Standard buyer overview
The DR-Z4S order should identify the S dual-sport configuration, because the DR-Z4SM shares the engine family while using a different wheel and chassis setup. Factory product information gives DR-Z400SRJM5 for the S brochure family. That is a useful reference when discussing the current generation, but the supplied motorcycle's own identification still matters for parts, accessories and service instructions. The S on this page is listed at 151 kg kerb weight with a 920 mm seat and an 8.7-litre tank. Establish those details before treating a generic DR-Z advertisement as a description of the bike being quoted.
The 398 cc engine uses a single cylinder, liquid cooling and DOHC valve operation. Its 90.0 mm bore, 62.6 mm stroke and 11.1:1 compression ratio accompany fuel injection and electric starting. A five-speed constant-mesh gearbox provides the conventional motorcycle controls. The dry-sump lubrication arrangement is also part of the identity and should guide the service procedure. Do not assume that filling or checking oil works exactly as on a different Suzuki road bike. Ask for the applicable manual and keep the model identification with it, particularly if the DR-Z4S is a new type of motorcycle for you.
The tall seat is the fit issue to settle first. At 920 mm, it deserves a controlled demonstration of stopping, supporting the motorcycle and moving it at walking speed. The 151 kg kerb mass cannot be assessed independently of that height. Try the normal seated position and the position on the pegs you expect to use, paying attention to the relationship between knees, bars and controls. If the stock has been lowered or fitted with a different seat, have that configuration and any resulting changes identified separately. A modified display bike may not represent the height of the standard motorcycle on the order.
The S's 300 mm ground clearance and long suspension travel are key reasons to choose this derivative. The retained figures are 280 mm front and 296 mm rear, using an inverted front fork and link-type rear suspension. Adjustment should be understood from the supplied instructions and matched to the permitted load. More travel does not automatically mean a comfortable setting for every rider or terrain. Establish the baseline before making changes, and avoid copying a supermoto setup simply because both models use the DR-Z4 name. The different wheel sizes and intended chassis arrangements deserve separate treatment.
Front and rear tyres are 80/100-21 and 120/80-18, with tube-type fitment. Plan puncture equipment and replacement choices around that actual arrangement. The disc dimensions supplied for this configuration are 270 mm front and 240 mm rear. The S's retained ABS description permits rear-only or both-wheel deactivation, while the SM keeps its front ABS active when the rear is switched off. That difference is meaningful equipment information. Have the dealer explain the selection procedure, indications and restart behaviour from the exact manual, rather than relying on an abbreviated statement that both motorcycles have switchable ABS.
Traction control offers two road modes, gravel mode and off in the factory description. The LCD instruments and LED lighting bring current electronics to the dual-sport package. Check the display and switches with riding gloves and from the posture you will use. A mode designed for a particular situation still requires the rider to understand surface conditions and the motorcycle's limits. The objective of the handover explanation is confident operation of the actual controls, not an assumption that an electronic mode can compensate for inappropriate tyres, excessive load or unfamiliarity with a tall motorcycle.
The 8.7-litre tank calls for realistic fuel-stop planning, especially on routes with long gaps between facilities. The factory regional WMTC information is retained as Equivalent: 28.4 km/L, approximately 3.5 L/100 km, and 82 g/km CO2 for the shown specification. It is not a guaranteed South African range or a promise about fuel use away from the test conditions. Any luggage or carrier should be suitable for the exact S and its stated limits. The combination of long suspension and a single-cylinder engine does not establish how much passenger or accessory weight can be added.
Choose this DR-Z4S configuration when the tall dual-sport format, larger front wheel and suspension travel are deliberate priorities. Compare the DR-Z4SM if your interest is primarily a supermoto setup, and a V-Strom if your priorities include a different seat, tank and travel arrangement. Obtain a current itemised South African quotation and the warranty and servicing conditions for the intended use. Accessories and any lowering changes should be described explicitly. The value of the S rests on its own geometry and equipment meeting the rider's needs, not on treating every motorcycle with the DR-Z name as the same product or promising capabilities that a specification sheet cannot establish.
The S also lists a 1,490 mm wheelbase against the SM's 1,465 mm. That twenty-five-millimetre difference is another reminder that the two chassis specifications should remain distinct, even though their engine dimensions match.
