1969 Triumph TR6
1969 TRIUMPH TR6 BY THE NUMBERS For the first time ever, a Triumph TR6 was called a “Tiger”. In fact the entire 1969 Triumph TR6 model lineup were all Triumph Tigers & would remain so for the rest of its life. Interestingly however, Triumph workers at the Meriden factory continued to refer to the TR6 …

1977 Triumph Bonneville
ABOVE & BELOW: 1977 Triumph Bonneville T140V was essentially carried over from ’76, as would be the practice from now on. Budget constraints were choking the company and it’s products. This one is in the Polychromatic Blue and Cold White paint scheme. FOCUSING ON ONE MODEL As the 1977 model year opened, the Meriden Co-op …
1974 Triumph Bonneville
SHORT MODEL YEAR The 1974 Triumph Bonneville was built in very low numbers. It was a very odd year in Triumph Bonneville history. Angry workers hearing of the impending shutdown of the Triumph Motorcycles plant at Meriden, shut it down themselves in protest, in October 1973 just as production was being switched from 1973 models …
1976 Triumph Bonneville
ABOVE: The 1976 Triumph Bonneville is the first to adopt left-side shift. Note shifter coming out of primary case. SPANISH AMALS? Engine mods were few. A new muffler set were now almost cylindrical reverse-cones (very little taper) & noise reduction revisions. The twin 30mm Amal Concentric carburetors were now being produced by the company’s Spanish …
1969 Norton Commando
1969 Norton Commando Fastback ABOVE: 1969 Norton Commando Fastback MODEL DESIGNATIONS The 1969 Norton Commando came in one additional model for 1969, its second model year in production. The 1968 Norton Commando was available in one model only, and so was simply called ‘Norton Commando’, even though it had what was to become known as …
1960 Triumph Twenty-One
1960 TRIUMPH TWENTY-ONE HAS BATHTUB STYLING. The British home market had been hungry for cheap transportation after WWII, and commuter motorcycles helped fill that role. But England being…well, England, was wet and rainy and to prevent rust an owner needed to wipe his bike down each night after getting home from work. This was a …
1938 Triumph Speed Twin
INTRODUCING THE 1938 TRIUMPH SPEED TWIN It’s hard to overstate the significance of the introduction of this bike. Until the moment of its launch, just about every British motorcycle manufacturer was producing mostly big air cooled pushrod singles, but as displacement and performance grew, so did engine vibration. They’d reached the single’s practical limits at …
Norton Dominator
CROWDED MARKET The Norton Dominator was Norton’s entry into the crowded vertical twin market, & it was intended to capitalize on the success of, & hopefully steal some sales from, the trend-setting Triumph Speed Twin. When it was introduced in 1949, the 500cc Dominator Model 7 was a handsome enough machine. The new engine was …
1947 Triumph 3T Deluxe
1947 TRIUMPH 3T DELUXE BACKGROUND Triumph production reverted to civilian machines in 1946, following the end of World War II. The biggest market that the British motorcycle industry needed to fill was the pressing need for cheap, economical transport to-and-from-work. In response, Triumph announced the new 3T, a 350cc companion to Edward Turner’s 500cc 5T …

1946 Triumph 3T
1946 TRIUMPH 3T BACKGROUND As Triumph production reverted to civilian machines immediately after the end of World War II, the company announced the new 3T, a 350cc companion to Edward Turner’s 500cc 5T Speed Twin. The 3T was similar in many respects to the Speed Twin, but also borrowed features from the TRW and 3TW …
Les Harris Bonnevilles
Les Harris Bonnevilles Rise from the Ashes The story of the Les Harris Bonnevilles is one of the more fascinating in all of Classic British Motorcycles lore. Such was the reputation of the Triumph name & the enthusiasm & optimism of its most devoted followers that after the 1983 collapse of the Meriden Co-operative-owned Triumph …
Norton Atlas
EVOLUTION OF THE ATLAS The Norton Atlas evolved from the Norton Dominator line, which had grown since its inception in 1949 from 500 cc to 600cc then again to 650cc with the fire-breathing twin-carb Dominator 650SS. The Norton Atlas was the next logical step. The venerable Bert Hopwood-designed vertical twin that had started out life …
1961 Triumph Twenty One
1961 TRIUMPH TWENTY ONE HAS BATHTUB STYLING. The British home market had been hungry for cheap transportation after WWII, and commuter motorcycles helped fill that role. But England being…well, England, was wet and rainy and to prevent rust an owner needed to wipe his bike down each night after getting home from work. This was …
Triumph Twenty One
THE TRIUMPH TWENTY ONE MISSION There are two schools of thought on the name ‘Triumph Twenty One’. It’s either honoring the 21st anniversary of Triumph Engineering, or was derived from the bike’s displacement in cubic inches. Either way, that was just it’s name. It’s model designation was 3TA, and it was Triumph’s entry-level 350 twin. …
1959 AJS Model 31
1959 AJS MODEL 31 BACKGROUND AJS and sister-brand Matchless were late to the vertical twin party. Triumph started it all with the 1938 Speed Twin, the world’s first ‘modern’ vertical twin (aka: parallel twin). It took the world by storm, and suddenly every other British brand had to have one of their own. Alas, World …
Royal Enfield Interceptor
ROYAL ENFIELD INTERCEPTOR BACKGROUND Royal Enfield hopped up its 692cc Constellation and created a new model, the 700 Interceptor in 1960, for sale in the US and Canada markets only (on England). They’d just lost their contract to rebadge Constellations with Indian Motorcycle regalia then selling them in the US (or trying) as the Indian …
1979 Triumph T140D Bonneville Special
MY 1979 TRIUMPH T140D BONNEVILLE SPECIAL I own a ’79 T140D myself. It’s pictured above, on display at the Quail Motorcycle Gathering in Carmel CA in 2011. The day after this show I rode it in the Quail Ride, which took us through the hills around Carmel. It happened to be my birthday, and what …
Triumph TR6
Sweet 1970 Triumph TR6 Trophy, with high pipes (on the other side). THE ORIGINS OF THE TR6 The story of the Triumph TR6 starts, as does virtually every British vertical twin, with the seminal 1938 Triumph Speed Twin. This 500cc cast iron twin started it all & after WWII when civilian production was resumed, it …
1961 AJS Model 31
1961 AJS MODEL 31 BACKGROUND AJS and sister-brand Matchless were late to the vertical twin party. Triumph started it all with the 1938 Speed Twin, the world’s first ‘modern’ vertical twin (aka: parallel twin). It took the world by storm, and suddenly every other British brand had to have one of their own. Alas, World …
Hinkley Triumph Motorcycles
Hinkley Triumph Motorcycles Hinkley Triumph Motorcycles have a rich and interesting history, despite being a fairly young company. The classic Triumph brand led the performance motorcycle market from the end of World War 2 until the late 1960s, when the Japanese absolutely conquered the market. Almost the entire British motorcycle industry collapsed before a relentless …
Velocette LE
THE VELOCETTE LE – A BEST-SELLER? Immediately following World War 2, there was a pressing need in the UK for simple, inexpensive, utilitarian personal transport to get to-and-from work. Velocette attempted to tap into this market with their radical new “LE” in 1948. LE stands for “Little Engine”, and it certainly was. The 149cc water-cooled, …
Norton Navigator
NORTON NAVIGATOR BACKGROUND Norton has always been known for big powerful bikes like the Manx and the Commando. But they also had a very ambitious line of smaller bikes that they originally built to respond to a change in British motoring law that was announced in 1958. Starting in 1960, first-time British motorcycle riders would …
1977 Triumph Bonneville Sliver Jubilee
1977 Triumph Bonneville Silver Jubilee US-Market Version ABOVE & BELOW: The US-spec version of the 1977 Triumph Bonneville Silver Jubilee had a typical US-style teardrop tank. (Pictures courtesy of MidAmerica Auctions.) CELEBRATING A QUEEN Elizabeth II was crowned Queen of England in 1952. 1977 was the 25th, or Silver Anniversary of her coronation and the …
1970 Triumph Bonneville
BEST EVER The 1970 Triumph Bonneville T120 was not only the high water mark in Triumph 650 development, and the year that most people favor as ‘the best Triumph Bonneville ever built’, it was also the last year before the dreaded Oil-in-Frame bikes arrived, and all the problems with cash-strapped owner BSA began to …
1961 Triumph Bonneville
NEW MODEL DESIGNATIONS Starting with the 1961 Triumph Bonneville, the T120 model designation was followed by either an “R” for Road models with low pipes, or a “C” for the Street Scrambler with high pipes. Changes in the new bike were minimal, yet the steady process of development and improvement never abated. Of course, again …
1965 Triumph Bonneville
SLOW STEADY REFINEMENT The 1965 Triumph Bonneville T120 650 was again more or less a carry-over from 1964, which itself was a carry-over from 1963. Changes were minor and evolutionary in nature, aimed at refinement, improving reliability, performance and ease of production. Model designations were also carryovers: T120R was the road machine with down pipes; …
1980 Triumph Bonneville
ABOVE: 1980 Triumph Bonneville T140E in Steel Gray & Black. SLOW SALES HURT CO-OP By 1980, what was left of the “Triumph magic” had evaporated. Large numbers of 1979 Triumph motorcycles were still sitting unsold in dealer showrooms & factory warehouses. For the first time since the end of WWII, the home market (Britain) was …
1978 Triumph Bonneville
ABOVE & BELOW: This 1978 Triumph Bonneville is a T140V, which still has the Delta-style head with splayed intake ports & Amal Concentrics. Later 1978 Bonnevilles were T140E’s, with parallel intake ports & MkII carbs. This color scheme was popular in 1978. A sign of the times: earthtones were in, even for motorcycles seats. SMOG …
1971 Triumph Bonneville
ABOVE: This 1971 Triumph Bonneville was restored to ‘better-than-new’ condition. It won “Best of Show” Award at the Clubman’s All-British Weekend 2011 motorcycle show. TOTALLY NEW, BUT BETTER? The 1971 Triumph Bonneville was a totally new bike. Only the engine carried over from 1970. Not since the 650 twin went unit construction in 1963 had …
1959 Triumph Bonneville
ABOVE: The 1959 Triumph Bonneville had the big fenders and nacelle of the Triumph Thunderbird. Not a popular move with Americans, many of whom swapped it out for the more svelte TR6 bodywork. ALL NEW BIKE When it was introduced, the 1959 Triumph Bonneville 650 was one of, if not THE fastest motorcycles you could …
1962 Triumph Bonneville
1962 TRIUMPH BONNEVILLE -MODEL DESIGNATIONS The 1962 Triumph Bonneville again came in two basic model designations: T120R was the Road version, and T120C was the Street Scrambler/Off-Road version (what later might have been called an Enduro). Most of the bike was strictly carry-over from 1961. Of course, this was the last year for the non-unit …
1966 Triumph Bonneville
MORE POWER, SCOTTY! By the release of the new 1966 Triumph Bonneville T120 650, Meriden had had a few years to sort out the teething problems of the new frame and unit-construction engine, introduced in 1963. Most of the changes up to this point had been incremental, but now the real work was starting: how …
1975 Triumph Bonneville
ABOVE: This 1975 Triumph Bonneville is rarer than you might think. While it looks very similar to the 1973 & 74, very few were made due to the workers strike. MERIDIAN CO-OP FORMS The ’75 Bonneville is practically non-existent. So few were produced that it hardly counts as a model year. The Meriden factory workers’ …
1969 Triumph Bonneville
COMPETITION FROM ABROAD The 1969 Triumph Bonneville had its work cut out for it. It seemed like the Triumph Bonneville was getting faster every year, and good thing too, with new arrivals from Japan like the 1969 Honda 750/Four & the Kawasaki 500 triple. The merry men at Meriden found a few more horses hiding …
1981 Triumph Bonneville
ABOVE: The 1981 T140ES Executive was a factory touring bike, with sport fairing & saddle bags (panniers). MORE SPECIAL MODELS The 1981 Triumph Bonneville attempted to address dwindling sales with what had become “Limited Edition”-madness. Not that it was a bad thing, they turned out some pretty nice bikes. But, the problems Triumph was facing …
1979 Triumph Bonneville
ABOVE: 1979 Triumph Bonneville in T140D Bonneville Special guise, with Dark Blue & Silver paint scheme. SPECIAL EDITIONS HELP SALES Triumph motorcycles’ new owners, the employees, known as the Meriden Co-operative, or the Co-op for short, had hit on a new idea almost by accident: a limited edition special. 1978 had been the 25th anniversary …
2009 Triumph Bonneville Thruxton
2009 TRIUMPH BONNEVILLE THRUXTON BACKGROUND The 2009 Triumph Bonneville Thruxton has a rich heritage. The classic Triumph Bonneville 1959-1983 was easily Triumph’s biggest name, then and now. After the death of the old Triumph (by this time the worker-owned Meriden Co-Op) in 1983, British developer-billionaire John Bloor bought the brand out of receivership with plans …
