The Suzuki AN 400 Burgman, specifically the WVBW generation produced between 2003 and 2006, holds a unique place in motorcycling history. It was the first scooter to successfully bridge the gap between urban commuting and transcontinental touring, effectively standardizing the “Maxi-Scooter” architecture. Unlike its predecessors, the WVBW utilized a link-type rear suspension and fuel injection, which were revolutionary for the mid-displacement scooter segment at the time.

Technical Performance & Engineering

At the heart of the WVBW is a 385cc, liquid-cooled, single-cylinder engine. The transition to fuel injection in 2003 significantly improved cold-start reliability and fuel efficiency compared to earlier carbureted models. The chassis is designed for stability at highway speeds, featuring a long wheelbase that minimizes the twitchiness often associated with smaller scooters.

Maintenance Guide

Lubrication System

For optimal engine longevity, MotoSpecsLab recommends SAE 10W-40 oil meeting JASO MA or MA2 standards. The Burgman’s high-revving nature makes oil quality critical.

  • Oil Change: 1.9 Liters
  • With Filter Change: 2.0 Liters
  • Engine Overhaul: 2.1 Liters

Ignition and Electrical

The WVBW utilizes a dual-electrode NGK CR7EK spark plug. This specific plug is chosen for its ability to provide a consistent spark across a wide temperature range, which is vital for the single-cylinder configuration. The electrical system is supported by a YT12A-BS battery; ensure terminals are clean and tight to prevent the common “click-no-start” issues associated with aging maxi-scooters.

Tires and Safety

Tire pressure is the most influential factor in the Burgman’s handling characteristics.

  • Front (110/90-13): 2.0 bar (29 psi)
  • Rear (130/70-13): 2.25 bar (33 psi) for solo use, increasing to 2.5 bar (36 psi) when carrying a passenger or heavy luggage.

MotoSpecsLab Verdict

The Suzuki AN 400 Burgman (WVBW) remains a benchmark for practical engineering. While newer models offer more electronic rider aids, the 2003-2006 generation provides a mechanical purity and ease of maintenance that appeals to DIY enthusiasts and long-distance commuters alike. Regular attention to the CVT belt and valve clearances is recommended to keep this legendary machine performing at its peak.
