Description

A bike whose name precedes itself, the Triumph Bonneville has a storied history in racing and vintage showmanship. This bike had a target market in mind, as described by Hagerty: “the Bonneville was a motorcycle for men…. every detail [was] carefully planned by men who ride — and ride hard.”

The T140 was the second generation Bonny. It built upon the T120 with quality upgrades such as, 100 more cubic centimeters of displacement, a front disc brake, and an additional gear in the transmission. The 49 horsepower twin was good for a top speed of approximately 110 miles per hour, and the curb weight was about 420 pounds.

This example is VIN: T140ENA13932. Engine: T140ENA13932. The seller purchased the bike five years ago from a private party and states, “I wanted a Triumph that was upgraded to a more reliable, rideable bike. So, I replaced the ignition and the carbs. Big improvement. Then the hydraulic clutch. To make it pretty and a little different, I re-laced the wheels with aluminum rims, rubber fork tubes on the sliders. Rides and runs very well.”

True mileage unknown. Per the seller, “Actually less than 1,000 since total rebuild”
