Dual sport and off-road riding enthusiasts are surely already familiar with the Suzuki DR series.

One of the latest models to carry the DR banner is the 2013 Suzuki DR-Z400S. It’s a great trail bike that happens to be street legal; enabling riders to enjoy the best of both worlds in terms of off-road adventure and maneuvering though crosstown traffic. Dual-sport bikes are machines that combine rugged off-road capability with comfortable on-road manners. Dual-sport models deliver riders absolute freedom to ride city streets and transition to trail busting without missing a beat. The DR-Z400S is a street legal bike that was designed for serious dirt bike riders. It’s a fun bike for taking twisting forest trails or winding around rolling canyon with. The bike’s torque four-stroke engine delivers great performance at low rpms and excellent throttle response.
The 2013 DR-Z400S is powered by a 398cc, liquid-cooled, four-stroke engine that was tuned with low-rev torque delivery in mind. The bike features a dry-sump lubrication system that helps minimize its weight and provides it with the kind of ground clearance needed for conquering rugged trails. The 2013 Suzuki DR-Z400S is also relatively light in weight, thanks to a magnesium-alloy clutch, magneto, and cam covers. The five-speed transmission and manual clutch connect engine power to the pavement with a chain final drive. Out front there’s a 21"" wheel that contributes to the DR-Z’s rugged looks while combining with the bike’s 18"" rear wheel to maximize the DR’s ability to handle boulders, bumps, and gaps in the trail. The bike has a compact five-speed transmission that employs a cable-operated clutch with a separate outer cover.

The bike’s throttle position is monitored by a digitally mapped DC-CDI ignition system that also helps maintain efficient combustion. The engine features a forged aluminum piston that’s 10 percent lighter than a cast iron one would be. A crankshaft oil jet provides additional oil cooling to the engine. Throttle response is smooth and even thanks to a Mikuni 36mm carburetor that’s fed by a six-liter air box.
