With origins dating back to 1902, Triumph established a long and proud tradition of building powerful and rapid motorcycles.  It wasn’t until the Thirties that Triumph, under new ownership, began to build a series of truly successful machines, beginning with the Tiger range of singles and moving on to the Speed Twins in 1937.  The Bonneville, launched at the 1958 Earls Court Motor Show, was a development of the Tiger and featured a twin carburettor 650cc engine housed in a single downtube frame.  Named after the famed Bonneville Salt Flats where Johnny Allen set records aboard the famous “Texas Cigar” streamliner earlier in the Fifties, the Bonnie established itself as the fastest production motorcycle of the era and went on to become an all-time classic.  Addressing the controversial styling of the original T120, Triumph came up with an entirely new look for 1960, starting with a redesigned “duplex” frame with twin front downtubes, a new QD headlamp and slimmer mudguards, along with various mechanical improvements including an AC alternator in place of the old DC dynamo.  Fewer changes were made in 1961, mostly confined to strengthening the frame and changing the rear wheel and tyre size, along with a new Sky Blue and Silver Sheen.  The Bonnie remained the most powerful, fastest and desirable bike in Triumph’s catalogue for over a decade, with numerous variants offered for sale along the way.  Sadly, inroads by the Japanese, along with the general complacency of the British motorcycle industry, saw the formation of the Norton-Villiers-Triumph conglomeration that year.  Such were the protests against shifting production from Meriden to the BSA factory in Birmingham that a co-operative was established in March 1975 to resume manufacture of the Bonneville at the traditional home of Triumph.  This, too, ultimately proved futile and the doors closed at Meriden for the final time in 1983, ending a proud chapter in British motorcycling history.  


  • Desirable Pre-Unit Triumph T120R Bonneville
  • Fully restored to a high standard
  • Part of a Bonnie collection
Fully restored by a specialist workshop in Melbourne several years ago, this early Pre-Unit Triumph T120R Bonneville dates from early 1961 and is beautifully presented in the correct Sky Blue over Silver Sheen colour combination.  With the mileage reset to zero at the time of restoration and corresponding engine and frame numbers, the bike is showing just 285 miles on the clock at the time of cataloguing and was recently serviced in preparation for sale.  Part of a collection of Bonnies lovingly assembled by our vendor over several years, this classic T120 will be sold unregistered and will make a wonderful addition to any Triumph or classic British bike collection. 
Note: Shannons advise that all potential buyers research and inspect motorcycles before purchase to authenticate originality and condition as a pre-purchase inspection report is not carried out on these vehicles.
