Triumph T 140 V Bonneville Silver Jubilee Classic Motorcycles for Sale

History of the Triumph T140V Bonneville Silver Jubilee

In 1977, Triumph released the T140V Bonneville Silver Jubilee to commemorate the 25th anniversary of Queen Elizabeth II’s reign. Produced by the Meridan Motorcycle Co-operative, this edition was based on the 750cc Triumph Bonneville T140V. Uniquely, the Silver Jubilee was limited to 1,000 examples for the UK, 1,000 for the US, and about 400 for other global markets. The colour scheme and detailing highlighted its British heritage and the significance of the royal occasion, creating strong recognition and collectability from the outset.

Model History

The Silver Jubilee, designated T140J, builds on the mechanical package of the T140V, itself an evolution of the earlier 650cc Bonneville twins. The Bonneville line is rooted in post-war British motorcycle success, with the T140 series launching in the early 1970s as Triumph’s response to increasing competition in the 750cc class. After the Silver Jubilee, Triumph continued experimenting with special editions, like the 1981 T140LE Royal Wedding model. Production at the Meridan works reflected Triumph’s turbulent but ambitious efforts to keep British motorcycling relevant.

Highlights

Distinctive features of the Silver Jubilee include its metallic-silver paintwork, with hand-applied red, white, and blue pinstripes referencing the Union Jack. Both the tank and side panels received specific Jubilee badging, and chromed engine covers further set the bike apart. Market-specific differences include a more angular 4.5-gallon 'square tank' with knee pads for the UK, while US models received a teardrop design. The exclusive 'King and Queen' dual seat in dark blue vinyl with red piping, Smiths instruments, and special plating on handlebars and lamp shells added to the bespoke nature. Each bike was delivered with a Certificate of Ownership, underlining its special status.

Special Editions and Collectible Models

The T140V Bonneville Silver Jubilee was itself a special limited run, marked by its 'J' suffix (T140J). In 1981, building on the positive response, Triumph launched the T140LE 'Royal Wedding Edition,' further cementing their tradition of commemorative models. The hand-finished paintwork, individually numbered certificates, and unique equipment are central reasons the Silver Jubilee stands out as the most exclusive of the T140 series.

Engine, Transmission, and Handling

The 744cc parallel-twin delivers its 54 horsepower smoothly via a well-spaced 5-speed gearbox. Twin Amal carburettors and Lucas ignition provide period-authentic fuelling and spark but require regular tuning. The steel frame with oil storage offers good structural rigidity, while the riding experience benefits from the two-way hydraulic front fork and classic Girling shocks. The braking system, single discs front and rear, demands mechanical sympathy and is most effective with properly paired Dunlop TT100 tyres. Handling is characteristically stable at touring speeds, with the square tank version offering better knee grip for UK riders, while US models deliver a slightly lighter feel from the teardrop tank. - Triumph Bonneville T140V: Base of the Silver Jubilee

Design, Materials and Equipment

Defined by its hand-painted metallic silver finish, each Silver Jubilee displays red, white, and blue pinstriping inspired by the Union Jack. Unique Jubilee badges on side covers and tank, chromed engine covers and wheel rims, as well as dark blue 'King and Queen' stepped seat with red piping set the tone. UK-market bikes carry a large squarish tank with black knee pads, US versions opt for a slender teardrop tank. The instrument cluster features period Smiths dials, with chrome-plated chokes and lamp shells. Standard fitments also include a rear grab rail, lockable steering, and dedicated 'Silver Jubilee' documentation, reflecting the premium ambitions for the special edition.

Other Noteworthy Features

Each Silver Jubilee motorcycle was delivered with its own Certificate of Ownership, underscoring both its limited production status and its purpose as a celebration of British heritage. Accessories specific to this edition, such as side-panel badges, pinstriped wheels, and blue seat with red piping, were unique at the time and remain significant distinctions.

The Triumph T140V Bonneville Silver Jubilee occupies a prominent place among British motorcycles from the late 1970s.
