What are Lairgate Motors and what types of motorcycles do they manufacture?

Lairgate Motors was a prominent UK manufacturer of motorcycles and other vehicles during the mid-20th century. They were particularly known for producing the famous 650cc twin-cylinder bike. The company's production spanned several decades, with their motorcycles gaining popularity for their performance and reliability. However, Lairgate Motors ceased operations in the late 1970s, making it unlikely that they have a direct connection to modern vehicle testing procedures or MOT inspections. Despite their closure, Lairgate Motors' legacy continues to be remembered by enthusiasts of classic British motorcycles.
