The MX50 IMR Replica KTM Pit Bike

This 50cc motocross bike adopts the style of the KTM range under IMR license. It is designed for beginner riders aged 7 and up, with a chassis and equipment tailored for progressive use on natural terrain.

A chassis designed for off-road

The frame is tubular, featuring an upside-down hydraulic front fork and a rear shock absorber with 270 mm of travel. The wheels are aluminum, 14 inches at the front and 12 inches at the rear, fitted with knobby tires for natural terrain. Braking is hydraulic on both wheels. The handlebar is made of 22 mm aluminum.

For which rider size?

The manufacturer recommends this bike for riders aged 7 and up. The seat height is 690 mm, with a dry weight of 41 kg. The maximum load capacity is stated as 150 kg, which reflects the structural strength of the chassis and not suitability for adult use: the recommended age and seat height should guide the choice, not this figure alone.

Controlled use on suitable terrain

The manufacturer states a top speed of 75 km/h. This is a high speed for a vehicle intended for young riders: we recommend gradual learning on a private, enclosed off-road track, under constant adult supervision, and with full protective gear. This bike is not road-legal and cannot be used on public roads.

What is the recommended minimum age?
The manufacturer recommends this motocross bike for riders aged 7 and up. Beyond age, the seat height (690 mm) and achievable speed (stated 75 km/h) require progressive learning and constant adult supervision.
Isn't 75 km/h too fast for a child?
This is the maximum speed stated by the manufacturer, not a typical riding speed. We recommend restricting initial sessions to low speeds on flat, clear terrain with an adult present at all times, before considering faster use.
Is this bike road-legal?
No. It is designed exclusively for use on private, enclosed off-road areas, such as a motocross track or private property with the owner's permission.
Do you need a license to ride it?
No license is required on private, enclosed off-road terrain. The bike must never be used on public roads, including paths or parking areas accessible to other vehicles.
Is the gearbox automatic or manual?
Automatic. There is no clutch lever to manage, which simplifies handling for beginner riders.
How does the engine start?
With a kick starter. The bike does not have an electric starter or a starter battery.
What weight can this bike support?
The manufacturer states a maximum load of 150 kg. This figure reflects the chassis strength and does not mean the bike is suitable for adult riders: seat height and recommended age (7 years) remain the key criteria for selection.
On what terrain can it be ridden?
The wheels, fitted with 14-inch front and 12-inch rear knobby tires, are designed for loose or rough natural terrain such as dirt, grass, or trails. It is not a machine for asphalt.
What maintenance does a 2-stroke engine require?
A 2-stroke engine runs on a fuel/oil mix, with the exact ratio specified in the manufacturer's manual. We recommend regularly checking chain tension, brake pad condition, and tire pressure before each use. The manufacturer does not provide specific maintenance intervals for this model.
What protective gear is recommended?
We recommend a full-face helmet compliant with the current ECE 22.06 standard, certified gloves, clothing with back, elbow, and knee protection, and high boots covering the ankles. This equipment is available in our Gear section.

Warning

This motocross bike is prohibited for use on public roads. It must only be used on suitable terrain: a track or private, enclosed off-road area.
The rider must wear appropriate protective gear and be under constant adult supervision.
Purchase of such a vehicle by a minor over 14 must be made under the responsibility of an adult. Only one rider should be on the vehicle at a time.
Purchases on the XtremRS website must be made by an adult.
Warning: this is a motorized vehicle, not a toy.
It is recommended to have the bike assembled and maintained by a professional, and to check its condition before and after each use.
