On sale March 21st | New Yamaha NMAX155, an evolved urban sports scooter with an electronically controlled CVT and sophisticated design

Yamaha NMAX155…459,800 yen

The new NMAX155, which Yamaha will release on March 21, 2025, is a particularly noteworthy model among mid-class scooters, available for 459,800 yen (tax included).

This model change sees the adoption of the latest electronically controlled CVT “YECVT (Yamaha Electric Continuously Variable Transmission),” which has significantly improved driving performance and operability. The body has a more refined impression than the previous model, making it a vehicle that combines practicality as an urban commuter with sporty driving.

A new riding experience brought about by the 155cc BLUE CORE engine and YECVT

The NMAX155 is equipped with a water-cooled SOHC 4-valve single-cylinder 155cc engine based on Yamaha’s unique “BLUE CORE” combustion efficiency improvement technology. It is characterized by its powerful low-to-mid speed range and good power output at high speeds, making it easy to handle in any situation.

This engine is mated to the newly introduced YECVT, which differs from conventional continuously variable transmissions (CVTs) in that it electronically controls the timing of gear changes and the effectiveness of engine braking to achieve a more direct driving feel that is closer to human sensations.

On slopes or when acceleration is required, the driver can instantly downshift using the throttle or the shift button on the handlebars, allowing for a rhythmic driving experience similar to that of a manual transmission. On downhill slopes, the engine brake is controlled to work naturally, providing excellent performance in both safety and comfort.

A comfortable riding environment created by a revamped body and equipment

The new NMAX155 has steadily evolved not only in appearance but also in practicality. The body design is tighter, incorporating sharp lines while creating a sense of quality through smooth surface composition. The LED headlights and taillights have also been newly designed, combining visibility and design.

The front end has a structure that maintains light steering while increasing rigidity, achieving both good maneuverability in the city and high straight-line stability. The riding position is natural and fatigue-free, and the seat height is set low at 765mm, making it easy to reach the ground with your feet. There is ample storage space, and there is enough space under the seat to store a full-face helmet. It is also equipped with a 12V power socket, so it can be used to charge smartphones and other devices.

Fully equipped with electronic devices to enhance safety and convenience

The evolution of electronic control is not limited to driving performance. The NMAX155 is equipped with a traction control system that suppresses rear wheel spin even on slippery roads, supporting stable acceleration. ABS (anti-lock braking system) is also standard equipment, enhancing safety during sudden braking.

Furthermore, the adoption of a smart key system makes it possible to start the engine and lock/unlock the vehicle while keeping the key in your pocket, greatly improving everyday convenience.The meter is an LCD display with excellent visibility, and the driving mode, trip meter, fuel consumption information, etc. are organized so that they can be checked at a glance.

The optimal solution for moving freely around the city

The new NMAX155 was born from a design concept that meets both riders who want convenience as a means of commuting and transportation in urban areas and riders who want a sporty riding feel. Going beyond the boundaries of conventional scooters, it achieves a ride that emphasizes a sense of unity with the rider, while its electronic controls and comfortable equipment make it a bike that can be used stress-free even in everyday use.

It is worth noting that not only is it limited to a 155cc engine displacement, but it also boasts a finish that rivals higher-end models in terms of both technology and design, all at this price point. This new model is great for a wide range of situations, from commuting to shopping to weekend touring, and is the ideal scooter that “turns your everyday means of transportation into a hobby.”
