The Triumph Bonneville needs no introduction, but this classic Brit was named after the Bonneville Salt Flats in Utah. Triumph was fairly successful racing this bike, with wins at the Isle of Man TT Production 750cc class coming in ’67 and ’69.

The Bonneville was produced in its original run (the T120) for 16 years, with a 650cc engine that made 46 horsepower. The parallel twin was based on the Tiger 110, but with upgraded Amal carbs that helped the bike attain 115 miles per hour stock – though Johnny Allen set a record in 1956 with a heavily modified Triumph hitting 214.17 mph over a standing mile.

Many motorcycle enthusiasts consider the late 60s models to be the ‘best’ of the classic Bonnies. Along with offering improved reliability and performance compared to the 1959 original, they also avoid the complications associated with the oil-in-frame models produced from 1971 onwards.

This example is VIN: T120RDU35328. The seller purchased the bike in 2022 from a collector and states, “Love staring at this bike, it’s super clean and beautiful and from my birth year. Its had a high level complete restoration and is without flaw that I can find. It sold for $15,400 at Mecum Vegas auction in 2015.”

True mileage unknown. During his ownership, the seller has covered approximately 30 miles. The odometer shows 385 miles since the restoration.
