Up to 50 jobs could go at the Leicestershire motorcycle maker Triumph under plans to relocate mass production to Thailand.
The company, which has a factory in Hinckley, is realigning operations under global ambitions to take a bigger chunk of the Asian market.
Triumph said that while mainstream production would move to its existing plants in Thailand, Hinckley would become its global research and development centre, leading to more than 20 new design engineer jobs.
A letter to staff said the company was consulting about job losses.
The company makes around 65,000 motorcycles a year. Up to 7,000 are produced in the UK. This could fall to around 4,500.
