A genuine V-twin moped is a rare sight. Hyosung GV125X Roadster now on sale!

A full-scale cruiser equipped with a V-twin engine appears in the 200cc class.

The GV125X Roadster is a new cruiser model with an urban style that stands out in the city. The water-cooled 125cc V-twin engine that is mounted on the already-released GV125S Bobber model has been fine-tuned specifically for the X and is mounted on a newly designed chassis that pursues sporty riding performance.

Despite its easy-to-handle displacement, it has a design that satisfies the sense of ownership and the appeal of a high-quality pulsating feel that only a V-twin can offer. It is a new style cruiser that has a presence and performance that exceeds that of a 125cc, providing the “fun of riding” and “joy of ownership,” making it the perfect choice for riders who are just starting out in motorcycle life.

Improved performance of the water-cooled 60-degree V-twin engine

The water-cooled 60-degree V-twin engine, tuned exclusively for the X, is based on the conventional model but has increased maximum power and torque. It produces a maximum power of 14.0ps and a maximum torque of 10.7Nm, realizing torque generation at a lower rotational speed than before.

The transmission has been upgraded from 5 to 6 speeds, significantly improving acceleration and cruising performance, allowing for relaxed cruising at high speeds.

Dual exhaust muffler and belt drive

The combined exhaust pipes, which have equal lengths from the front and rear cylinders, pass through a chamber located at the front to ensure minimum ground clearance and are connected to the dual exhaust mufflers on the left and right. This not only achieves both exhaust efficiency and environmental friendliness, but also creates a mechanical beauty and a strong presence.

A belt drive has been newly adopted. It produces less noise than a chain and does not require lubrication maintenance. It also has the advantages of high durability and a long life, realizing a high-quality ride befitting a premium cruiser.

Adopting a modern urban style

Sharp, edgy body design

This modern urban-style cruiser features edgy body parts that create a sharp and dynamic silhouette. The red stitching on the seat upholstery is effectively placed as a sporty accent.

The front footrests are mid-control type, allowing for a relaxed position typical of a cruiser, while the rear ones are smart push-type retractable, combining practicality with a stylish design.

Inverted forks and ABS as standard equipment

The front forks are highly rigid φ41mm inverted type, and the disc brakes are equipped with reliable ABS as standard. The wheels have a luxurious machined finish and are a combination of 16-inch front and 15-inch rear.

The front brakes are a 270mm single disc with an opposed 4-pot caliper, and the rear brakes are a 250mm single disc with an opposed 2-pot caliper. ABS is standard on both wheels.

Full electrical equipment and usability

Full LCD meter with pointer

The LCD meter mainly features an analog tachometer with easy-to-read layout for information such as gear position. The ignition key is located at the front end of the fuel tank so as not to interfere with steering.

All lights are LED type. The distinctive tail lamp is laid out along the end of the rear cowl, giving it a sharp impression and highlighting its presence as a “bike to be seen on.”

USB power port included as standard

A USB power port (Type-A), convenient for charging smartphones and using navigation systems, is fitted as standard on the front right hand side of the fuel tank, making it easy to wire. It can be said to be an essential piece of equipment for modern motorcycle life.

The GV125X Roadster will have a manufacturer’s suggested retail price of 682,000 yen (620,000 yen excluding consumption tax) and will be available in one color, Night Black. It is scheduled to be released in early July 2025.
