1988 | DR750S
Desert Express equipped with a big 750 cm³ single-cylinder engine
The DR750S is a replica model of the DR-Zeta factory rally bike and combines the toughness and reliability developed using know-how cultivated under harsh and challenging race conditions. It features a lightweight and compact easy-to-maintain 750 cm³ 4-stroke oil-cooled 1-cylinder SOHC 4-valve engine with revolutionary dual slingshot carburetors delivering the air-fuel mixture to the big single cylinder. This engine generates ample torque and quick response from low and medium revs right up to the high-rpm range. A thorough approach to reducing the size and weight of the chassis and lowering the center of gravity was instituted from the design phase, resulting in a superb balance between high-speed stability and rough road handling.

1990 |DR800S
Even more competitive off-road model with a larger engine displacement of 800 cm³
Ample engine performance was realized by lengthening the piston stroke by 6 mm and increasing the displacement by 52 cm³. The DR-Zeta rally bike, which was based on the DR800S, was ridden in the Paris-Dakar Rally by Gaston Rahier, who won the 125 cm³ Motocross World Championship (MXGP) for three consecutive years between 1975 and 1977. The exterior design is unchanged from the DR750S, and features a front fairing that extends from the fuel tank to beyond the headlight, creating the impression of a bird’s beak. This popular and totally unique design feature was inherited by the V-Strom 1000 (2014), 650 (2017), and 250 (2017).
