The announcement of Suzuki’s latest dust-capable, dust-oriented motorcycle marks a significant milestone for the brand. Known for its commitment to innovation and rider satisfaction, Suzuki recently hosted a major unveiling event in Portland, Oregon, three weeks ago, at the scenic Tillamook State Forest. The focus was on the new DR-Z model, which retains its core heritage while integrating modern advancements. Suzuki is proud to present the updated DR-Z, which now features fuel injection to comply with the latest emission standards, all while preserving the bike’s signature design elements-from the twin-spark head to the perimeter frame.
Despite the modern updates, the essence of Suzuki’s design philosophy remains evident once you’re on the bike. The new DR-Z4S is a direct descendant of the legendary DR-Z400S, with a sleek, more refined silhouette, a less abrupt junction between the seat and fuel tank, and a more contemporary riding stance. Suzuki claims the engine produces approximately 37.5 horsepower at 8,000 rpm, which aligns with our impressions of the bike’s performance. The power delivery feels more efficient, with a broader torque curve that begins earlier in the rev range, making it more responsive and easier to handle in various riding conditions.
One of the most notable improvements over its predecessor is the elimination of the problematic CV carburetor, which previously caused hiccups and inconsistent throttle response in rough terrain. The new fuel-injected system ensures smooth, predictable power delivery from the bottom end to the top, eliminating the herky-jerky throttle issues that plagued earlier models. Additionally, Suzuki retained the five-speed gearbox, which, despite its high first gear and low fifth gear, provides a familiar and reliable shifting experience. This setup is ideal for riders who want a versatile bike capable of both trail riding and highway cruising.
During our test ride in Oregon’s lush, rocky terrain, the bike demonstrated impressive agility. The environment was characterized by small, chilly creeks and a vibrant palette of greens, providing an ideal backdrop for testing the bike’s capabilities. Suzuki’s innovative Traction Control System, which includes three distinct modes-A, B, and C-was particularly useful. Mode A is designed for aggressive riding, while Modes B and C are more suitable for beginners or casual riders. The standout feature, however, is the Gravel Mode, which offers a unique advantage: it allows controlled rear-wheel slip on loose, rocky surfaces. This feature helps prevent wheel lock-up and maintains momentum, making it easier to navigate challenging off-road conditions without abrupt power cuts.
Handling-wise, the DR-Z4S is somewhat limited by its tires, which are primarily designed for paved roads. The IRC Path Winner tires excel on asphalt but may not provide the same grip on loose dirt or gravel. Given the bike’s weight-over 300 pounds-riders should temper their expectations when pushing through tight, technical sections. Nonetheless, the bike remains surprisingly nimble in challenging off-road segments, demonstrating Suzuki’s commitment to creating a dual-sport that balances on-road comfort with off-road capability. For a comprehensive review, check out the detailed test in the August 2025 issue of Dirt Bike magazine.
Historical Roots of the Suzuki DR Series
The Suzuki DR-Z400S has long been regarded as a solid investment in the dual-sport market. When it debuted, its price was set at $5,349, making it accessible for many riders. Over the subsequent 25 years, the model’s core design remained largely unchanged, with resale values often matching or exceeding the original purchase price-testament to its enduring appeal. Originally conceived as a dual-purpose bike, the DR-Z was not initially aimed at racing but rather at riders seeking a reliable, versatile machine for both on- and off-road adventures. Nonetheless, the Yoshimura Suzuki Off-Road team built high-performance versions that dominated in competitive events, with Mike Kiedrowski clinching WORCS championships in 2002 and 2003 on the DR-Z platform.
When Suzuki introduced the RM-Z450, the focus shifted more toward motocross and off-road racing, leading to the discontinuation of the off-road-oriented DR-Z models. The dual-sport variant, the DR-Z400S, remained a popular choice for riders who wanted a dependable bike for everyday riding and weekend adventures. Suzuki’s understanding of dual-sport needs has always been rooted in its history of producing bikes that excel both on and off the trail, a philosophy that continues with the latest DR-Z4S.
Legendary rider Mike Kiedrowski, who nearly retired from professional motocross, was persuaded to stay active by Suzuki’s off-road manager Mike Webb. His decision led to back-to-back WORCS championships on the DR-Z400, cementing the model’s reputation for durability and performance in competitive environments.
Yamaha’s 1968 DT-1 is often credited as the first true dual-sport motorcycle, but Suzuki’s 1969 TS250 Savage quickly gained recognition for its superior performance. Cycle Magazine compared all 250cc bikes of that era and declared Suzuki’s offering the best, highlighting its balanced combination of power, reliability, and versatility. Before Suzuki shifted focus exclusively to four-stroke models in 1977, it produced a range of two-stroke dual-sports, including the notable SP370 introduced in 1978, which further cemented Suzuki’s reputation in this segment.
In 1990, Suzuki expanded its dual-sport lineup with the air-cooled DR350 and DR250, both of which served as capable trail and street bikes. Notably, rider Randy Hawkins competed on a modified DR350 in the International Six Days Enduro (ISDE), demonstrating the model’s off-road potential despite its comfort-oriented design. The evolution of Suzuki’s dual-sport bikes reflects a continuous effort to blend rugged off-road capability with everyday practicality, a tradition that persists today with the new DR-Z4S.
When the DR-Z400 was introduced, it marked a significant upgrade, and rider Trace Tilley campaigned a modified version in the AMA Four-Stroke Championship, showcasing its competitive edge. Although the DR-Z family has seen various iterations, the core philosophy remains unchanged: to provide a reliable, versatile dual-sport machine that can handle both the trail and the highway with equal ease.
Throughout its history, Suzuki has been a key player in the dual-sport segment, consistently delivering bikes that appeal to a broad range of riders-from casual trail riders to competitive racers. The latest DR-Z4S continues this legacy, combining modern technology with Suzuki’s proven design principles to meet the demands of today’s dual-sport enthusiasts.
