1979 Triumph T140D Bonneville Special,All Original Preservation Machine,16,030 Original Miles from NewEngine Number: T140DBA1820Frame Number: T140DBA18120
In 1979, Triumph, desperate for U.S. sales, introduced the custom inspired T140D Bonneville Special. Unfortunately, it wasn’t as custom or as special as Triumph’s ads might have tried to suggest. Something of a failure when new, it’s a rare bird today, and even old Triumph hands find themselves drawn to its unique lines.The cosmetic condition of this machine is just as it looks in the photos. Every finish on the machine is original. As far as I can tell, no part of the bike has been painted or re-finished. Please take a look at the photos in the second part ofthis description. I took as many as Icould to properly represent the motorcycle.The running condition of the machine is flawless, starting on the first or second kick.This bike has been part of my collection for a while and is ridden on a regular basis. It’s basically a well-maintained and well cared for bike that runs and rides with absolutely no issues. Leave it the way it is (preferred) or restore it eventually after having some fun with it. I just happen to like unrestored bikes.The paint on the tank, side covers, etc. are original, and have never had any type of paintwork or touchup, as far as I can tell. The paint and chrome on the frame and associated parts is also original, and aside from some minor age freckling, is in very nice condition. The bike has never been in any type of accident or been dropped at any time.The seat is also in original condition and is in beautiful condition.The Bonneville runs and rides the way you expect a machine with this type of mileage to run. All of the mechanical components have been checked over to ensure they work properly including the clutch and brakes. The fuel system was completely gone through this season and functions perfectly. The charging system also works perfectly. Although the tires currently installed are serviceable, they should be replaced if you plan to do anything but light riding and a show or two. But right now, there is absolutely nothing you will have to do to this motorcycle to ride and enjoy it this season.And pleasedon't forget to take a look at all of the photos in the description section of the ad!

Price then/now:$2,700/$4,000-$10,000The T140DDesigned to capitalize on the growing custom-styled “specials” market in the U.S., the T140D Bonneville Special featured a very attractive black and gold paint job on an American-style “slimline” gas tank, a shortened front fender, a slightly stepped seat, and cast badges. A distinctive 2-into-1 exhaust hung on the right side, and it rode on seven-spoke U.S.-made Lester mag wheels, a first for Triumph, with a fat rear tire enhancing the bike’s custom look. The engine was basically the same as found on a standard Bonneville, with the exception of threaded exhaust ports.
The Co-op soldiered on, despite worsening economic conditions that led to repeated layoffs. Although a strong British pound was increasing U.S. prices and dampening sales, changes and improvements continued. Bonnevilles finally got an electric starter in 1980, and an 8-valve head came in the middle of the 1982 model year. But in 1983, with the U.S. economy in turmoil and overall bike sales plummeting, the Co-op finally ran out of money. The rights to the Triumph name were sold to John Bloor, who later built a new factory in in Hinckley, 25 miles away from the old Meriden plant, and got Triumph going again.
