The Strengths

  • Modernized electronic fuel injection with 42mm throttle body solves high-altitude cold starting
  • Fully adjustable 48mm inverted KYB forks and piggyback rear monoshock with 280mm/296mm travel
  • Advanced rider aids: 3-level traction control with off-road Gravel mode and switchable ABS
  • Suzuki Clutch Assist System (SCAS) provides light clutch pull and prevents rear wheel chatter
  • Robust twin-spar steel frame with aluminum subframe for heavy luggage and off-road durability

The Compromises

  • Retains a 5-speed gearbox rather than a 6th overdrive gear for high-speed highway cruising
  • Modest 8.7-liter fuel tank capacity limits extended remote desert expeditions without auxiliary fuel
  • 36.2-inch (920mm) seat height requires confident footing for shorter riders in technical terrain

Suzuki DR-Z4S (2026): 398cc EFI Engine, KYB Suspension & Dual-Sport Review

For over two decades, the Suzuki DR-Z400S stood as the benchmark for bulletproof dual-sport motorcycles. The 2026 Suzuki DR-Z4S arrives as a completely overhauled platform designed for contemporary emissions and trail performance standards. Compare competition enduro alternatives in our Kove 450 Rally Review and examine middleweight adventure tourers in our CFMOTO 800MT-X Review.

1. 398cc DOHC Engine: Fuel Injection, Twin-Spark Head & SCAS Clutch

The 398cc liquid-cooled single-cylinder receives an overhaul featuring a 42mm electronic ride-by-wire throttle body, twin-spark cylinder head, and optimized intake cam profiles. Generating 38.0 HP at 8,000 RPM and 37.0 Nm of torque at 6,500 RPM, it provides linear low-end grunt for rocky ascents. The Suzuki Clutch Assist System (SCAS) reduces lever pull force while preventing rear-wheel chatter during aggressive downshifts.

2. Suzuki Intelligent Ride System (S.I.R.S.): Off-Road Traction & Switchable ABS

A standout addition to the DR-Z4S is the electronics package. Riders can select from three SDMS throttle response modes (Active, Basic, Comfort) and four STCS traction control settings. The dedicated 'Gravel' mode allows controlled rear-wheel wheelspin to drive through loose dirt while preventing sudden high-sides. The Bosch ABS system features three configurations: full road ABS, rear-wheel ABS disengaged, and complete dual-wheel ABS disengagement for steep off-road descents.

3. Fully Adjustable 48mm KYB Suspension & Off-Road Chassis Dynamics

Chassis geometry centers around a twin-spar steel frame paired with an aluminum subframe and swingarm. Suspension is handled by 48mm inverted KYB cartridge front forks with 280mm (11.0 in) of travel and a link-type piggyback rear monoshock delivering 296mm (11.6 in) of travel. With 300mm of ground clearance and spoked 21/18-inch wheels, the DR-Z4S handles deep ruts, whoops, and rock gardens with composure.
