4-valve Loncin YB250R (171FMM)

The modern single-cylinder 4-stroke engine has a displacement of 249.4 cm³ and develops a maximum output of 23.2 hp. The 4-valve cylinder head allows the engine to work efficiently across a wide rpm range and makes it well suited to active off-road riding.

Nibbi PWK32

The Nibbi PWK32 carburetor provides quick throttle response and allows the fuel system to be precisely tuned for different riding conditions and riding styles.

23.2 hp for active off-road riding

The engine provides enough power for forest routes and training as well as more technical off-road riding. The RMX 250A has a strong reserve of torque for climbs, acceleration and difficult terrain.

5-speed manual transmission

The 5-speed gearbox makes it possible to use the engine effectively both on slow technical sections and on faster dirt roads and off-road routes.

520H chain and 46T rear sprocket

The reinforced 520H drive chain works together with a 46-tooth rear sprocket, providing a practical drivetrain setup for enduro use.

Low adjustable 910 mm seat

A 910 mm adjustable seat height makes the RMX 250A more accessible to riders of medium and shorter stature and helps provide more confident control on difficult terrain.

Adjustable front suspension

The 41 mm inverted telescopic fork features a range of adjustments, allowing the front suspension to be adapted to rider weight and track conditions.

Adjustable rear monoshock

The rear suspension uses an adjustable monoshock. This makes it possible to fine-tune the motorcycle for either comfortable trail riding or more active off-road use.

Full-size 21"/18" wheels

The 21-inch front and 18-inch rear aluminum rims provide classic enduro geometry and improve the motorcycle's ability to roll over holes, roots, rocks and other obstacles.

Full LED lighting

The headlight, turn signals and rear light all use LED technology. LED lighting gives the motorcycle a modern appearance and provides good visibility in low-light conditions.

Protection included as standard

The JHL RMX 250A comes standard with engine protection and hand guards, which are especially useful for forest trails and technical off-road riding.

On technical terrain

The compact 1395 mm wheelbase, adjustable suspension and 21"/18" wheels help the RMX 250A remain maneuverable on narrow forest trails, climbs and difficult technical sections.

Power without unnecessary bulk

The 23.2 hp engine provides a serious reserve for active riding, while the mid-size chassis remains easier to control than larger full-size enduro motorcycles.

For riders of medium and shorter stature

The 910 mm adjustable seat height makes it easier to reach the ground and improves motorcycle control at low speeds and on difficult terrain.

Built for skill progression

Adjustable suspension, full-size enduro wheels and a 4-valve engine make the RMX 250A suitable not only for first off-road rides but also for regular training and continued skill development.
