MRM NTX99 MT250 Pit Bike – Yellow

MiniRocket NTX99 MT250 – a high-performance two-stroke motocross bike with 32 hp

MiniRocket NTX99 MT250 is a full-size off-road motocross bike for riders looking for a lightweight, powerful and aggressive vehicle with genuine two-stroke character. At its heart is a liquid-cooled LONCIN MT250 2T engine with a displacement of 224 cm³, delivering 32 hp. The engine is paired with a manual 6-speed gearbox, and its two-stroke power delivery gives the bike a lively throttle response, rapid power build-up and a distinctly sporty character.

The NTX99 MT250 features large 21/18" wheels, hydraulic disc brakes, adjustable twin-chamber FastACE suspension, an aluminium exhaust system, a Gold O-Ring chain and an extensive equipment package including CNC aluminium components. This bike is designed for demanding off-road terrain, tracks, training and fast-paced off-road riding.

Genuine two-stroke character

The main difference compared with conventional four-stroke pit bikes and motocross models lies in the engine. The MT250 two-stroke engine has a sharper response, revs up faster and delivers a noticeably livelier ride. This makes the bike engaging, dynamic and responsive to throttle inputs.

An output of 32 hp is a very strong figure for this category. The engine is equipped with a balancer shaft, which helps reduce vibration and improve smoothness. Thanks to liquid cooling, the engine is better equipped for longer, more demanding rides where maintaining a stable operating temperature matters.

Electric start and kick-start

A major practical advantage is the combination of an electric starter and a kick-start. For everyday use, simply start the engine at the push of a button, with a conventional kick-start lever also available when needed. On a sporty off-road bike, this combination is particularly useful, giving you greater confidence when riding off-road.

Manual 6-speed gearbox

The MiniRocket NTX99 MT250 uses a manual 6-speed gearbox set up for sporty off-road riding. The bike delivers lively performance in every gear and allows the rider to control the power precisely according to the surface, speed and technical demands of the route.

Power is transmitted to the rear wheel through a durable chain drive with a 520H Gold O-Ring chain. This type of chain is suitable for more demanding use, offers better resistance to dirt and provides a longer service life when properly maintained.

FastACE twin-chamber suspension

One of this model's main strengths is its FastACE twin-chamber suspension. At the front, twin-chamber forks offer adjustable rebound and compression damping. The twin-chamber design provides smoother suspension action and handles bumps, landings and fast riding over rough ground more effectively.

The rear FastACE shock absorber offers adjustable stiffness as well as high- and low-speed compression adjustment. Low-speed compression helps when cornering and over smaller bumps, while high-speed compression is important for jumps, harder landings and more aggressive riding. This allows the rider to tailor the suspension more closely to their weight, riding style and terrain.

21/18" wheels and MARIEV tyres

The MiniRocket NTX99 MT250 is fitted with large wheels: 21" at the front and 18" at the rear. This combination is typical of adult off-road motorcycles and helps the bike roll over uneven ground, hold its line and remain stable at higher speeds.

The reinforced aluminium rims are fitted with rim locks, which help prevent unwanted tyre slippage on the rim when riding at lower pressures. The bike uses MARIEV off-road tyres, with a more pronounced tread pattern on the rear tyre for better traction on softer ground.

Hydraulic disc brakes

Front and rear hydraulic disc brakes take care of safe stopping. The hydraulic system offers better modulation and more assured braking than conventional mechanical brakes. The brake discs are designed in the style of sporty off-road motorcycles and complement this model's performance-focused character.

The front brake and clutch levers are multi-directional folding levers. In a fall, they can pivot downwards, upwards or away from the handlebars, reducing the risk of breakage.

Durable frame and protective components

The bike is built around a strong steel frame, designed for a load of around 140 kg. Plastic frame guards protect areas that may be exposed to abrasion or damage during off-road riding.

The bike is also equipped with an engine bash plate, a front brake disc guard, an aluminium rear disc guard, an aluminium front sprocket cover and a practical recovery strap for pulling the bike out of mud or difficult terrain.

Aluminium exhaust system

The two-stroke engine is complemented by a distinctive exhaust system with a stainless steel expansion chamber and an aluminium silencer. The exhaust is an important part of a two-stroke engine's character, contributing to its power, response and the characteristic sound of a sporty two-stroke.

CNC aluminium components

The MiniRocket NTX99 MT250 uses a range of aluminium and CNC-machined components. These parts help reduce weight, improve durability and give the bike a more premium appearance. They include aluminium handlebars, aluminium rims, CNC aluminium footpegs, CNC fork yokes, an aluminium side stand, an aluminium rear swingarm, a CNC folding gear lever and other details.

The CNC footpegs have a pronounced non-slip profile to help keep your boots firmly in place, even when riding standing up, in mud or with a more aggressive riding style.

Ergonomics and practical equipment

The long seat provides plenty of room to shift your weight. The rider can move forwards when cornering or backwards on climbs and during faster riding. This makes the bike feel more natural to handle and gives the rider better control over its behaviour.

The equipment includes an hour meter to help keep track of service intervals. The 1× USB-A and 1× USB-C ports are another practical feature, allowing you to charge a phone, camera or navigation device, for example. Handguards protect your hands from branches, small stones and minor falls.
