2007 SUZUKI DR-Z400SM
With the motorcycling crowd's enthusiastic response to supermoto-style bikes, Suzuki introduced theDR-Z400SM. Based on the hugely popular and extremely capable DR-Z400S DualSport machine, the 2007Suzuki DR-Z400SM combines the engine and chassis of the DR-Z400S with race-proven RM motocrossstyleforks and black-painted aluminum wheels. The result is a racy mix of on- and off-road performance.
New for 07 the DR-Z400SM now features a Renthal tapered aluminum handlebar for maximum rider controland minimal vibration. Also new for '07 the DR-Z400SM comes equipped with front and rear axle sliders.
The 2007 Suzuki DR-Z400SM employs a compact 398cc four-stroke, liquid-cooled engine tuned for a broadpowerband and low-rpm torque. The potent four-stroke also comes equipped with a four-valve cylinderhead, 36mm CV-type carburetor, Suzuki's own nickel-silicon-phosphorus-carbide-plated cylinder and a highperformance forged piston. Power is transferred through a smooth-shifting five-speed transmission, whilean electric start with auto-decompression system makes for quick and convenient starts. A thermostaticallycontrolled fan and radiator provide consistent operating temperatures in any environment.
The DR-Z400SM's chromoly steel frame is similar to that of Suzuki's RM motocross bikes, was designedwith maximum torsional strength and light weight in mind. The oil for the dry-sump lubrication systemresides in the frame's main backbone and front down tube for optimum efficiency.
Suspension for the DR-Z400SM consists of fully adjustable RM250-derived inverted front fork and a qualityrear shock. The rear shock also offers high- and low-speed damping adjustments as well as completelyadjustable spring preload and rebound damping. Oversize front and rear hydraulic disc brakes are mountedon black-painted aluminum wheels, as are 17-inch high-grip radial tires.
RM-inspired headlight housing and side panels decorate the DR-Z400SM, as does the slim-profile bodywork,which provides maximum rider mobility and comfortable seating. Rubber-mounted turn signals, asturdy engine guard and rear disc-brake cover offer protection against rocks and debris, regardless of theterrain. Air-filter maintenance is a simple affair, thanks to quick-release fasteners on the left side panel.
