Ergonomic Design & Seat Comfort
The DR650S features a traditional dual sport design with a relatively high seat height of 885 mm (34.8 inches), which can be lowered with an optional kit to 845 mm (33.2 inches) for shorter riders. Its seat is simple but durable, designed for long-lasting comfort over extended rides. The bike’s upright riding position and wide handlebars provide good control and comfort for both on- and off-road use.
The DRZ400 has been redesigned for 2025 with new ergonomics, including a wider, more comfortable seat, aluminum tapered handlebars, and wider footpegs. These changes improve rider comfort and control, especially on technical trails. The suspension is fully adjustable, allowing riders to fine-tune the ride quality to their preference, which enhances comfort over rough terrain. The DRZ400’s seat height is similar but often feels more accommodating due to its ergonomic improvements and lighter weight.
Riding Style
Suzuki DR650S:
This bike excels as a versatile all-rounder. Its larger 644cc air-cooled engine provides strong low-end torque, making it ideal for riders who want a reliable machine for mixed use - from highway cruising to moderate off-road trails. The simpler carbureted engine and basic electronics appeal to riders who prefer mechanical simplicity and ease of maintenance. It suits adventure riders who value ruggedness and straightforward performance over cutting-edge tech.
Suzuki DRZ400:
With a smaller, liquid-cooled 398cc DOHC engine and modern electronic fuel injection, the DR-Z4S is tailored more toward riders who want a nimble, responsive bike with advanced features like ride modes, traction control, and ABS. Its fully adjustable suspension and lighter weight make it better suited for more technical off-road riding, trail riding, and riders who want a more dirt-bike-like experience without sacrificing street legality. It is also good for riders who appreciate modern electronics and smoother throttle response.
Most Common Modifications & Suggestions
DR650S
• Heat Dissipation: The air-cooled DR650S can run hot during slow-speed technical riding or in hot climates. A common modification is upgrading the cooling system with aftermarket oil coolers or enhanced air flow solutions to improve heat dissipation.
• Suspension Upgrades: Many riders replace or upgrade the stock suspension components to handle heavier loads or rougher terrain better.
• Tires and Wheels: Switching to more aggressive off-road tires and adding rim locks (especially for low-pressure sand riding) is popular to prevent pinch flats.
• Exhaust and Intake: Aftermarket exhaust systems and air filters improve performance and sound.
• Electrical Accessories: Despite its simplicity, the DR650S offers accessory wiring points for installing auxiliary lights, GPS, or heated grips.
DRZ400
• Suspension Tuning: The fully adjustable KYB suspension can be fine-tuned or swapped with aftermarket components for specific riding styles.
• Tires: Changing to tires better suited to the rider’s terrain preference (more aggressive off-road or dual-purpose) is common.
• Exhaust: The slim double-wall exhaust can be replaced for weight savings and improved sound/performance.
• Electronics: While the DR-Z4S comes with advanced electronics, some riders would prefer adding aftermarket lighting or navigation aids.
• Clutch and Brake Upgrades: Upgrading clutch and brake components can bring more precise control and handling.
