Based on the Suzuki DR-Z400S dual-sport motorcycle, the 2021 Suzuki DR-Z400SM features 17-inch wire-spoke wheels with Dunlop Sportmax D208 tires, plus fully adjustable suspension with an inverted fork and linkage-assisted shock.

The DOHC single-cylinder motor is liquid-cooled and has electric start. However, it sticks with a 36mm Mikuni carburetor, a testament to the age of the design. This also means that the motor is fully sorted out, and there are plenty of available modifications to extract more power.
