Triumph Speed Twin Motorcycle - Street (1950-2026)

The Triumph Speed Twin, produced from 1950 to 2026, is an iconic model that spans two distinct eras. Originally launched in 1937, the classic Speed Twin made motorcycle history until 1966, setting the standard for parallel-twin engines. After a significant hiatus, Triumph reintroduced the name in 2019 with modern models. The classic period (1950-1966) featured the 5T model with a 498cc engine, followed by the 5TA from 1959, which boasted a 490cc unit construction engine (engine and gearbox sharing a common casing). Notable developments included the switch from a magneto/generator electrical system to a Lucas alternator in 1953, and the adoption of swinging arm suspension around 1955. The famous "bathtub" fairing was introduced with the 5TA, later abbreviated to "bikini" before being removed in 1966. Modern models (2019-2026) include the Speed Twin 900 (formerly Street Twin, rebranded in 2022) and the Speed Twin 1200. These motorcycles are equipped with liquid-cooled parallel-twin engines, 900cc and 1200cc respectively. They have received regular updates, including improved brakes, higher-spec forks, Euro 5 compliant engines, and the introduction of special editions such as the Chrome, Stealth, Cafe Racer, and TFC. These evolutions reflect Triumph's commitment to modernizing its classics while retaining their spirit. Q: Is this product compatible with my Triumph Speed Twin?
