Harley-Davidson 1947 model EL “ Knucklehead” 989 cc OHV V-twin engine # 47EL11283 video: https://youtu.be/i2cg_vsh9bM During the Depression years of the early Thirties Harley started the development of a new line of motorcycles, an up-to-date OHV model with sophisticated dry-sump recirculation lubrication system and a constant mesh four-speed gearbox. The frame was different of that of any other Harley: a duplex loop with twin down tubes. The new model was well-designed but hastily launched on t ...

Rudge Multi 1920 499cc IOE single frame # 769645 engine # 18785 Multi-gear # 12696 With the introduction of the Multi Gear in 1912Rudge was far ahead of the competition. They won the 1914 TT races with this system and Rudges were subsequently barred from certain speed events because of their “unfair head start”. The factory turned this to their advantage by using the “ barred” logo in a clever company advertising campaign. The Multi Gear system is based on the possibility to vary the diameters o ...

Anton Wiklund was one of the pioneers of the bicycle industry in Sweden. The factory in Stockholm was very progressive in its designs, and this is evident in this elegant and lightweight safety bicycle. This safety bicycle, in which the top tube slopes upwards only slightly, features Trelleborg 28″ pneumatic tires and a lightweight frame and handlebars made of hollow tubes. Around 1894, this bicycle was the best available on the market. Frame number 4645 is stamped under the bottom bracket and i ...

BMW 1961 R50S 494 cc transverse OHV twin frame & engine # 564463 video: https://youtu.be/mnsWk47U5Uc Bayerische Motoren-Werke is known in English as the Bavarian Motor Works, or more simply as BMW. The firm launched its first horizontally opposed twin in 1923, and has stood by this style of engine layout ever since.

Laverda 1971 750 SF 744 cc OHC twin frame # LAV750F5132DGM.5934.0M engine # 750*5132* video: https://www.youtube.com/watch?v=VpGjbWrvggs Founded in 1873, Laverda started out making farm machinery, only turning to motorcycle manufacture in the immediate aftermath of WW2. Lightweights, scooters and mopeds formed the mainstay of Laverda production up to the late 1960s when the small Italian concern, hitherto little known outside its home country, astonished the motorcycling world by introducing a 6 ...

The 1933 model year catalogue introduced the Bullet models in the 250, 350 and 500 cc class: “ The vogue of the high-efficiency sports motor cycle has produced nothing fin ...

After World War II, the company began producing utility three-whe ...

Hesketh 1982 “Vampire” 992cc 8-valve OHC V-twin frame # 055 engine # 0130 Brainchild of wealthy aristocrat and Formula 1 team owner Alexander Furmor-Hesketh, the Hesketh V1000 promised to be an all-new British superbike in the Vincent mould. The proposed design had all the right ingredients: 992cc 8-valve Weslake v-twin engine, nickel-plated Reynolds 531 frame, Brembo brakes, Marzocchi front forks, Dellorto carbs, Lucas Rita electronic ignition and Astralite wheels. In the spring of 1980 the fir ...

Velocette 1949/1950 KTT Mk VIII 348cc OHC frame # SF 231 engine # KTT1044 After the 1928 TT win Velocette marketed the KTT as the first British “over the counter” racer. Thus began the production of a competitive racing motorcycle that was very successful for almost 25 years. The final development of the Velocette KTT, the Mk VIII, was introduced in 1938 at that year’s Earls Court Show, and was the first motorcycle to use the now-conventional swinging-arm rear fork with a shock absorber unit. Th ...

Clément 1903 Type D Autocyclette 192 cc OHV frame # 105649 engine # 3633 In 1902 Adolphe Clément enters the field of motorized bicycles with a small engine of 126 cc capacity.

Harley-Davidson 1924 989 cc IOE V-twin model “FE” engine # 24FE12029 1924 is not a good year for the firm: the losses amount to almost $ 120,000 and the workforce is trimmed down from 2,500 to 1,000 employees. Sales in the USA have seriously diminished in the early twenties because of the competition of the cheap automobile. A positive thing is that export sales are still looking good. More than 6000 machines are exported oversees this year; this amounts to almost half of all Harleys manufacture ...

Matchless 1969 P11A Street Scrambler 745 cc OHV twin frame # 125913 engine # P11/125913 “Big, chunky-tyred wheels support a frame and power plant that really mean business. The tank clings leech-like to the frame and glows in Candy Apple Red. Below it run some of the most sensually curved exhaust pipes ever bent, feeding into skimpy, sawn-off barrel silencers. And the briefest of saddles offers seating at handlebars that pull back like the ears of a startled hare. The Norton P11 street scrambler ...

Harley-Davidson 1934 Model B 346 cc side valve single engine # 34B1104 In the mid-twenties the H-D management decided that, especially in the European and Australasian markets, a small-capacity HD would be a selling point, if only to act as a “starter model”. So in 1926 some 350 cc class models were brought out; the OHV versions were rather exotic machines mainly meant for competition use, but the side valve models 26A and B (the B had an electrical lighting system) were good sellers: more than ...

Excelsior 1919 Series 19 in Board track racer trim 974cc IOE V-twin frame # 20579/9 engine # 101848 1911 was a landmark year in Excelsior’s history, for the firm was acquired by bicycle maker Ignaz Schwinn and it introduced its first v-twin model that year. In 1913 the 61ci (974cc) twin was offered with all-chain drive, while two-speed planetary transmission and a leaf-sprung, Indian-style front fork were two of the following season’s innovations. Alongside rivals Harley-Davidson and Indian, Exc ...

Henderson 1929 “ KJ” 1305cc four cylinder engine # KJ31180 video: https://youtu.be/W3UX2ekR9Q0 Founded by Tom and William Henderson in Detroit in 1912, Henderson built nothing but four-cylinder motorcycles in its 19-year existence. Numerous detail improvements were made throughout the 1920s to ensure that the Henderson remained ‘the finest motorcycle in the world’. Nevertheless, by the decade’s end it had become obvious some thorough design changes would be needed to stay ahead of the pack. The ...

Henderson 1924 “DeLuxe” 1305 cc side valve four cylinder combination frame # D12108A video: https://youtu.be/0pPzYCkw4Uo Although the brothers Tom and Will Henderson had made excellent motorcycles from 1911 on, they didn’t manage to get the company financially sound. In the course of 1917 Ignaz Schwinn, who had already taken over the Excelsior Supply Company by the end of 1911, showed an interest to take over the production of the famous Henderson Four. Towards the end of the year the deal was s ...

ARIEL 1954 Model VH 497cc “Red Hunter” frame # KS1286 engine # PD104 video: https://youtu.be/mczHRcLdGV4 The basics of the “Red Hunter“ design can be traced back to a Val Page, but the name first came into use in the 1932 programme that had been designed by Edward Turner. The new sporty OHV models in 250, 350 and 500cc capacities were very good-looking, reliable and sturdy. They became great performers in off-road competition work as well as for fast touring and were further developed and produc ...

Cotton 1937 “Model 29/J” 349 cc OHV JAP two-port frame # 15114 engine # IOS F3910 /SE The Gloucester-based Cotton factory was one of many small manufacturers that used proprietary engines in the years between the first en second world wars. But there was something quite special about the Cotton, that made it much more successful than most other small makes: its frame. The frame that Frank Willoughby Cotton designed around 1914 was of triangulated construction, very light and exceptionally strong ...
