Triumph Motorcycles has sold more than 50,000 bikes in a year for the first time since the brand's rebirth three decades ago.
The Hinckley company, bought out of liquidation in 1983 by builder John Bloor, shifted 52,089 bikes in its last financial year, up from 48,957 in the previous 12 months.
The 111-year-old marque also made a record turnover of £368 million for the year to June 30, up 7.6 per cent on the previous 12 months.
However, Triumph made a £95,000 operating loss in the same period, down from a £15 million operating profit.
Bosses blamed the deficit on foreign currency changes and the cost of setting up major operations in India and Brazil.
They said sales from the firm's three Thailand factories totalled £225.5 million, accounting for 61 per cent of Triumph's overall turnover. It was previously 54 per cent.
The proportion of bikes sold outside the UK rose from 84.9 per cent to 85.8 per cent.
The company retained its title as the UK's leading big bike manufacturer.
The marque sells 24 models, including the Bonneville and Street Triple.
A Triumph spokesman said the operating loss was in line with expectations.
"Triumph Motorcycles has achieved a record turnover, reflecting a rise in unit sales," he said. "During the 12 months to November, the company's global share of the 500cc and above market has increased to 6 per cent from 5.7 per cent.
"In the UK, Triumph has continued to maintain its market position as the UK's top seller of motorcycles in the 500cc and above market in 2013, retaining a 20 per cent market share.
"The marque has also captured a 3.4 per cent share in Brazil in its first year trading in the 500cc and above market."
Triumph's latest financial figures were revealed in documents filed with Companies' House by Bloor Holdings, of Measham, which owns both Triumph and house-builder Bloor Homes.
The house-building business made an operating profit of £38 million for the year to June 30, up 19 per cent.
Turnover was £378 million, up from £373 million.
A 5 per cent rise in house prices helped offset a 5.1 per cent fall in the number of houses built, which totalled 1,908.
Triumph opened an assembly plant in Brazil this year and has just opened a plant in Manesar, in the north Indian state of Haryana.
The motorcycle maker, founded in Coventry in the late 19th century, plans to enter more emerging markets, including China and Indonesia.
