Understanding the Suzuki DR-Z400S Transmission
The Suzuki DR-Z400S is equipped with a robust and reliable five-speed manual transmission. This transmission is a key contributor to the bike's adaptability, offering a good range of gearing for both low-speed off-road manoeuvring and higher-speed road cruising. The gear ratios are carefully selected to complement the 398cc liquid-cooled, single-cylinder engine, which produces a healthy 39 horsepower and 26 lb-ft of torque. This power delivery, combined with the five-speed gearbox, allows the DR-Z400S to feel lively and responsive in various riding conditions. The transmission is a constant mesh type, known for its durability and smooth shifting.
The clutch system is a cable-operated, wet multi-plate design. This type of clutch is common in motorcycles and offers good engagement and modulation. The outer cover for the clutch is made from magnesium alloy, which helps to reduce overall weight and also simplifies clutch maintenance – a thoughtful design choice by Suzuki.

Maintenance Considerations: Grease and Beyond
Regarding maintenance, a common query among riders is about the amount of grease on components like the swingarm and steering bearings. Unlike some other Japanese dual-sport or dirt bikes, the Suzuki DR-Z400S is generally noted for not having an excessive amount of grease on these particular parts. However, if you do notice any issues or are performing a thorough service, ensuring these bearings are properly greased is crucial for longevity and smooth operation. Changing the cam on older pre-built models of the DR-Z can sometimes provide relief, suggesting that specific component wear or adjustment might be beneficial in some cases. Always refer to your owner's manual or a service manual for the most accurate and detailed maintenance procedures for your specific model year.
The engine itself features a compact, 398cc, DOHC, liquid-cooled, dry-sump design. The dry-sump system means the engine oil is stored in a separate reservoir, which aids in keeping the engine's overall dimensions compact. The cylinder features Suzuki Composite Electrochemical Materials (SCEM) for durability and excellent heat transfer. The digitally-mapped DC-CDI system ensures efficient combustion by adjusting ignition timing based on throttle position and engine RPM. The forged aluminum piston is lighter than a cast piston and benefits from oil cooling via a crankcase oil jet. The Mikuni 36mm carburetor is fed by a six-litre airbox and includes a deceleration enricher circuit for smooth throttle response.
The chassis is equally well-thought-out. The narrow frame uses thin chrome-moly steel tubes for rigidity without adding excessive weight. The backbone tube, front down tube, and steering head gussets are designed to house the dry-sump engine oil. A bolt-on aluminium sub-frame further reduces weight and simplifies maintenance. The long-travel suspension, with a 49mm cartridge-style fork at the front and a linkage-type shock at the rear, is adjustable for damping and preload, allowing riders to tailor the bike's handling to different terrains and riding styles. The spoke-style wheels, with a 21-inch front and 18-inch rear, are shod with dual-purpose Dunlop D208 tyres and are ready to accept popular dual-sport tyres and rim-locks for more aggressive off-road use.
