The Suzuki GS 750 was a Suzuki brand sports motorcycle with a transverse DOHC inline four-cylinder engine. When it was launched in 1976, it was the manufacturer's top model with a four-stroke engine and was to replace the two-stroke Suzuki GT 750 and the unsuccessful Suzuki RE 5 rotary motorcycle in the long term .

The GS 750 had a completely newly developed, short-stroke DOHC engine (bore / stroke: 65 × 56.4 mm) with two overhead camshafts that were operated via a timing chain with an automatic chain tensioner. The mixture was supplied by four 26 mm Mikuni carburettors, the ignition by a battery coil ignition . Despite the lower performance than the market leader Honda CB750 Four F1 , the Suzuki GS 750 won in comparison tests.

In addition to the engine at high speed reserves the chassis came with double loop tubular frame and reinforced top bar, Showa - telescopic fork with 140 mm travel and a needle bearing swingarm with 80mm of travel. Ernst Leverkus remarked "unusually good lane keeping for a Japanese machine." In tests, the predominantly neutral driving behavior, reliable straight-line stability and good cornering ability were praised.

"The 750 excelled in handling, performance and acceleration. No other machine in this category could match 4.5 seconds up to 100 km / h."

- Joachim Kuch, Jürgen Gaßebner.

Until the end of production, the Suzuki GS 750 was only slightly further developed and changed. When it was launched in Germany (GS 750 DB) in March 1977, a double disc brake was installed as standard. From 1978 cast wheels (GS 750 EC) for tire sizes 3.25–19 (front) and 4.00–18 (rear) as well as color and decor changes were available on request. In 1979 a chopper version (GS 750 LN) with a 4.50-17-inch rear wheel was offered. Depending on the source, between 3,800 and 5,000 Suzuki GS 750 were sold in Germany.

Processing of the RAF assassination attempt in 1977

Federal Prosecutor General Siegried Buback , his driver Wolfgang Göbel and the civil servant Georg Wurster were shot dead in their car on April 7, 1977 by assassins from the Red Army faction . The shooters had previously approached the car on a Suzuki GS 750 motorcycle and opened fire on Buback and his companions at a traffic light. On April 20, 1977, a full-page advertisement from Suzuki Germany appeared in the magazine Motorrad with the slogan:

"Suzuki - the sports cannon for snipers!"

- Suzuki.

The German Advertising Council found that the “advertisement had demonstrably been designed weeks before the murder, just as the magazine was printed before the attack.” However, the Advertising Council disapproved of “such an aggressive and military vocabulary” in motorcycle advertising. The motif was no longer used.

In 2013 the original crime motorcycle was shown in an exhibition in the Stuttgart House of History . The motorcycle was in the meantime in private hands and was redesigned compared to the vehicle with different handlebars, windshield, paintwork and luggage rack.

successor

The GSX 750 was introduced in 1980 as the successor to the GS 750 and was further developed, especially with the engine, now with four valves per cylinder. With a shorter-stroke design of 67 × 53 mm (bore × stroke), there was a 17 HP higher specified power of 80 HP at 9,200 rpm, which enabled a top speed of 200 km / h. There were other changes compared to the predecessor in the telescopic fork, slotted brake discs, transistor ignition , constant pressure carburetors as well as the angular headlights and the rear fairing.

In North America this model was further referred to as the 'GS 750'.
