DR-Z4S

Engine Key Features

• The compact 398cm³ liquid-cooled DOHC dry-sump engine has been refined to improve its torque and responsiveness, achieving an exceptional balance of performance and handling while meeting the latest emission and noise standards.
• New camshaft profiles achieve greater intake lift and improved valve overlap, which enhance engine performance while ensuring compliance with Euro 5+ standards.
• The cylinder head boasts a new design with optimised intake port and intake valve periphery shapes along with a smooth, flat combustion chamber. This enhancement leads to improved combustion efficiency, providing excellent durability at low loads and strong power output at high loads.
• New piston and crankcase designs combine to reduce mechanical loss by up to 20% and contribute to smoother engine operation, increased power output right up to the rev limit, and improved fuel economy.
• The engine is fed by a 42mm bore electronic-controlled throttle body that helps achieve a fine balance between idling speed control and power output characteristics
• The exhaust system is equipped with a dual-stage catalytic converter that helps satisfy Euro 5+ emissions standards.
• Revised air cleaner box and inlet tube design helps reduce resistance, improving low-end torque production and power output.
• New radiator with larger fan diameter improves cooling.

The Suzuki Intelligent Ride System (S.I.R.S.) features a collection of advanced electronic rider assist functions including:

• Suzuki Drive Mode Selector (SDMS): The rider can select between three modes that deliver different power characteristics to match the riding conditions. All power modes build to the same peak power.

Mode A provides the sharpest response as the throttle is opened. Tuned to deliver exciting acceleration and fully leverage the engine’s power.

Mode B features a more linear curve with softer initial throttle response, to deliver a satisfying balance of settings that make a good fit for a broad range of riding styles and road conditions.

Mode C gives the softest throttle response and more gentle torque characteristic. This setting is a good choice when riding on loose or otherwise slippery surfaces.

• The Suzuki Clutch Assist System (SCAS) works as an assist clutch to make the lever easier to pull while transmitting the power output, reducing fatigue.
• Suzuki Traction Control System (STCS) helps prevent rear wheel spin, enabling you to better control the bike in diverse and varying conditions. In addition to G (Gravel) mode, you can select between two standard on-road modes. Mode 1 is intended for dry paved surfaces, while Mode 2 is intended for wet paved surfaces, taking effect more quickly to be more proactive in limiting wheel spin. You can also opt to turn the system off entirely Note: Traction control is not a substitute for the rider's throttle control. It cannot prevent loss of traction due to excessive speed when entering turns, or while braking. Nor can it prevent the front wheel from losing traction.
• G (Gravel) mode allows a limited amount of tyre slip when riding on unpaved surfaces so the bike remains controllable, while at the same time delivering the consistent power output you want for exploring unpaved roads and country trails with greater confidence.
• Switchable ABS:The DR-Z4S is the first Suzuki production model that lets you switch ABS OFF for both the front and rear brakes to take full control over braking when riding off-road. Alternatively, you can opt to turn off ABS for the rear wheel alone.
• Suzuki's Ride-by-Wire Electronic Throttle System gives greater controllability over the engine and helps harness that power effectively.
• The Suzuki Easy Start System starts the engine with one quick press of the starter button, even without pulling in the clutch when the transmission is in neutral.

Key Chassis Features

• All new frame designed to respond faithfully to your will. The steel frame is rigid yet supple enough to handle rough surfaces, and absorb impact to reduce rider fatigue.
• The lightweight aluminium swingarm, with its distinctive design, enhances tracking and rear suspension responsiveness, leading to a smooth and comfortable ride.
• Long travel suspension featuring adjustable KYB inverted front forks with a long 280 mm suspension stroke and KYB rear suspension with 296 mm of rear wheel travel provide stability and precise handling.
• Light, strong and flexible, the tapered aluminium handlebars fitted with half-waffle grips provide a solid grip, positive control, and help reduce fatigue.
• An upright riding position that offers excellent control for off-road with stability while ensuring stability and comfort for extended journeys.
• The standard-equipment aluminium under cover protects the engine
• Wide rider footpegs.
• The lockable toolbox has been repositioned to the side for greater convenience.

Key Electric Equipment Features

• Both high and low beams are incorporated into one bright LED projector.
• LED rear combination light and license plate light.
• Newly designed full LCD instrument panel.
