The Chinese two-wheeled motorized vehicle "Omax-250" belongs to the category of full-fledged light sports motorcycles. The bike's power unit is liquid cooled, a four-valve twin-shaft head, a stabilizer shaft, and a six-speed gearbox. The motor is a prototype of the famous Honda AX-1 (NX250) model. At eight thousand revolutions, the engine output has 25.8 horsepower. The installation volume is just over 250 cubic centimeters. Piston diameter – 71.5 mm. Due to the extreme compactness of the engine, it does not have a kick starter, but this is no longer uncommon on modern bikes.
Description
The Chinese motorcycle "Omax-250" is distinguished by a high level of reliability of starter elements and batteries. The service life of these parts is at least 2-3 years. A small disadvantage of the power unit is the carburetor configuration, which does not have an accelerator pump. At the same time, this practically does not affect the dynamics. The bike's speed limit is 170 km/h, which allows you to fully realize the engine's potential.
The front brake assembly is a pair of discs with radial calipers and reinforced hoses. The design also includes an inverted fork with hydraulic compression control. The steering column is made in the form of clip-ons, the plastic cylindrical reservoir for brake fluid is made in a traditionally sporty style.
Frame
The frame is very flimsy, unreliable, all crooked with broken geometry and welded from such thin profiles that could only probably be found on sale... And according to my feelings, it was welded without the use of a slipway, “by eye”... The “quality” of the welds is simply disgusting , traces of rough grinding with a grinder are visible everywhere, and besides, all this junk is poorly painted. After a year of use, the frame burst in several places and became covered with a fair layer of rust; the owner had to re-weld and paint it.
Admire the “quality” of the welds.
"Omax-250": technical characteristics
There are several popular modifications of the motorcycle in question. Let's study the parameters and differences between them. Let's start with the 250 CC (R11):
- Engine type is a gasoline engine with one cylinder, four strokes, 4 valves per cylinder, and has a liquid cooling system.
- The volume of the power unit is 250 cubic meters. cm.

The Omax-250 SS motorcycle package also includes an instrument panel, rear footrests, direction indicators, and mirrors.
Modifications and competitors
Despite the fact that the motorcycle was developed as a sport-tourer, air cooling forced us to reconsider the class.
ABM GX 250 R
But the producers decided to make a knight's move. A brother appears on the market - ABM GX 250 R. Improved version. She gets:
- liquid cooling;
The cooling system radiator is located in a standard place behind the front fork stays.
All in all, this resulted in an increase in driving parameters. Maximum speed 130 km/h , overtaking up to 150 km/h , cruiser 120 km/h . Acceleration dynamics have also increased. Fuel consumption remained unchanged - according to reviews, the average is 3.8 liters .
Other manufacturers
There are 4 models listed as competitors for the motorcycle. This:
- Motoland X6 250 . It develops 120 km, has 18 horses , direct flow.
- Nitro 200 . Not much different. But bifurcated exhaust, engine protection, LEDs. Due to the smaller engine volume, only 16 horses were driven under the hood.
- Pegas Skyway 250 . It stands out from a number of competitors with an adjustable gas-oil fork and 2-disc brakes . Among the goodies - a pre-installed alarm system, LEDs, and a balancing shaft. There are 19.5 horses under the hood .
- Regulmoto T-Leopard 250 . It is mistakenly called a pit bike, although according to its characteristics it belongs to motorcycles. Its stock features are amazing - 6 mortar, water cooling, music and alarm. Under the hood there are 24 horses , and the maximum speed is 160 km/h .
All bikes have 1 cylinder, 5-speed gearbox, comparable engine capacity, and a full set of lighting equipment.
Recently, the Wels Ghost 250 . It offers the buyer a 5-speed, LEDs, 17 horses , hydraulic suspension. Engine 1 cylinder, 4 strokes.
SK250 X6
This modification in Europe is also known under the name Romet Division 249. The model differs from its “brothers” in multi-spoke wheels, a triangular, ergonomic, shortened muffler, and falls into the “naked” category.
"Omax-250 X6" is equipped with a central stand, original LED indicators and a taillight. The instrument panel includes a dial tachometer, a liquid crystal display that displays speed parameters, remaining fuel, mileage, time and active gear number. The seats are removable and can be removed by turning a key and a latch. There is a storage compartment under the driver's seat for tools and small accessories.
The power unit is equipped with a two-valve atmospheric design, made according to the ONS scheme. This approach made it possible to increase power and maximum speed. The exhaust system consists of a pair of pipes, although the engine has only one cylinder. The power plant is equipped with a balancing mechanism, which reduces vibration at high speeds, the limit of which is 130 km/h. For more correct operation of the device, it is advisable to accelerate it to the maximum after running it for at least a thousand kilometers. The gearbox has five ranges, the speeds change smoothly and with reasonable lever travel.
Suspension
The front wheel suspension is independent, two-link type, not made reliably, but quite well and of high quality. I was especially pleased with the powerful ball joints; most likely they were borrowed from some car or ATV of a heavier class.
The front suspension works roughly and instead of softening the unevenness of the road, it does the opposite - it throws the ATV up on bumps. It is not clear why they stuck it here then, if it does not fulfill its function. For beauty or what?..
The front wheel brakes are drum brakes with a cable drive, which also have a bunch of adjustment elements inherent in all brake systems with a cable drive.
After two hours of adjustments, I still could not somehow get these brakes to work. So I left it, left it as it was... And it was without working front brakes.
The rear suspension is dependent, pendulum with a central monoshock absorber with stepwise adjustment of the spring preload. The workmanship of the rear suspension elements is simply disgusting, unlike the front one. The entire design is based on two flimsy tubes; besides, all this junk is welded poorly and with obvious distortion.
The chain tension adjustment built into the rear swingarm does not work properly. I was never able to somehow tighten the slightly stretched chain. The adjustment grooves in which the tension mechanism rotates are too short and do not allow the chain to be tensioned. I tried to shorten the chain - the effect was the same: when moving back, the bolts hit the adjustment grooves and did not allow the lock to be fastened on the chain. Keep this point in mind: the chain tension here is adjustable within an extremely limited range, so if the chain stretches the slightest, you will have to replace it with a new one.
The second unpleasant moment is associated with adjusting the chain tension: after unscrewing the bolts of the tension mechanism, the rear wheels become skewed by the front ones and they have to be somehow aligned with the front wheels using a tape measure. And besides, this has to be done simultaneously with adjusting the chain tension. Let me tell you, it’s still a lot of work...
But the rear suspension works well, but still, as for me, it is rather weak on large bumps and breaks through. The rear disc brakes perform their function, the ATV settles well, there are no complaints about their performance and quality. Proper protection of the brake disc and drive sprocket is already present in the basic configuration.

Owner reviews
Users note the reliability of the sports bike in question, despite its Chinese origin. Along with the reasonable price, consumers are pleased with the dynamics and original appearance, although it is unlikely to be suitable for experienced racers. Some owners complain about the rapid wear of the cylinder and tires, as well as the low speed by the standards of sports two-wheeled vehicles. Nevertheless, getting spare parts for the Omax-250 will not be a particular problem, unlike its Japanese counterparts. In addition, “Japanese” ones cost 2-3 times more.
As evidenced by practice and feedback from owners, it is better to buy a motorcycle of the brand in question from official dealers who provide a warranty and service. In general, for its price category, the Chinese sports bike looks pretty good and behaves confidently on the road, giving the rider pleasure when moving on asphalt and other types of trails.
Advantages
The ABM GX 250 is one of the many small-capacity bikes from the Middle Kingdom that literally flooded the lower-priced segment of the motorcycle market.
There are also advantages:
- Frisky . As for a Chinese, the maximum speed is normal. But if you change the stars, the acceleration dynamics can also be improved.
- Powerful . Having a small engine capacity, the motorcycle allows you to shoot between rows without losing speed when changing the throttle.
- Reliable . Single cylinder, air cooled, chain. There is simply nothing to break, and if problems arise, the nearest store has everything you need.
- Beautiful appearance . Although it’s not a sport in terms of performance characteristics, it’s a design!!
- They ask “how much did you get it for?” Girls are often attracted to “real” sports.
- Headlight . It’s a rare case for a Chinese when one 2-helix works well in both high and low beam.
The irregularly shaped headlight is embedded in the plastic of the wind fairing.
Despite the sporty positioning, the full-size 2-seater saddle will allow you to ride with a passenger.
There are handles behind the passenger seat; there is no stock trunk.
