1989
The 1989 Suzuki DR Big 750 S holds a significant place in the history of large-displacement adventure motorcycles. Precursor to the legendary DR800S, this model was part of Suzuki's pioneering efforts in the dual-sport segment, aiming to offer robust off-road capability with long-distance touring potential. At its introduction, it competed directly with other big thumper adventure bikes like the Honda XRV650 Africa Twin and the Yamaha XTZ 750 Super Ténéré, carving out its own niche with its distinctive styling and imposing presence.
Powering the DR Big 750 S is a substantial 727.0 ccm (44.36 cubic inches) single-cylinder, four-stroke engine. This large thumper design was chosen for its strong low-end torque, ideal for navigating varied terrain. While not built for outright speed, its top speed is a respectable 120.0 km/h (74.6 mph), sufficient for most touring and adventure riding scenarios. A key feature for long journeys is its enormous 29.00 litres (7.66 US gallons) fuel tank, offering an impressive range between fill-ups, a crucial aspect for exploring remote areas where fuel stations are scarce.
Riding characteristics of the DR Big 750 S are heavily influenced by its adventure lineage. Riders experience an upright stance, providing excellent visibility over traffic and terrain. The long-travel suspension, typical of the era's dual-sport machines, effectively absorbs bumps and imperfections, contributing to a comfortable ride over extended periods. While its size and weight are noticeable, especially at low speeds, the motorcycle feels surprisingly balanced once in motion, making it capable on both graded dirt roads and less technical trails.
The Suzuki DR Big 750 S was designed for the adventurous rider seeking a reliable, go-anywhere machine with a focus on endurance rather than outright speed. Its generous fuel capacity and robust single-cylinder engine make it an ideal choice for long-distance touring and overland expeditions. It appeals to enthusiasts who appreciate classic adventure styling and the mechanical simplicity of a large thumper. For those who prioritize rugged dependability and a distinctive riding experience, the 1989 DR Big 750 S remains a compelling choice within the vintage adventure market.
✅ Why buy this bike?
• Unique, distinctive styling with the original 'beak' design, making it a true head-turner and collector's item. • Comfortable ergonomics and plush suspension make it excellent for long-distance touring, even with reduced power. • Robust, under-stressed engine in reduced effect form ensures legendary Suzuki reliability and longevity. • Excellent ground clearance and decent suspension travel for tackling light off-road trails and rough roads. • Strong torque delivery from the large single-cylinder engine, useful for relaxed cruising and carrying luggage. • Relatively simple mechanics for a big thumper, making home maintenance and repairs more manageable.⚠️ Things to consider
• Reduced effect significantly limits top-end power, making highway overtaking and spirited riding a slower affair. • Heavy for a single-cylinder machine, especially at low speeds and when maneuvering, challenging for smaller riders. • Vibrations from the large single-cylinder engine can become tiring on longer rides, even with counterbalancers. • Braking performance is adequate but not exceptional, requiring more planning, especially with the bike's weight. • Finding specific spare parts for this older, niche model can be challenging and potentially expensive.Rule of thumb: under 125cc / 15HP → A1, under 47HP → A2, above → A.
