Production of the bike, the oldest motorcycling marque in the world, is poised to rise nearly fivefold from its present level of 9,000 a year under a pounds 70m investment plan.
The expansion will increase Triumph's workforce from 250 to at least 600 and create an estimated 1,000 jobs among suppliers and service companies. In 1997, when a new factory opens next to the existing plant, output should reach 40,000 compared with 2,000 three years ago.
Even that will be a far cry from Triumph's heyday in the mid-1960s when the company, then in Coventry, was turning out 80,000 a year. In the 1960s it was absorbed into Norton Villiers but was unable to withstand the onslaught of the Japanese. Although it was resurrected in 1974 as the Meriden co-operative, this stopped trading in 1982.
Triumph owes its revival to the property magnate, John Bloor, who rescued the marque in 1983 and then spent eight years re-engineering the bikes before their relaunch in 1991.
Mr Bloor took state-of-the-art design and married it with British wage rates and sophisticated Japanese components. About one-third of the bike is assembled from components brought in from outside Europe - mostly Japan, which supplies carburettors, suspension and electronics. But a third is British-built.
The bikes, with the original names such as Tiger, Trophy, Trident and Daytona, cost from pounds 5,000 to pounds 10,000.
Michael Lock, Triumph's sales and marketing director, said: 'The average age of our customers is 39. Generally they are professional people who had a bike 20 years ago, gave it up for a job, a mortgage and a family, and are rediscovering their youth.'
Although Britain is the biggest market for Triumphs, four in five are exported.Reuse content
