2026 Suzuki DR-Z4SM Sky Grey

Engineered for Power

The 398cm3 single-cylinder four-valve DOHC engine delivers smooth, controllable power from low rpm through to the high end of its operating range.

Dual Spark Efficiency

The dual spark plugs help maximize combustion efficiency and performance across the engine’s operating range.

Innovative Exhaust Design

The exhaust pipe complies with noise regulations and features a double-wall design that helps protect the rider’s legs from extreme heat, while also contributing to a slim body profile.

Lightweight, High-Performance Valves

Lightweight titanium intake valves and hollow sodium-filled exhaust valves contribute to maximizing combustion efficiency and performance.

Enhanced Piston for Smooth Power

The piston design helps achieve smoother engine operation while reducing mechanical loss.

Efficient Fuel Injection

The fuel injection system features easier starts, especially when the engine is cold, and employs 10-hole injectors that maximize fuel atomization for better combustion efficiency and lower fuel consumption. The DR-Z4SM offers riders precision fuel-air balance. By achieving the ideal fuel-air ratio, the engine features satisfying response as the rider begins to open the throttle.

Responsive Electronic Throttle

The 42mm bore electronic-controlled throttle body helps improve output and deliver a faithful response to throttle action.

Durable, Responsive Twin-Spar Chassis

The pipe steel twin-spar frame remains plenty capable of withstanding rough conditions, while also contributing to nimble handling that responds faithfully to the rider’s will.

Lightweight Aluminum Seat Rails for Strength

High-Performance Wheels and Tires

The DR-Z4SM rides on wire-spoke wheels. The 17-inch front wheel and 17-inch rear wheel are shod with IRC GP-410 dual-purpose tube-type tires (120/70R-17M/C 58H at the front; 140/70R-17M/C 66H at the rear) that feature an interior structure custom-engineered exclusively for the DR-Z4SM.

Built to perform optimally, whether negotiating off-road trails or riding on roads, these tires feature chunky center blocks that provide solid grip and contribute to the model’s outstanding controllability.
