MRM NTX99 MT250 Pit Bike – Blue

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

The 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 horsepower. The engine is paired with a manual 6-speed gearbox, and its two-stroke power delivery gives the bike a very lively throttle response, rapid power delivery and a distinctly sporty character.

The NTX99 MT250 is built around large 21/18" wheels and features hydraulic disc brakes, adjustable twin-chamber FastACE suspension, an aluminium exhaust system, a Gold O-Ring chain and extensive equipment, including CNC-machined aluminium components. This bike is designed for more demanding off-road terrain, track use, 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 more quickly and delivers a noticeably livelier ride. This makes the bike great fun, dynamic and responsive to throttle input.

An output of 32 horsepower is very impressive for this category. The engine is equipped with a balance shaft, which helps reduce vibration and improve smoothness. Thanks to liquid cooling, the engine is better equipped for longer, more demanding rides, when 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. On a sporty off-road bike, this combination is particularly welcome, providing greater reassurance when riding off-road.

Manual 6-speed gearbox

The MiniRocket NTX99 MT250 uses a manual 6-speed gearbox tuned 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, with proper maintenance, provides a longer service life.

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 gives the suspension a smoother action and helps it cope better with bumps, landings and fast riding over rough ground.

The FastACE rear shock offers adjustable stiffness as well as high- and low-speed compression damping adjustment. Low-speed compression damping helps when cornering and riding over smaller bumps, while high-speed compression damping is important for jumps, harder landings and more aggressive riding. This allows riders 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 tackle uneven ground, hold its line and provide stability at higher speeds.

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

Hydraulic disc brakes

Hydraulic disc brakes at the front and rear 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 sporty off-road motorcycles and complement this model's performance-focused character.

The front brake and clutch levers are folding, with movement in several directions. 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 are fitted in areas that may be subject 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 distinctive sound associated with a sporty two-stroke.

CNC-machined aluminium components

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

The CNC-machined foot pegs have a pronounced non-slip design that gives boots a better grip, 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. Riders 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.

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