NEW BUILD: 1977 T140 Bonneville

Although not as prized as earlier models by collectors, the late model twins are some of the most road-worthy bikes that Triumph ever made. In stock trim, the 1977 T140 is equipped with front and rear disk brakes, turn signals, left side gear shift, and a five-speed transmission. The goal with this build was to retain all of the features that make the ’77 a great rider, while improving performance and streamlining the cosmetics.

The donor bike was a high-mileage example purchased from a horse trader in upstate New York. Although this is the first Amity build that began as a running machine, this did not stop us from a full motor rebuild, including new pistons/rings, a fully reconditioned head, and a new exhaust cam with the classic spitfire profile (a stronger timing side main bearing was used to handle the improved power). The clutch was fully rebuilt with a Norman Hyde seven-plate kit for no-slip, no-grind, trouble-free operation. The electrical system includes all new components, a UK-made cloth-bound wiring harness, and a Pazon electronic ignition for reliable starting and ease of maintenance. The powdercoated frame and cycle parts, freshly painted body work, and beautiful custom seat roll on new stainless wheels and Avon tires.

This motorcycle is fast and smooth and perfect for either the twisting back roads or wide open highway. All work except upholstery and head reconditioning was done in house, including paint, wheel lacing, and motor rebuild.
