For the first time since the introduction of the Suzuki DR-Z400S in 2000, the platform gets a significant update for 2025 in both the Suzuki DR-Z4S dual-sport and DR-Z4SM supermoto models. Changes include a revised engine, a new frame, new chassis components, new tech and rider aids, and new styling.
Starting with the engine, the Suzuki DR-Z4S and DR-Z4SM are powered by a 398cc Single with DOHC and four valves. It’s now fuel-injected and includes throttle-by-wire with a 42mm electronically controlled throttle body. Also new are a higher-lift cam profile, a new piston design, titanium intake valves, hollow sodium-filled exhaust valves, and Suzuki’s Dual Spark Technology with two iridium spark plugs. The air-cleaner box and inlet tube are also new. The redesigned engine makes a claimed 37.5 hp at 8,000 rpm and 27.9 lb-ft of torque at 6,500 rpm. Returning from the previous models is the 5-speed transmission.
Both bikes also get a new steel frame and aluminum subframe. New fully adjustable KYB suspension includes an inverted fork and a rear shock connected to a new aluminum swingarm with progressive linkage system. On the DR-Z4S, suspension travel is 11.0 inches front and 11.6 inches rear, while the DR-Z4SM supermoto gets 10.2 inches front and 10.9 inches rear.

Both bikes include the Suzuki Intelligent Ride System, including three ride modes, four traction control modes (including Gravel mode), and Suzuki Easy Start System. The Bosch ABS system can be switched off front and rear on the DR-Z4S, while only rear ABS can be switched off on the DR-Z4SM. They also get a new LCD instrument panel and new LED lighting with a bifunction headlight design.
Wheels and tires differ between the two DR-Z4s. The DR-Z4S includes spoked 21-inch front and 18-inch rear wheels wrapped in IRC GP-410 tube-type tires. The DR-Z4SM comes with spoked 17-inch front and rear wheels fitted with Dunlop SportMax Q5A tube-type tires. Both bikes feature a 240mm rear disc with a single-piston caliper, but their front brakes are different. The DR-Z4S gets a 270mm front disc with 2-piston caliper, while the DR-Z4SM gets a larger 310mm front disc, also with a 2-piston caliper.
Ergonomics are also updated, starting with a new slim fuel tank with a 2.3-gallon capacity. The footpegs are wider, the seat is updated to improve comfort, and the tapered handlebar further enhances the rider triangle. The DR-Z4S has a 36.2-inch seat height and a claimed curb weight of 333 lb, while the DR-Z4SM has a 35.0-inch seat height and weight of 340 lb.
The 2025 Suzuki DR-Z4S will be available in Champion Yellow, Solid Special White, or Solid Iron Gray. The 2025 Suzuki DR-Z4SM will come in Sky Gray or Solid Special White. Pricing has not yet been announced.
