1965 Triumph Bonneville 650

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1965 Triumph Bonneville 650 is a matching-numbers example with 2700 miles on a 2014 nut-and-bolt refurbishment. New paintwork and cosmetic updates have been carried out, as well as a mechanical freshening that included a rebuild of the 650cc parallel twin and four-speed transmission. The seller reports that the bike has performed well over the two years since the overhaul, and it is described as a fully sorted example which is ready to enjoyed or displayed. Its condition is detailed in the photos and walkaround video below. The sale includes a clear Kansas title.


Originally finished in a blue and silver color scheme, the restored original sheet metal is now painted in two-stage black and English Cream set off by copper pinstripes. The finish retains a deep gloss on the tanks, covers, and fenders thanks to climate-controlled indoor storage. Minor flaws are reportedly limited to a chip in the frame’s steering neck along with a small touch-up on the underside of the tank as shown in the gallery.


Fasteners were removed and reconditioned as necessary, while the tubular frame was cleaned and recoated. Satin-finish metalwork looks smooth and even throughout, and the chrome shines well on the stock badging and tank-mounted “parcel grid.” Union Jack flags on the rear shocks are complemented by other stock and period decals. The headlight wears an aftermarket mesh guard, and a single mirror is fitted on the left handlebar.


Smiths gauges feature an instructional warning decal and an odometer that was zeroed at the time of restoration. Controls appear in order, and accessories are said to work as they should. The seat was reupholstered in the factory style to match the two-tone paintwork, and shows slight piping distortion but no signs of damage or wear. Rubber grips, knee pads, pegs, and bellows look fresh and show little wear.


Rated at 46 horsepower when new, the numbers-matching 650cc parallel-twin and four-speed transmission have been rebuilt and cosmetically refreshed as necessary. The motor is said to start on the first kick and run well since its overhaul. The bike has no current mechanical needs according to the seller.

Stock Amal carburetors have been tuned to provide the smooth idle demonstrated in the walkaround video above, which also reveals a throaty rumble through new dual exhausts showing minimal heat staining.


The engine stamp shown above matches number 16650 stamped on the frame tubing. A stamp for type T120SR is also present, with the “SR” thought by many in the vintage Triumph community to indicate a US-market “Sports Road” model.


The front suspension forks were rebuilt, and the drum brakes, rear shocks, and tires are described as being in fresh condition. The bike ride is said to ride and handle well at highway speeds or on twisty back roads.


The “Bonnie” is pictured above before its refurbishment with ape-hangers, turn signals, side bags, and other modern updates that have now been eliminated. Additional photos of the work performed are included, along with some past records and parts receipts.
