2025 Suzuki DR-Z4S Solid Iron Gray The next evolution of Suzuki’s DualSport heritage has arrived with the all-new 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 (S.I.R.S) the DR-Z4S puts advanced riding aids at your fingertips. With features like the three-level Suzuki Drive Mode Selector (SDMS), four-mode Traction Control System, and switchable ABS, riders can customize their ride. The new LCD display offers essential ride information, so you can monitor settings with ease whether navigating twisty roads or a technical trail. In addition to these new features is fully adjustable KYB suspension for precise handling and new IRC tires for optimal grip. The DR-Z4S comes with off-road prowess, making this motorcycle suited for both road and trail. Sleek LED lighting, vibrant body colors, and ergonomic touches complete the package, positioning the DR-Z4S as Suzuki’s latest benchmark in DualSport innovation. Features May Include: Key Features - New twin-spar steel frame and aluminum sub-frame give exceptional torsional rigidity and greatly enhance the DR-Z4S’ handling characteristics. - New piston design helps achieve smoother engine operation while new radiator with larger fan diameter improves cooling. - Fully revised 398cc single-cylinder four-valve DOHC engine delivers a smooth, controllable spread of torque from low RPM up through peak power. New higher-lift camshafts with reduced overlap press upon new titanium intake valves. - Now equipped with Electronic Fuel Injection, the DR-Z4S’ engine is fed through an electronically controlled (Ride-by-Wire) throttle body with a 42 mm bore and a 10-hole injector that significantly improves engine response, idle speed control and peak power output. - Minimalistic and sleek, styling visually confirms that the DR-Z4S is an extremely capable off-road motorcycle. Riders can choose the iconic Champion Yellow No. 2 / Solid Special White No. 2 bodywork or the stealth-like Solid Iron Gray plastics that blend well with the many blacked-out chassis components. Engine Features - 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. Transmission Features - 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. - The transmission’s output is managed by the Suzuki Clutch Assist System (SCAS). This system works like a slipper clutch by allowing a small amount of clutch slip under deceleration for smoother downshifts. The SCAS also works as an assist clutch, increasing plate pressure under acceleration, but always keeps the clutch lever’s pull light and precise. This large-diameter, wet, multi-plate clutch uses a precise cable-activated release, providing the rider with a light pull and a superb friction-point feel. Chassis Features - 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
