  • Dynamic and versatile design with MAX DNA

    From every angle it's clear that the XMAX 400 has been designed with inspiration from the highly successful new XMAX 300. From the boomerang sidepanels through to the twin front LED headlights and sleek bodywork, this dynamic and versatile scooter is more MAX than ever.

  • Powerful 400-cc, EU4-compliant engine

    The powerful 400-cc engine produces strong acceleration for decisive overtaking and gives you the power to maintain high cruising speeds. You can be confident that the XMAX 400 is one of the most economical and reliable models in the class, thanks to the sophisticated Yamaha engine technology and efficient fuel injection system.

  • Traction Control System (TCS)

    The XMAX 400 comes with one of the highest specifications in the class, and now includes a Traction Control System (TCS) as standard equipment. TCS gives you added levels of confidence and a feeling of safety by preventing the rear tyre from losing traction on slippery surfaces such as wet roads, drain covers, cobblestones and tram rails.

  • Smart Key

    To make life simpler and more convenient there's a Smart Key keyless ignition system. When you're carrying the Smart Key close to you, it enables you to switch on the XMAX 400, unlock the steering and seat, and gain access to the fuel tank and storage compartment. There's also a remote control for locking and locating your scooter with one press of the button.

  • LED lighting

    The front and rear LED lighting system is an integral part of the new design, and helps you to see and be seen. The powerful dual LED headlights project an ultra-bright beam - and because they use less electrical power, the engine runs more efficiently. And to make you even more visible to other road users, front and rear LED guide lights are fitted.

  • Improved underseat storage space

    The XMAX 400 offers one of the biggest storage compartments in the class, capable of accommodating 2 full-face helmets or a large bag - and there's an integral box light for added convenience. Whether you're riding to work in the week or heading to the country for the weekend, this generous carrying capacity always comes in handy.

  • New motorcycle-style front forks

    Just like the iconic TMAX, the XMAX 400 is equipped with motorcycle style telescopic front forks that deliver high-speed stability and increased riding comfort. Together with the dual 267-mm front discs, this high-specification front end gives high levels of control during braking and cornering.

  • New luxury dual seat

    The new high quality dual seat features an independent rider's backrest for added lumbar support, to make the XMAX 400's active and upright riding position even more comfortable. With its understated two-tone cover and double stitched seams, this beautifully finished seat reinforces this class-leading sport scooter's premium look and feel.

  • Ideal balance of style, performance and functionality

    By delivering an ideal balance of style, performance and functionality, the XMAX 400 has the potential to transform every ride. With its premium, sporty specification, high quality and practical features like a parking brake, it is built to make the most of every minute of your precious time – weekdays or weekends.
