TRIUMPH

1979 BONNEVILLE T140E SPORTS


SOLD

THE STORY

Launched in 1973, the T140 picked up where the 650cc T120 Bonneville left off with a new 750cc twin engine designed to satisfy the American market's demand for more horse power.

These new machines were all 5-speed with a front disc brake, rear drum and had oil-in-frame chassis first seen in the 650cc T120. The engines are air cooled, parallel twins.

The frames were hand welded and the tanks were hand striped.

In 1976, a rear disc brake arrived. In 1978, the bike developed a new, parallel-port cylinder head to replace the earlier splayed-head that had been a feature since 1959.

That same year, new carburettors were introduced for the T140 (Amal Mk2s) and overall, the bikes were looking more angular and modern.

THE BIKE

This Bonneville T140E sport has its original 750cc engine and has been purpose built to capture the essence of the great English café racer.

A café racer is a lightweight, powerful motorcycle optimised for speed and handling rather than comfort and for quick rides over short distances. They generally exhibit bodywork and control layout similar to 1960s Grand Prix road racing motorcycles including visual minimalism, low-mounted handlebars, prominent seat cowling and an elongated fuel tank.

They were a staple of London motorbike culture in the early 1960s where they were used for short quick rides between cafes.

The engine and frame are original and numbers matching.

New features include the custom café racer seat, brakes with stainless steel cylinders, ventail accelerator cables and upgraded front suspension forks and hoses.

The engine’s top end has been rebuilt with a T140V head and reconditioned carbs with ticklers have been added to create the side angled vintage look.

This bike has an aggressive stance, tasteful sporting finishes, is lightweight, powerful and has been optimised for speed and handling.

Original parts also come with this beauty.

Ready to ride anywhere.
