Triumph 3 TA

The 1965 Triumph 3TA, often affectionately known as the "Twenty One" due to its original 21 cubic inch engine displacement, represents a significant chapter in Triumph's storied history. Positioned as a mid-range offering, it appealed to riders seeking a capable yet approachable British twin. It belonged to the popular 350cc class, a competitive segment at the time, facing rivals such as the BSA B40 and the Norton Navigator. The 3TA continued the lineage of Triumph's unit-construction twins, a design philosophy that integrated the engine and gearbox into a single casting, a forward-thinking approach for the era that offered manufacturing efficiencies and improved structural rigidity.

At its heart, the 1965 Triumph 3TA was powered by a twin, four-stroke engine with a displacement of 349.0 ccm (21.30 cubic inches). This engine configuration provided a balanced power delivery, characteristic of British parallel twins. While specific power output figures for this exact year can vary, the engine was known for its reliable and tractable nature, making it suitable for a range of riding situations. The motorcycle carried a dry weight of 156.5 kg (345.0 pounds), a figure that contributed to its agile handling and manageable feel, especially when compared to some of its heavier contemporaries.

Riding the 3TA offered a classic British motorcycle experience. Its upright stance and comfortable seating position made it a practical choice for daily use and weekend excursions. The suspension, typical of the period, provided a compliant ride, absorbing road imperfections with reasonable effectiveness. While not a performance-oriented machine in the modern sense, its relatively low weight and twin-cylinder engine offered sufficient power for spirited riding on country roads. The braking system, usually drum brakes front and rear, provided adequate stopping power for the motorcycle's capabilities.

The 1965 Triumph 3TA was aimed at a broad spectrum of riders, from those graduating from smaller machines to experienced motorcyclists seeking a reliable and enjoyable mid-capacity twin. It was a motorcycle for the everyday rider, offering a blend of practicality and traditional British charm. Its relative simplicity and robust construction meant it was an accessible machine for maintenance and ownership. The 3TA's enduring appeal lies in its straightforward design, its classic aesthetics, and the distinctive thrum of its twin engine, making it a cherished classic for collectors and enthusiasts today.
