This 1961 Triumph TR5A/C Trophy comes from the competition-based model’s only year of production and was sold new in Baltimore, Maryland. It remained with its previous owner from 1987 until being acquired by the seller in January 2022, and the 498cc parallel twin was overhauled with .020″-oversized pistons at that time. Features include an electronic ignition module, a right-side-shifted four-speed gearbox, a two-into-one-exhaust system, Frank’s Forks stanchions, LED lights, a two-up seat, and a Smiths Chronometric speedometer. This TR5A/C is now offered at no reserve with period literature, service and parts receipts, and a clean Colorado title in the seller’s name.
The fuel tank and fenders have been refinished in blue and silver, and the bike has been fitted with an LED headlight and taillight in addition to a replacement horn. Features include a two-up seat, both center and side stands, and black rubber knee bolsters.
The bearings in the wire-spoke wheels were cleaned and repacked, and the 19″ front and 18″ rear rims were mounted with Duro tires. Suspension consists of a conventional fork that was fitted with Frank’s Forks stanchions and replacement seals in addition to a pair of shrouded shocks mounted to the swingarm. Braking is from drums at both ends.
The replacement chrome handlebar is mounted in pullback risers that frame the adjustment knob for a steering damper. Instrumentation consists of a Smiths 123-mph speedometer that contains a five-digit odometer that shows 25k miles, approximately 100 of which were ridden by the seller. The speedometer cable has also been replaced.
The 498cc parallel twin features an Amal carburetor and a two-into-one exhaust system that exits low on the right, and it has been modified with a Pazon 12-volt electronic ignition and a hidden ignition switch. The engine was overhauled in 2022 with .020″-oversized pistons and work that included cleaning the sludge trap and replacing the gaskets, valves, journal bearing, timing-side crankcase, lower-end bushings and bearings, wiring harness, and rectifier. The seller notes that the carburetor is set for an 8,500′ altitude, and that oil occasionally drips from the front of the engine.
Power is delivered to the rear wheel via a four-speed transmission shifted on the right as well as a drive chain.
