Suzuki’s 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 glide 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 difference 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.

Live in a concrete jungle? Here’s your vine. Grab hold of our supermoto, the street hybrid that’s 80% dirtbike and 100% fun. Ride nice and tall in traffic, then dominate in rough road conditions where most other bikes have to back off.
