1977 Triumph Bonneville T140


Triumph is synonymous with British motorcycles, along with BSA (Birmingham Small Arms Company). Originally founded in 1885 in Coventry, England by (ironically) a German immigrant named Siegfried Bettmann, Triumph has experienced several ownership changes and spinoffs into cars and bicycles over the decades, including acquisition by BSA in 1951. Yet the Triumph motorcycle brand persists to this day.

In the US, Triumph gained popularity and publicity in 1953 when Marlon Brando rode a Triumph Thunderbird 6T in the movie The Wild One (interestingly, Triumph would eventually license the name Thunderbird to the Ford Motor Company). This exposure helped propel Triumph to eventually become the best-selling European motorcycle in the United States in 1978.

Our featured motorcycle is a 1977 Bonneville T140 from Triumph’s zenith era with some tasteful modifications and enhancements to make this a compelling offering. It is a well-executed cafe build by Jay Strait of Brit-Tech and includes a custom hand-made chrome Manx-style tank, side covers, leather-covered seat with alloy pan, and reliable kick start and electronic ignition. The engine was recently rebuilt five years ago and is ready to offer years of enjoyment for its new owner. Check it out on Ebay with a buy-it-now price of $15,500. Grab a cool-looking slice of British history before it is too late.

For your consideration is my 1977 Bonnevile Cafe’. I had this built about 15 years ago by the well known Triumph enthusiast Jay Strait of Brit-Tech. 5 years ago I had the bike’s motor totall rebuilt by Ave Tenkarian from Rhode Island. IMHO “Ave” is THE vintage person. When Ave works on a bike it’s done right. Very dependable. This machine can sit thru the winter and will start 1st or 2nd Kick w/ electronic ignition. Alloy bits (Tank, side covers and leather seat w/ alloy pan) were handmade by Evan Wilcox. I had to send the frame to him to to fit the one-off  hand made Manx style tank. The Tach is a VERY cool deal! From a Vincent Black Shadow. Started as a Speedometer and was made into a Chronometric Tach and the face was screened Triumph. That work was done by KTT services in Australia and has been working perfectly for 15 years. That Tach alone set me back $3,600 in 1998! Vincent plate frame and “STOP” light. Ace bars w/ hard to find “Gummy ” grips.  Norman Hyde rear sets, ACE rubber mounted bars, swept back pipes w/ pea shooters and vintage fluted glass 9″ light. Just a ball to ride!! Approx 7K miles since rebuild. This is no trailer queen. This machine represents a carefully ridden patina and creates a crowd. All others are gust pretenders to the throne ; ) Happy to answer questions..Thanks for looking.
