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.

Equipped with Suzuki Intelligent Ride System...

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.

• New camshaft profiles have increased intake lift and optimized valve overlap, contributing to both improved engine performance and world-wide emissions compliance. The valve spring rates have been increased to match the increased intake valve lift. Like a GSX-R, the DR-Z4S’ shim-under-bucket valve adjustment system has long service intervals.

• 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.

• Riding on durable steel sprockets, a strong O-ring style drive chain contains lubrication pre-packed between the pins and rollers for quiet, reliable operation.

• The redesigned trim frame combines cast components with thin chrome-moly steel tubes for exceptional torsional rigidity with minimal weight
