Four-Stroke

Yamaha's first model with a four-stroke engine, after making only two-stroke machines since 1955. A slim 653 cm³ OHC vertical twin in an equally slim double-cradle frame answered the brief for a light, slim and compact large-displacement sports bike. Fans nicknamed it "Peke-S".

Since its debut in March 1978, the SR400 held its following with a simple, largely unchanged style and the pulse of its kick-started, air-cooled single. For the Japanese market the line concluded with the Final Edition Limited of 2021. Specifications listed are those of the 2021 Final Edition Limited.

The first model of the Katana series, known for styling inspired by the Japanese sword. Shown at the 1980 Cologne motorcycle show, it caused what Suzuki calls the “Cologne shock”, and production began the following year as an export model with a 1,074 cc air-cooled DOHC inline four.

A 750 cc supersport designed under Yamaha's "Genesis" concept, which sought a synergy between engine performance and handling stability. It used a liquid-cooled 749 cm³ DOHC inline four with five valves per cylinder, inclined forward 45 degrees; according to Yamaha, this engine was a world first.

Named after the serow, a goat-antelope, this 1985 "mountain trail" machine was developed for riding deep into mountainous terrain. A tractable air-cooled 223 cm³ four-stroke single sat in a light, slim chassis with a low seat, giving predictable handling that also suited town riding.

A 750 cc sports machine distilling Suzuki’s endurance-racing works machines, clothed in a full aerodynamic fairing and unveiled internationally at the 1984 Cologne show. Its oil-cooled DOHC 16-valve inline four (SACS) and an 8.1 kg aluminium-alloy frame brought dry weight down to 179 kg.

A chopper-style cruiser created by enlarging the bore of the 1985 VS750 Intruder by 3 mm to 805 cc. Its liquid-cooled SOHC 4-valve V-twin drove the rear wheel by shaft, plastic parts were kept to a minimum in favour of chrome plating, and a 685 mm seat gave a relaxed riding position.

Unveiled in 1994 amid the trend for unfaired "naked" bikes, the XJR1200 topped its class with what was then the largest displacement available. Its air-cooled 1,188 cm³ DOHC inline four offered strong low- to mid-range torque in clean-cut Yamaha styling. Specifications listed are for the 1995 model.

The second generation of the Bandit 400cc naked line that began in 1989. A flowing form from fuel tank to tail lamp was paired with a round headlamp and bullet-shaped meters. The 400V carried the VC engine, which switches cams according to engine speed, while radial tyres and an aluminium swingarm reduced weight.

A 400 cc cruiser introduced in 1996 as the successor to the Virago 400. A chrome-plated, air-cooled 399 cm³ V-twin sat in a chassis inspired by drag racing, with a low seat and long wheelbase. Gear ratios favoured the mid-speed range for city riding, and final drive was by shaft.

A 1998 supersport developed around the concept of "unsurpassed excitement" on winding roads. It paired a light, compact liquid-cooled 998 cm³ DOHC five-valve inline four with a Deltabox II frame. Specifications listed are for the overseas-market model.

Suzuki’s first 400 cc scooter, added in October 1998 above the 250 cc Skywave launched that February. A 385 cc liquid-cooled SOHC 4-valve single with a balancer shaft was combined with large 13-inch tyres, a link-type monoshock and linked front and rear disc brakes.

An export flagship developed under the “Ultimate Sport” concept. Styling modelled on Japanese armour and helmets for aerodynamics and wind protection, an aluminium twin-spar frame and a 1,298 cc liquid-cooled inline four with side cam chain combined to deliver 175 PS.

A dual-purpose machine intended for everything from off-road sport riding to touring and town use. A newly developed 398 cc liquid-cooled four-stroke DOHC 4-valve single sat in a split semi-double-cradle frame, for a dry weight of 129 kg, with adjustable suspension front and rear.

A maxi-scooter introduced in 2001, powered by a liquid-cooled 499 cm³ DOHC parallel twin driving through a V-belt CVT. Early models used a tubular steel frame. Specifications listed are for the 2001–2003 model years.

A 50 cc scooter pared down for short trips such as commuting, school runs and shopping. Built in Japan, it sold for 59,800 yen and weighed just 39 kg dry. Its newly developed air-cooled four-stroke OHV single used a high-speed plated cylinder, among other measures, to cut engine weight by 40 percent.

An export model introduced as a middleweight sport-adventure tourer. A 645 cc liquid-cooled 90-degree DOHC 4-valve V-twin sat in an aluminium twin-spar frame, with a 22-litre tank, a standard rear carrier, a screen adjustable to three heights and an 820 mm seat.

A 2019 adventure model with a liquid-cooled 689 cm³ parallel twin with a 270-degree crankshaft in a lightweight chassis. It balances off-road ability, adventure riding and touring, with freedom of riding position, durability, serviceability and luggage capacity. According to Yamaha, it is about 10 kg lighter than its XT660Z predecessor.

The Japanese-market version, released in 1990, of the VMAX that had debuted in the U.S. in 1985. It differed from the export model in parts of the liquid-cooled 1,197 cm³ V4, with an emphasis on drivability. Specifications listed are for the 1990 Japanese-market model.
