EU4-compliant liquid-cooled 155cc engine

The NMAX 155's EU4-compliant engine has been developed using Yamaha's advanced Blue Core technology. This innovative design approach focuses on increasing combustion and cooling efficiency while at the same time reducing power losses, to give you quicker acceleration with a higher top speed and reduced fuel consumption.

Dynamic and sporty body design

The sporty look and premium design of the sleek bodywork has been influenced strongly by our Sport Scooters. Its beautifully integrated tail end gives the NMAX 155 a sporty and sophisticated look - while the boomerang side motifs and central tunnel underline its strong Yamaha MAX heritage.

Variable valve actuation for powerful acceleration

A key feature that makes the NMAX 155 such a sporty performer is its variable valve actuation (VVA) system. The 4-valve cylinder head uses a special camshaft that enables the engine to operate more efficiently at low and high engine speeds, giving stronger acceleration in all rev ranges, together with good fuel economy.

Compact yet roomy

The compact NMAX 155 will fit into the tightest parking area - and yet while being small on the outside, you'll find the interior surprisingly spacious - with generous rider legroom and plenty of space for your passenger. The long stepped dual seat is designed to ensure high levels of comfort - and there's a storage compartment for a full-face helmet.
