2023 Suzuki DR-Z400SM
Suzuki’s 2023 SuperMoto DR-Z400SM is based on the proven DR-Z400S. So it combines Supermotard style and features in a narrow, lightweight, street-legal package. This bike brings off-road soul and fun to paved roads. It’s not uncommon to take the SuperMoto down a twisty forest road, around tight canyon corners, or through commuter traffic.
Its 398cc, liquid-cooled, four-stroke engine provides strong low-rpm torque and crisp throttle response for any of these occasions. Key differences between the DR-Z400SM and the DR-Z400S are the inverted front fork, wide spoke-style wheels, and 300mm diameter floating front brake rotor. The inverted fork contributes to less unsprung weight and improved overall handling, while the large brake and wider rims with high-grip tires offer an exhilarating sportbike experience.
