Finally, the 2011 400's are being advertised...
http://www.suzukicycles.com/Product%20Lines/Cycles/Products/Burgman%20400/2011/AN400A.aspx?category=scootersLooks like non-ABS isn't available and aside from that, looks like the 2007-09 models. So, at least there will be parts availability across those models for quite some time.

Burgman 400 ABS
MSRP $7,499
Key Features
New for 2011: The Burgman 400 is now equipped with Antilock Brake System (ABS*), which monitors wheel speed, and matches stopping power to available traction.
The Burgman 400 matches its sporty looks and aggressively styled bodywork with all the convenience features of a scooter.
Engine Features
The Burgman comes with a 400cc, 4-stroke, single-cylinder, liquid-cooled, DOHC, fuel-injected engine that was designed to produce broad, useable power with quiet operation and low maintenance.
An Idle Speed Control (ISC) system ensures optimal idling under various conditions.
A convenient electric starting system with maintenance-free battery helps provide quick and easy starts.
Key Features
A belt-drive, CVT transmission is fully automatic and easy-to-use.
Chassis Features
A high-tensile steel-tube frame was designed with strength and rigidity in mind.
Cut-away footboards allow stop-start legwork without uncomfortable stretching.
The Burgman 400 is equipped with a 13.5-liter fuel tank, so it can be enjoyed over long distances between fuel stops.
A stepped dual seat provides comfort and confidence. The rider’s backrest is adjustable in five 10mm increments at the press of a lever.
The Burgman comes with telescopic 41mm inner-tube front forks with a generous 110mm of wheel travel. A motorcycle-style link-type monoshock rear suspension offers adjustable preload. The overall benefits are motorcycle levels of handling and exceptional maneuverability.
14-inch front wheel carries 260mm hydraulic dual disc brake, while the rear wheel has a 210mm hydraulic disc brake for reliable control.
The Burgman 400 is equipped with a convenient parking brake with easy-to-use single lever operation.
Utility/Convenience Features
The Burgman 400 offers abundant luggage space; huge 62-liter storage bay, large enough for two normal size full-face helmets or A3-size document case, and a smaller compartment for small personal items. Convenient switchable underseat lights illuminate the entire underseat area.
Front bodywork contains three lidded storage compartments; a large 10-liter compartment and two smaller compartments above it. A convenient DC power outlet is on board for charging electric devices while on the move.
The comprehensive and easy-to-read instrument binnacle incorporates a speedometer, a tachometer, an odometer, twin tripmeters, a clock, and indicators for the ambient temperature, average fuel consumption, fuel level, and coolant temperature.
A security gate allows a chain lock to be passed through the bodywork around the frame.
*ABS is a supplemental device for brake operation, not a device for shortening stopping distance. Always remember to reduce speed sufficiently before approaching curves and corners.
