The Suzuki DR-Z400 is a dual-sport motorcycle that Suzuki has built since 2000. Its 398 cc single is carburetted and liquid-cooled, and the model has been offered in four quite different forms, from a bare off-road machine to a supermoto.

History of the Suzuki DR-Z400
One engine, four bikes
The DR-Z400 appeared in 2000 with a 398 cc liquid-cooled four-stroke single fed by a carburettor. Suzuki sold it in four forms: the DR-Z400 with kick-start only, the DR-Z400E with electric start, the DR-Z400S with lights, indicators and mirrors for the road, and from 2005 the DR-Z400SM supermoto. The SM uses 17-inch road wheels, oversized front and rear brakes, an RM-Z rear swingarm and inverted forks.

Beyond Suzuki badges
Kawasaki sold a private-label version called the KLX400, nearly identical apart from bodywork and some accessories. The Australian Army also uses the DR-Z, slightly modified for military service.
Why it lasted
The formula of a light, simple single with long-travel suspension made the DR-Z400 a favourite for trail riding, commuting and supermoto racing alike, and the model has stayed in the range for more than two decades.
