Sitting in Yamaha’s range of sports scooter, the updated X-MAX 400 covers the gap between the X-MAX 125 and 300 with the bigger 530cc T-MAX and the Japanese firm has, today, announced the updates the 2018 version.

Available in three colours; Phantom Blue, Sonic Grey and Blazing Grey, the new N-MAX 400 will be available from Autumn and priced below the £6,000 mark, though this will be confirmed at the NEC Motorcycle Live Show.

‘Exciting and stylish’ is Yamaha’s mantra when it comes to their sportier line of twist-and-go machines, essentially to make the most of the commuting. So, with a Euro-4 compliant 395cc, single cylinder, 4-stroke, liquid-cooled, DOHC engine making a maximum power of 32.9bhp at 7,000rpm, Yamaha also have confirmed a weight saving of 5kg over the outgoing model, down to 210kg (wet), thanks mainly to the newly designed lightweight aluminium wheels.

The newly designed dual seat features an independent rider's backrest that gives added lumbar support, and the seat cover's two-tone finish has additional detail such as double stitched seams.

New LED lights adorn the twin headlights and taillight while a newly designed high-tech speedometer that features a pair of classic analogue dials for the tachometer and speedometer with a black background and white digits.

To enhance both steering and rider comfort, the X-MAX 400 comes with motorcycle-style telescopic front forks while traction control now comes as standard.

Many top features remain including keyless ignition, enough underseat storage for two full-face helmets and the 12-V outlet for powering and charging electronic devices that can be stored in the large compartment under the seat when not being used.

Meanwhile, Sport and Touring accessories include exhaust systems, top cases, luggage and a comfort seat.
