The Suzuki DR-Z400SM is a street legal bike for serious dirt
bike enthusiasts on pavement roads. It's not uncommon to take the
SuperMoto down twisty forest trails as well as tight canyon corners. Its
398cc liquid-cooled, four-stroke engine provides strong low-rpm torque
and crisp throttle response for any of these occasions. The key
difference from the DR-Z400SM and the DR-Z400S are the inverted forks.
Inverted front forks contributes to less unsprung weight and improved
overall handling. The SuperMoto also comes with wider rims and stickier
tires than the dual-purpose 400S.
