At its launch, the Suzuki AN 650 Burgman redefined the maxi-scooter category by being the first production scooter to utilize the SECVT (Suzuki Electronically-controlled Continuously Variable Transmission). Unlike traditional centrifugal CVTs, the SECVT uses an electric motor to adjust the pulley diameter, allowing for a unique ‘Manual’ shift mode and a ‘Power’ mode that mimics the engine braking and gear-selection feel of a conventional motorcycle.
Technical Engineering Overview
The WVBU/A chassis houses a 638cc liquid-cooled parallel-twin engine. This powerplant is uniquely positioned low in the frame to optimize the center of gravity, a design choice that provides the Burgman with high-speed stability comparable to dedicated touring motorcycles. The inclusion of an Anti-lock Braking System (ABS) as a standard or optional feature (depending on the specific year and market) further cemented its status as a premium long-distance commuter.
Maintenance Guide & Fluid Specifications
For the longevity of the SECVT and the high-output twin engine, adhering to strict fluid intervals is mandatory. The engine requires 2.9 Liters of 10W-40 oil. It is critical to use oil that meets the JASO MA standard to ensure proper lubrication of the internal components and the integrated transmission systems.
Ignition and Electrical System
The electrical system relies on the robust YTX14-BS battery. Given the electronic complexity of the SECVT and the ABS pump, maintaining a healthy voltage is paramount; a failing battery often manifests as transmission error codes before the engine fails to crank. Spark delivery is handled by NGK CR8E plugs, which should be inspected for carbon fouling every 12,000 km.
Wheel and Tire Management
The Burgman 650 utilizes a 15-inch front and 14-inch rear radial tire configuration. Handling is highly sensitive to pressure changes. For optimal performance and tire life, maintain the front at 2.25 bar (33 psi). The rear requires 2.50 bar (36 psi) for solo operation, but must be increased to 2.80 bar (41 psi) when carrying a passenger or heavy luggage to prevent sidewall overheating.
Frequently Asked Questions
Q: How often should the SECVT belt be replaced?
A: While the belt is designed for long-term durability, it should be inspected according to the factory service manual, typically around the 25,000-mile (40,000 km) mark for wear or damage.
Q: Can I use automotive 10W-40 oil?
A: No. It is vital to use oil with the JASO MA certification to ensure the additives are compatible with the motorcycle’s internal mechanical requirements.
