Introduction
The Suzuki Burgman 400 is a full-size premium maxi-scooter powered by a refined 399 cc liquid-cooled single-cylinder engine that produces 29 PS and 35.2 Nm of torque. With its large fairing, tall windscreen and stable chassis, it is capable of holding high speeds comfortably on the highway. In real-world conditions the Burgman 400 settles between 140 and 148 kmph on GPS. Under ideal conditions the speedometer can climb to 155 kmph. This article explains exactly what those numbers mean and what owners can realistically expect.
Claimed vs Real-World Top Speed
Independent tests and owner GPS data give a clear picture: • Typical real-world GPS top speed: 140–148 kmph • Speedometer reading in normal conditions: 145–152 kmph • Best-case indicated top speed: 155 kmph Most GPS runs on flat roads with a normal-weight rider settle around 140–148 kmph. The speedometer over-reads by roughly 5–7 kmph. That is why the needle can show 155 kmph while true GPS speed remains a few kmph lower.
Best-Case Higher Readings – When It Happens
Seeing 155 kmph on the speedometer is possible but needs near-perfect conditions. These factors help: • Light rider (under 75 kg) • Fully tucked riding position behind the tall windscreen • Slight downhill or strong tail wind • Fully warmed engine and correct tyre pressures • Long, clean straight with no traffic • Stock exhaust and well-maintained drivetrain Under these conditions the engine can push the speedometer needle to 155 kmph. GPS speed in the same run usually stays in the 148–152 kmph range.
Power Specs and Everyday Performance
The Burgman 400 uses a 399 cc liquid-cooled, DOHC, single-cylinder engine producing 29 PS at 6300 rpm and 35.2 Nm of torque at 4900 rpm. It is paired with a smooth automatic CVT transmission. • 0–60 kmph: around 4.5–5.5 seconds • 0–100 kmph: around 10–12 seconds • Comfortable highway cruising: 100–120 kmph • Absolute top end: 140–148 kmph (GPS) / up to 155 kmph indicated The large fairing and tall screen make sustained high-speed cruising very comfortable. Most owners spend their time between 80 and 120 kmph where the scooter feels relaxed and stable.
Final Take
The Suzuki Burgman 400 delivers a real-world GPS top speed of 140–148 kmph. In the best possible conditions the speedometer can touch 155 kmph. That is strong performance for a comfort-focused 400 cc maxi-scooter. The Burgman 400 prioritises stability, wind protection and everyday usability while still offering respectable top-end capability when conditions allow.
