MRM NTX99 MT250 Pit Bike – Red

MiniRocket NTX99 MT250 – a hard-hitting two-stroke motocross bike with 32 metric 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 metric 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 build-up and a distinctly sporty character.

The NTX99 MT250 runs on large 21/18" wheels and features hydraulic disc brakes, adjustable twin-chamber FastACE suspension, an aluminium exhaust system, a Gold O-Ring chain and a comprehensive equipment package including CNC-machined aluminium components. This bike is designed for demanding off-road riding, track use, training and fast-paced 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 unit responds more sharply, revs up faster and delivers a noticeably livelier ride. This makes the bike great fun, dynamic and highly responsive to throttle input.

An output of 32 metric horsepower is a very strong figure for this category. The engine is equipped with a balance shaft, which helps reduce vibration and improve running smoothness. With liquid cooling, the engine is better equipped for longer, more demanding rides where maintaining a stable operating temperature is important.

Electric and kick start

A major practical advantage is the combination of an electric starter and a kick start. In everyday use, you can simply start the bike at the push of a button, while a conventional kick-start lever is also available when needed. On a sports 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, 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, with proper maintenance, provides a longer service life.

FastACE twin-chamber suspension

One of this model's greatest 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 stiffness adjustment as well as high-speed and low-speed compression adjustment. 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 roll over uneven ground, hold its line and provide stability 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 pattern, with a more pronounced traction-focused tread on the rear tyre for better grip 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 performance than conventional mechanical brakes. The brake discs are styled to suit sports off-road motorcycles and complement this model's performance-focused character.

The front brake and clutch levers are folding levers that can pivot in several directions. In a fall, they can move 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. The frame is fitted with plastic guards in areas exposed 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 footpegs, CNC-machined fork yokes, an aluminium side stand, an aluminium rear swingarm, a CNC-machined folding gear lever and other details.

The CNC-machined footpegs have a pronounced non-slip profile, helping your boots stay firmly in place 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 track service intervals. Practical USB ports, 1× USB-A and 1× USB-C, can be used to charge a phone, camera or navigation device, for example. Handguards protect your hands from branches, small stones and minor falls.
