Walking Up To A Little Piece Of Germany Let me start off this review by first thanking BMW Motorrad Canada and BlackFoot Motorsports of Calgary for having the cross-Canada demo days event. For Calgary, it happened on September 3, 2021, with the first ride going at 9:30 AM on a fairly chilly day so as …

1969 BSA A65 1969 BSA A65 Lightning 1969 BSA A65 LIGHTNING The 650 Lightning was BSA’s top-line bike, and meant to do battle with the market-dominating Triumph Bonneville and had twin carbs just like the Bonnie. The ’69 Lightning was certainly fast enough and handled well. It just never had the styling to compete with …

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 …

1961 MATCHLESS G80 TYPHOON BACKGROUND Parent-company AMC knew how to build big singles. Despite now having a nice lineup of vertical twins, the real money was made selling Matchless and AJS singles. For Matchless, the top of the heap was the 500cc G80, and the best of those was the Typhoon. The AJS version was …

The 1945 BSA M20 was the last year of production during World War 2 and and just a part of BSA’s massive wartime contribution to Britain’s war effort. 1937 was its first year of production that would last until the late 1950s. Designed to be simple, rugged and reliable, the WM20 was a side-valve (flathead) …

1970 Triumph Daytona 500 1970 TRIUMPH DAYTONA – WHAT’S IN A NAME? Triumph derived the name of this bike from Buddy Elmore’s win at the 1966 Daytona 200 at Daytona Beach FL riding a Triumph T100T Tiger 500 twin. It was Triumph’s first-ever Daytona victory, with an average speed of 96.6 mph. By 1967, it …

I’m 52 years old, and I’ve been riding since I was 16. I bought the Triumph Bonneville Special brand new in 1979 at Brooks Cyclery, in San Jose, CA. It has just a little over 24,000 original miles. It’s 99% original. I had to change the fuel petcocks because the originals were made of teflon …

This 1968 Rickman-BSA 441 represents years of development. After years of racing motocross in the 1950s in England and Europe, brothers Don and Derek Rickman decided to design their own frame. At the time, most dirt bikes were simply stripped-down street bikes, which were too heavy and not ideal for racing in the dirt. They …

ROYAL ENFIELD BULLET BACKGROUND Royal Enfield had been building sturdy, reliable motorcycles since the turn of the century. They produced military motorcycles for the British army in both world wars. They struggled at the edge of insolvency throughout most of the 1930s but managed to hang on until the the second world war boosted their …

1939 Triumph T100 1939 TRIUMPH T100 – THE LAST PRE-WAR TIGER The Tiger T100 was launched in 1938. Performance was boosted by the use of high-compression forged pistons and polished ports and internals, the result being a machine that could touch 100mph in road trim and exceed it with the silencer end-caps removed. The 1939 …

1960 Triumph Thunderbird The 1960 Triumph Thunderbird was similar in appearance to this 1960 Triumph T110 Tiger. Both had ‘bathtub’ bodywork, full fenders and the trademark headlight nacelle. But the Tiger was the higher-performance version, with bigger carb, higher compression & wilder cams. Note that this bike has a 1968-70 TLS from brake. 1960 TRIUMPH …

1950 Triumph Thunderbird 1950 TRIUMPH THUNDERBIRD – BIRTH OF THE THUNDERBIRD The 1950 Triumph Thunderbird was not only the first Thunderbird, it was the first Triumph 650 & it began a long legacy that lasted until the demise of Triumph Motorcycles in 1983. It is said that Edward Turner got the idea for the name …

1952 BSA A7 Pre-Unit 500 Twin 1952 BSA A7 BACKGROUND Like everyone else in the British motorcycle industry, BSA was caught flat-footed when Triumph introduced its game-changing 500 Speed Twin in 1938. And like virtually everyone else, BSA was relying heavily on single-cylinder designs for its bread and butter. But the new twins had arrived …

1958 Triumph T110 Tiger 1958 TRIUMPH T110 TIGER – WHAT’S IN A NAME? Triumph’s naming convention followed a couple paths. But the one the Tiger was on always starts with a “T” for Triumph, then the next set of digits were supposed to reflect the bike’s top speed. The first in the Tiger lineup was …

1964 Velocette Venom 1964 VELOCETTE VENOM BACKGROUND By the time Venom production began in 1965, Velocette was almost at the end of its long road of singles. And it represented everything that Velo had learned about building a big single. They were fast, light, handled well, and were very reliable. Since Velocette never made a …

1969 Triumph Trident T150 1969 TRIUMPH TRIDENT: BRITAIN’S SUPERBIKE! At a time when Honda started building 50,000 750s a year, Triumph & BSA launched their star-crossed twins…er, triples, the BSA Rocket 3 and the Triumph Trident which combined would struggle to produce 5,000 in a good year. They were expensive to make, hard to build, …

1969 BSA Rocket 3 1969 BSA ROCKET 3 BREAKS NEW GROUND The irony here is that the mad scientists in the back room at sister-brand Triumph had 3-cylinder prototypes running around since 1965, a full 4 years ahead of Honda. But parent-company BSA dithered. It wasn’t until word leaked out of the mighty 4-cylinder from …

1970 Triumph Trident T150 1970 TRIUMPH TRIDENT – A NEW LOOK After the horrible styling experiment of the 1969 Triumph Trident in it’s introductory year, Triumph wisely decided to bring its big 750 Triple in line with the look people had come to expect from a Triumph, as typified by the Bonneville. Gone were the …

1972 Triumph Trident T150 1972 TRIUMPH TRIDENT BACKGROUND The Trident benefitted majorly from the 1971-and-later redux of the Oil-in-Frame 650 twins. While the Trident didn’t get the oil-bearing frame, it got just about everything else. Most notably, these included the new front forks sans rubber ‘gators’, the new headlight, turn signals and gauge package, the …

1975 Triumph Trident T160 1975 TRIUMPH TRIDENT AIMS HIGH It’s amazing to think about how much of a leap the ’75 T160 Trident was over the ’74 T150, especially considering that the newly-formed, worker-owned Meriden Co-op was also woefully underfunded. In other words, they had almost no money for R&D. And yet they produced this …

1970 Rickman-Triumph 1970 Rickman-Triumph Background This 1970 Rickman-Triumph is typical of many of the Rickman desert racers of the era, and represents years of development of an excellent design. After years of racing motocross in the 1950s in England and Europe, brothers Don and Derek Rickman decided to design their own frame. At the time, …

1962 Norton Navigator 1962 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 …

1955 BSA A7 Pre-Unit 500 Twin 1955 BSA A7 BACKGROUND The 500cc A7 was BSA’s first vertical twin and marked its entry into that very lucrative market, started by the Triumph Speed Twin just prior to the war. At war’s end, virtually every British motorcycle manufacturer fielded their own vertical twin, usually starting out at …

1963 Triumph Thunderbird 1963 TRIUMPH THUNDERBIRD GOES UNIT CONSTRUCTION Along with the rest of the Triumph 650 line, the 1963 6T Thunderbird converted over to Triumph’s incredible new unit-construction powerplant, frame and cycle gear. It was a major transition, with nearly every component replaced. But what a change! Unit Construction incorporated the engine, the primary …

1953 BSA Gold Star 1953 BSA GOLD STAR BACKGROUND Throughout the 1930s, BSA created and developed a strong line of single-cylinder motorcycles. In 1937, they introduced the 500cc Empire Star. When Wal Handley lapped the Brooklands racetrack at over 100 mph average speed, he was awarded a Gold Star. The name stuck and was applied …

1951 Triumph Speed Twin 1951 TRIUMPH SPEED TWIN BACKGROUND The Triumph Speed Twin was the world’s first ‘modern’ vertical twin, when it was introduced in 1937 as a 1938 model. Designed by Edward Turner (who also designed the Ariel Square Four), the 500cc 5T Speed Twin was a revelation at the time. Pretty much everyone …

1969 Velocette Venom 1969 VELOCETTE VENOM By 1969, Velocette was a year from closing its doors. Whether they knew that in 1969 or not is questionable, but surely they realized they were in dire straights, financially. Velocette was the one British brand still building bikes in the 1960s that never fielded a vertical twin. The …

2007 Royal Enfield Bullet 2007 ROYAL ENFIELD BULLET BACKGROUND Like all modern, Indian-built Royal Enfields, the 500 Bullet is a descendant of the original British-built Enfields of the late 1940s. Despite being completely redesigned in modern times by parent company Madras Motors, and sprouting modern features like electric starters and electronic fuel injection, Royal Enfields …

1946 Velocette KSS 1946 VELOCETTE KSS BACKGROUND The Velocette KSS debuted in 1925 as an OHC (overhead cam) 350cc air-cooled single. Being OHC placed it at the cutting edge of engine technology at a time when most machines still used side-valve designs or pushrods. The name KSS breaks down to the K for overhead cam …

2010 Triumph Bonneville 2010 TRIUMPH BONNEVILLE BACKGROUND Of course, the original Triumph Bonneville was introduced to the world in 1959, and had a good run until the old Triumph company went belly-up in 1983. The name was revived by British billionaire-developer John Bloor, who reintroduced a new line of thoroughly modern Triumphs starting in 1990. …

1955 Triumph Thunderbird ABOVE: The 1955 Triumph Thunderbird 6T is very similar to this 1956 Triumph Thunderbird. They share essentially the same frame, suspension, cycle gear and body work. Only paint colors & minor trim differences vary in the general appearance. Although many mechanical changes were made on an ongoing basis on all Triumph Motorcycles, …

1959 Velocette Venom 1959 VELOCETTE VENOM BACKGROUND The Venom was Velocette’s hottest bike from its inception in 1955. In 1961 a factory-prepared Venom with a small fairing set the world’s 24-hour endurance speed record of 100.05 MPH at the Montlhery race track in France. The record stood until 2008 for 500cc motorcycles. The 499cc Venom …

1973 Triumph Trident 1973 Triumph Trident T150V THE 1973 TRIUMPH TRIDENT IS A TURNING POINT 1973 was a very important year for Triumph, and in particular for its star player, the Bonneville. Because that year, the legendary 650 “Bonnie” got punched out to a 750, got a much-need and long-overdue 5-speed gearbox, and a front …

1973 Rickman 250MX 1973 Rickman 250MX Background This 1973 Rickman 250MX is the product of years of development.

They began building racing frames in 1959, and created a line of frames that were designed to accept almost any engine …

1953 Triumph TR5 Trophy 1953 TRIUMPH TR5 TROPHY BACKGROUND The Triumph TR5 Trophy was produced from 1949 through 1958. It was based on the 500cc 5T Speed Twin, but modified for off-road use. The TR5 Trophy was originally intended as a trials bike, with high side-exhaust, high ground clearance and excellent handling (for the day). …

1958 Ariel Cyclone 650 OHV Vertical Twin 1958 ARIEL CYCLONE A VERY RARE BIRD Ariel was early to the vertical twin party started by Triumph with the 1938 500cc Speed Twin. Their first entry was the model KH 500cc parallel twin launched in the first year of civilian production following World War 2, 1945. The …

1968 BSA A65 1968 BSA A65 Spitfire Royal Star ABOVE: Starting with the 1968 BSA A65, the Spitfire Royal Star joined the lineup, as BSA’s premium offering, at least until the arrival of the Rocket 3 a year later. 1968 BSA A65 Firebird Scrambler BSA’S DESERT SLED The A65 Firebird Scrambler was intended as a …
