YOUR WORLD , YOUR PLAYGROUND
Suzuki has revealed all-new DR-Z4S and DR-Z4SM models , with the covers pulled off the dual sport and supermoto machines recently at Eicma in Milan , Italy .
Spiritual successors to the popular DR-Z400S and DR- Z400SM models of the noughties , the two fresh 400s use a new twin-spar steel frame with a separate , bolt-on aluminium subframe and aluminium swingarm , housing a new 398cc single-cylinder engine . There ’ s also an electronics package that includes power modes , switchable ABS , and a sophisticated traction control system with offroad modes .
Designed to bring the fun to whatever environment , they promise to make Your World , Your Playground .
Powering both the DR-Z4S and DR-Z4SM is a new 398cc , single-cylinder , liquid cooled , DOHC four-stroke engine . The new engine was designed to meet Euro 5B , while maintaining the reputation of robustness and reliability the engine found in the previous generation DR-Z400 was famed for . It provides a smooth , linear power delivery with stronger torque at lower rpm and increased power output to the rev limit , plus improved fuel economy . When compared to the previous DR-Z400 engine , there are changes to almost every aspect , from lightweight titanium intake valves and hollow , sodium-filled exhaust valves to new cam profiles and piston . A new cylinder head is equipped with twin spark plugs , there are new crankcases , and a new slipper clutch with Suzuki ’ s Clutch Assist System .
Fuelling comes courtesy of a ride-by-wire , 42mm bore , electronic throttle body and a 10- hole fuel injector . There ’ s a new air box , and a new exhaust . The result is a broader spread of power across the rev range , strong drive yet smooth ride , a direct , linear throttle response , and improved fuel economy .
Peak power is 38PS at 8,000rpm , with a peak torque figure of 37Nm at 6,500rpm . Both achieve over 80mpg .
Both models use a package of carefully selected , ride-enhancing electronic aids ; the Suzuki Intelligent Ride
System .
Suzuki Drive Mode Selector ( SDMS ) means riders can choose from one of three power modes . Each mode reaches the same peak power output , with A the most direct , delivering the full amount of low-down torque available from the 398cc single-cylinder engine . Modes B and C are progressively softer , allowing riders to dial back the initial power delivery to suit in slippery or low grip conditions .
There are two standard traction control modes on both , with each also equipped with its own specific G ( gravel ) mode . G mode aims to maintain maximum offroad performance by allowing a certain amount of wheel spin . G mode ’ s level intervention is set slower than for the traction control system ’ s other two standard modes , and the maximum level of intervention is also set lower , too . This provides the right balance between preventing excessive wheel spin on slippery surfaces and minimising power loss on surfaces with traction , making the bike easier to control .
On the DR-4S it focuses on enabling riders to enjoy offroad riding with confidence . It does so by adopting an updated version of the system when compared with the application on the V-Strom 1050DE and V-Strom 800DE , by being effective not only on flat surfaces but also on undulating terrain and inclines . On DR-Z4SM it is tailored more towards flat-dirt surfaces , while allowing a little more slip tolerance than on the V-Strom DEs . Allowing more spin lets the rider better tap into the model ’ s supermoto character .
Further enabling greater control off-road is an ABS system that riders can tailor to their needs and riding conditions . On the DR-Z4S riders can disengage the ABS at the rear , or at the front and rear . On the DR-Z4SM , riders can disengage the rear ABS .
There ’ s also Suzuki ’ s easy-start system , which means the engine fires up with one press of the starter button , and there ’ s no need to pull the clutch lever when starting in neutral .
