2025 Suzuki DR-Z4S

2025 Suzuki DR-Z4S

The next evolution of Suzuki’s DualSport heritage has arrived with the all-new 2025 DR-Z4S. This new model redefines versatility and performance, built for riders who want the best of both worlds. Starting with an all-new twin-spar steel frame and aluminum subframe, Suzuki engineers have crafted a chassis that enhances stability and handling across diverse terrains. At its heart, the fully redesigned 398cc engine now features electronic fuel injection and Ride-by-Wire throttle body, delivering a refined, torque-filled performance.

Features may include:

• The DR-Z4S is powered by a thoroughly updated 398cc single-cylinder four-valve DOHC engine that delivers a smooth, controllable spread of torque from low RPM up through peak power. The redesigned cylinder head has optimized shapes for the intake port, intake valve boundary, and a smooth, flat combustion chamber that produces better combustion to provide consistent power under low loads with strong power output under heavier loads. The DOHC cylinder head contains a pair of lightweight titanium intake valves and a pair of hollow, sodium filled exhaust valves that help maximize combustion efficiency and performance.

• Every aspect of the new air cleaner box design was studied and updated, including its capacity and outlet shape, to improve intake air flow. The length of the inlet tube and the diameter of its mouth were designed to achieve balance between intake air sound and the engine’s power delivery to generate sharp throttle response and powerful low-speed torque. The left side body cover has a quick-release fastener, and swings open like a door, retaining the popular, easy access to the air filter element.

• The revised, compact, five-speed transmission utilizes a cable-operated clutch with a separate outer cover for simplified clutch maintenance.

• Most of the gears and shafts in the transmission were updated to reduce oil windage (drag) and to increase strength.

• Supplied by KYB, the new long stroke inverted cartridge-style fork with 11.0 in. (280 mm) of travel has adjustable compression and rebound damping force for smooth performance on all types of on- and off-road terrain. The new frame and fork also update the fork rake and trail specifications for a balance of nimble handling and straight-line performance. The new, rear KYB shock absorber has 11.6 in. (296 mm) of rear wheel travel with spring preload plus both compression and rebound damping force adjustments, and connects to a new, lightweight aluminum swingarm through a progressive linkage system.

• The DR-Z4S’ new bodywork features Suzuki Champion Yellow No. 2 / Solid Special White No. 2 or Solid Iron Gray bodywork with modern graphics. The bodywork smoothly fits together, creating a “linear connection” from front to rear, through a bold horizontal line the flows from the front fender through to the tail. The MX-inspired styling also conveys the impression that the DR-Z4S is a serious off-road performer.

• Suzuki Traction Control System (STCS) continuously monitors front and rear wheel speeds, throttle opening, engine speed, and transmission gear. It quickly reduces engine output when it detects wheel spin by retarding the ignition timing and limiting the throttle opening. The rider can select one of four modes (1, 2, G, and OFF).

• The DR-Z4S is equipped with a compact, yet effective Bosch-supplied ABS control and is the first Suzuki production motorcycle with an ABS system with a Front & Rear ABS OFF mode that will deactivate the ABS function for both the front and rear wheels. The DR-Z4S also offers Rear ABS OFF mode, which switches off just the rear wheel ABS.
