nothing was faster than a Vincent Black Shadow.
Vincent Black Shadow 1950
Vincent Motorcycles
HRD was a British motorcycle manufacturer founded in 1924 by Howard Raymond Davies, who had done some motorcycle racing and wanted to develop a more reliable bike for that purpose.
The company had some difficulty penetrating the market, and in 1928, the company ended up in the hands of a motorcycle designer, Paul Vincent, who called the new company ‘Vincent HRD’.
The earlier HRD bikes had a racing pedigree, and Vincent decided to build on that.
At first, the Vincent HRD’s used a single cylinder JA Prestwick (JAP) engine built on a Vincent cantilever frame… but after a very bad showing at the 1934 Island of Man Tourist Trophy races, Vincent switched to engineering their own engines.
This proved to be an excellent decision.
Chief engineer Phil Irving had been developing several novel concepts, and Vincent HRD put them into production.
These included the three wheeled “Bantam” , the groundbreaking single cylinder 500cc OHV “Meteor” engine, and the 998 cc, 47.5 degree V-Twin with 6:8:1 compression – the 1936 Series A Rapide.
After WW II, Vincent HRD entered the American market, abandoning the HRD labelling in order to avoid confusion with the largest selling American brand Harley Davidson logo (HD).
In 1948, Rollie Free exceeded a speed of 150 MPH on the Bonneville Salt Flats on a specially modified Vincent Black Lightning.
Post war offerings in America were distributed by Indian Motorcycle dealers, and included :
The Black Shadow, with a series-c 998cc V-Twin Rapide engine, produced 54 horsepower and 125 MPH.
The Black Lightning, with a mostly aluminum V-Twin, lightweight racing version of Black Shadow.
The Comet, and the Meteor, with single cylinder 500cc engines, along with a racing version the Grey Flash, with an Albion gearbox.
Several touring models were introduced in the early 1950′s:
the Black Knight, which featured a removable wrap around enclosure for weather protection,
and the high-end Black Prince, an upgraded Black Shadow also with the weather enclosure.
The last Vincent motorcycle came off the production line in December, 1955.
BSA — Birmingham Small Arms Company, produced a full range of motorcycles between 1910 and 1972.
They produced their first all-BSA model, with 3 1/2 hp, at the 1910 Olympia Auto Show in London, and subsequently sold out their lines the next three years.
They had bought British Daimler for automobile engines , and some of the plant was put to work on motorcycle engines.
Soon, in 1919, they were to develop their 50 degree V-Twin 770cc side valve Model E.
The line steadily improved throughout the pre-war era, and several models of varying size and power were offered, from a “B series” 249cc, “R” series 399cc, “W-series” 499cc, “M-series” 596cc, “Y-series” 748cc, “E-series” 771cc, and up to the “G-series” at 985 cc.
Check out a page from their 1934 Catalog:

BSA produced more than 120,000 M-20 500cc and M-21 600cc motorcycles during WW II.
After the war, BSA saw a boom in demand, and they soon acquired several smaller motorcycle companies, including TriumphAriel andNew Hudson, to help meet the production needs.
Their most popular models in the fifties and sixties were :
A-50 Royal Star 500cc
A-10 Golden Flash 650 cc
A-65T Thunderbolt 650 cc OHC
A-75R Rocket Triple 750cc ( three cylinders)
B-44 Shooting Star 441cc ( motocross)
Tribsa — a BSA A-65 frame with a 650cc TR-6 Triumph engine. (motocross)
D type Bantam (ranging from 125 to 175 cc)
BSA also manufactured the DandyBeagle, and Sunbeam brand scooters.
BSA found it increasingly difficult to compete with the cheaper-to-maintain Japanese models in the 1970′s, and soon faded from the market…
The last English made BSA badged motorcycle came off the line in 1972.
Triumph is one of the only pioneering manufacturers of English motorcycles still extant.
Somehow, they survived the bankruptcy of their parent company BSA in the 1970′s,
…. and it’s own, when Norton-Villiers-Triumph (NVT) went under in 1982—
……………. and are currently producing a beautiful range of excellent motorcycles.
Triumph Engineering Company started making bikes in Nuremberg around 1902…
… but the first British made Triumph was produced in Coventry in 1904.
As you can imagine, this setup got kinda tangled up during and after World War I –
…. and the company’s history is a bit on the convoluted side.
Suffice to say that the Model H Roadster– “The Trusty Triumph” made the company’s reputation for quality, and the company grew quickly after the war.
In 1937, Triumph released the ground breaking 5T Triumph Speed Twin 500cc model…
….. and this bike served as a basis for all Triumph Twin models until 1981.
Also around this time, a lighter and faster 500cc machine, theTriumph Tiger 100 , with a top speed of around 100 mph, made its’ appearance.
The Coventry plant was destroyed during the Blitz ( as was most of Coventry) and post war production was relocated to the West Midlands.
Triumph developed a touring motorcycle in 1948, based on the Speed Twin, mostly for the American market, called the “Triumph Thunderbird” –
This powerful little bike proved very popular with American customizers of the time…..
In 1955, a specially modified Thunderbird with a GP racing type twin carb head, dubbed the “Wonderbird”, held the speed record for motor cycles until 1970.
A stock 1950 6T-Thunderbird was also the bike that Marlon Brando rode in the movie “The Wild One” .
BSA acquired Triumph in 1951…
In 1959, a double carb setup was put on the 650cc Tiger T-110 —
…….. and !voila! hence came the famous Triumph Bonneville .
The parallel-twin four stroke 650cc engines on the Bonneville T-120, and later the 750cc on the T-140, were both durable and powerful, and Bonneville soon became the best selling Triumph model in the American market.
It has become somewhat of an icon for the Triumph line ,
….. and many of us mature bikers here in the States remember that bike almost reverently.

Ariel 1939
Ariel, based in Birmingham, started selling motorcycles in 1902, with their first model producing about 2 hp from a 239cc two stroke Minerva engine.
Several improvements were made in the line until, in 1910, a 498cc White and Poppe 4 hp engine, originally made in Coventry, and then in-house, was used, and proved so durable and powerful that it was a mainstay of the Ariel line for 15 years.
In the 20′s, engine offerings increased , with a 249cc, 586cc and a 992 cc added, along with drum brakes, hardier wheels, and enclosed chain drives, to replace the belt drive of previous models.
In the 1927 , under the direction of former JAP head of engines Val Page, Ariel replaced the older style White and Poppe engine with an advanced ‘hemi’ overhead valve design, which produced more power, was quieter, and more efficient…
Another engine introduced around that time was Edward Turner’s concept for a big OHC four cylinder design called the “Square Four” , an idea that had been previously rejected by BSA, and it was used on a Ariel bike of the same name.
This engine caught the attention of the motorcycling world , and the square four engine would become synonymous with the Ariel line.
One thing was obvious from very early on, Ariel Motorcycle would be about large bikes, and powerful engines.
Their most popular bike in the thirties, however, was called the “Ariel Red Hunter” — a nimble single cylinder, dual valve, OHC sport bike offered in 250cc, 350cc, and 500cc configurations… the 500cc could develop about 25hp , with a top speed of 85mph.
The Red Hunter sold so well, Ariel was able to purchase competitor Triumph.
Between 1931 and 1959, Ariel produced a “Square Four” with a large 997cc, 8 valve, 4 stroke, 45hp model dubbed the ” Squariel ” — as it improved over the years, it eventually would reach the 100 mph top speed mark. ( ’4G’, ’4H’ – prewar , ‘Mark I’ 1949-1953, ‘Mark II’ 1953-1958 )
During WW II, over 42,000 Ariels were produced for the war effort, including the “W/NG350” .
In 1944, BSA acquired Ariel, and continued manufacture.
In the fifties and sixties, Ariel’s technology was outdated, their styling looked old fashioned to many, competition was very tight, and popularity waned.
They produced several smaller displacement bikes during this time, “Ariel Leader” 250cc, between 1958 and 1965, and also a 250 cc “Golden Arrow” in 1963.
Ariel 250 Leader
The newly designed 1958 “Ariel Leader” was a beautifully thought out machine, with wrap around panels that concealed much of the workings, and looked almost too modern — it came with full instrumentation including a clock, and an integrated windscreen.
The enclosure panels were not new to English motorcycle design– Vincent’s “Black Prince” used a similar setup, but the Ariel had a sharper look, and offered an interesting array of colors, including red or blue offset with gray two tone paint schemes.
This bike might have done well if plans for models with larger displacement engines had come to fruition… as it stood, it won the award for 1959 “Motorcycle of the Year“.
This aspect of Ariel’s history — the potential the company might have had — fascinates many contemporary motorcycle enthusiasts like me , who find the old big-displacement Ariels appealing but unobtainable.
Ariel made their last motorcycle, a 200cc “Ariel Arrow”, in 1967.

Norton unapproachable
Like Ariel, Norton Motorcycles were also built in Birmingham.
Like Triumph, Norton Motorcycles has had several reincarnations.
Unlike most English motorcycle manufacturers though, Norton’s most popular and innovative bikes came after World War II.
The Norton pre-war story is similar to the others…
… it started making motorcycles in 1902, using French and Swiss made engines.
Norton made its own engine starting in 1908 – one cylinder, side valve, 2 hp.
In 1922, Norton developed a motorcycle nicknamed “Speedy” — a 490 OHC “Model 18“, capable of nearly 100 MPH.
Development, initially slow, sped up with the development of that first overhead cam engine.
It was perfect for the Norton “CS-1“, a TT racing-bred sled that made about 25hp with the 490cc.
Soon behind that came the “CJ-1“, with a 350cc OHC.
Starting in the 1930′s, Norton had excellent results in the motorcycle racing circuits with these bikes, winning the Isle of Man Senior TT seventeen times before 1955.
During World War II, Norton production focused on the “16-H” — a 490cc single cylinder, four-speed model of which over 100,000 were made, and designated “WD-16H” — these bikes were highly prized for their endurance and high ground clearance.
After the war, Norton continued production of the “16-H” and the “Model 18” , adding telescoping forks, adjustments to the suspension and updating the style a bit.
Norton WD-16H
Norton released it’s twin cylinder 500cc pushrod “Model 7” in 1949, although this bike is better known as the “Norton Dominator” .
The “Dominator” was designed to go head to head with Triumph’s “Speed Twin” — and set the design tone for Norton twins up until the 1970′s.
A “Dominator DeLuxe” was released as a “Model 88” two years later, but this bike was plagued with quality control issues .
1957 saw the release of a new 600cc “Dominator” on a new “Featherbed” frame- called the “Model 99“, with alloy hubs, upgraded brakes, and 31hp.
One of the real classics of this time was the Norton “Manxman 650″— a bike made specifically for the American market — a limited edition with buckhorn handlebars, painted in polychrome blue, offset with a red seat and white fringe…
This was followed in 1961 by the “Dominator 650SS” cafe style bars and dual carbs.
Norton seemed like they were on a roll .
But financially, they were not doing well.
Norton had been sold, in 1953 to Associated Motorcycles Company (AMC) , who already owned AJS and Matchless …..
In 1962, AMC closed the Norton plant in Birmingham and moved production to Woolwich, London.
They attempted to modify their vertical twin engine for a 750cc to compete in the American market, but this didn’t work out too well…. vibration on models like the “Atlas 750” became intolerable.
1967 saw the introduction of a viable 750cc Norton — the Norton “Commando” .
Despite several recurring quality control issues, this bike is still very highly regarded for it’s cutting edge frame design, raked appearance, and power to weight ratio.
One hundred years from now, this motorcycle– the Norton Commando 750– will still be rated as one of the best by riders of vintage machines.
And it’s a worthy way for the Norton Motorcycle Company to be remembered.
The 850cc Mk-I version of the “Commando” was released in 1973.. raised the horsepower a couple of horses, and cut into the gas mileage, but was the last gasp of the old Norton company, and the last Commando (Mk-III 850cc) rolled off in 1975.
One further note:
A company called Norton Motorcycles UK – based in Donnington Park ( home of the famous race course) is building three models of motorcycles called “Commando” which were designed by Simon Skinner — and using a 961cc fuel injected OHV twin– these include a cafe racer, a sport model and a full size cruiser called a “Commando SE”.
