Suzuki T20
Two-stroke, twin-cylinder motorcycle
The Suzuki T20 is a motorcycle with a 247 cc (15.1 cu in), two-stroke, twin-cylinder engine, and six speed gearbox. It was first manufactured in 1965 (but introduced as a 1966 model) and was produced until the end of the 1968 model year. Production peaked at more than 5000 units per month. It was superseded by an updated version which was designated the T250-1. In the United States, the bike was sold as the Hustler, a name also used by Suzuki for the Suzuki Hustler kei car since 2014.
Marketing
In the UK the T20 was called the 'Super Six' which refers to its - at the time - very unusual six speed transmission. In that era most motorcycles had only four speeds or, rarely, five speeds. In the USA the bike was designated the X6 with the advertising department tacking on the "Hustler" name.
Advertising brochures produced by Suzuki listed the following features to be found on the new model:
Claimed power of 29 hp
Claimed weight of 135 kg (298 lb)
Racing type double leading shoe 8 inch front brake
Aluminium alloy twin cylinder engine
Close ratio 6-speed transmission
Twin 24 mm carburettors
POSI-FORCE lubrication
Air pump
Scientifically designed quiet efficient mufflers
Safe powerful 8 inch rear brake
Wide type tail lamp
Safe bright turn signal lamps
3 position adjustable shock absorbers
Wide, comfortable dual seat
14-litre (3.7 US gal) gasoline tank
Racing type throttle
Easy-to-read tachometer and speedometer
Sturdy oil damped telescopic front fork
12 volt fully approved lighting system
In the US, Suzuki first opened a showroom featuring the X6 Hustler in Santa Monica, CA (in late 1964 or early 1965) and shortly after (in June 1965) opened a second showroom (the first on the US east coast), named Cycle City, located in Newport News, Virginia.
Posi-Force system
The T20 was equipped with a 247 cc two-stroke engine, which meant that oil needed to be mixed with gasoline prior to injection into the cylinder.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Suzuki T20”, the useful work is to connect “two-stroke, twin-cylinder motorcycle” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 25, 2026. The linked authority identifier is Q392224. The first chronological checks are 1965, 1966, 1968 and 2014.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
