MRM NTX99 MT250 Pit Bike – Orange

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

MiniRocket NTX99 MT250 is a full-size off-road motocross bike for riders looking for a light, 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 horsepower. The engine is paired with a manual 6-speed gearbox, and its two-stroke nature gives the bike a very lively throttle response, rapid power delivery 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 more demanding off-road riding, track use, training and spirited riding over rough terrain.

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 responds more sharply, revs up faster and delivers a noticeably livelier riding experience. This makes the bike great fun, dynamic and highly responsive to throttle inputs.

An output of 32 horsepower is particularly strong for this category. The engine features 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 is important.

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 bike at the push of a button, while a conventional kick-start lever is also available when needed. This combination is particularly welcome on a performance off-road bike, providing greater reassurance when out on the trails.

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, allowing the rider to control the power precisely to suit the surface, speed and technical demands of the route.

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

Twin-chamber FastACE suspension

One of this model's greatest strengths is its twin-chamber FastACE suspension. The front end uses twin-chamber forks with adjustable rebound and compression damping. The twin-chamber design gives the suspension a smoother action and helps it cope better with bumps, landings and fast riding over rough ground.

The rear FastACE shock absorber allows adjustment of stiffness as well as high- and low-speed compression damping. Low-speed compression helps when cornering and riding 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 negotiate bumps, hold its line and remain stable at higher speeds.

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

Hydraulic disc brakes

Front and rear hydraulic disc brakes provide 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 performance off-road motorcycles and complement the performance-focused character of this model.

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 guards are fitted to the frame in areas prone to abrasion or damage during off-road riding.

The bike also features a sump guard, 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 plays an important part in the character of a two-stroke engine, contributing to its power, response and the characteristic sound of a performance 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 look. They include aluminium handlebars, aluminium rims, CNC aluminium foot pegs, CNC fork yokes, an aluminium side stand, an aluminium rear swingarm, a CNC folding gear lever and other details.

The CNC foot pegs have a pronounced non-slip profile that helps 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 sockets are also practical, allowing you to charge devices such as a phone, camera or sat nav. Handguards protect your hands from branches, small stones and minor falls.
