The Stealth Tactic 50 scooter did not shine with impressive technical characteristics, catchy design or other advantages even at the moment when it first went on sale. Why did he become so popular? It's simple - dealers offered it at very low price, and this has attracted a large number of thrifty buyers for whom the cost of purchase and maintenance is of paramount importance. Over the past years, tens of thousands of copies of this model have been sold, and many of them are still in use, because there are no problems with spare parts, and budget motorcycles are always relevant.
Technical indicators
The skif 50 model from stels has impressive technical characteristics, which are worth paying attention to before purchasing equipment:
To begin with, it is necessary to note the small size and weight of the scooter, thanks to which women and even teenagers can operate the equipment. The small dimensions of the model allow you to move comfortably and safely in dense city traffic.
The 50 cc two-stroke engine can produce up to 5 hp for the driver. pp., which is quite suitable for novice drivers. A reliable suspension with sufficient travel will not let the scooterist down even when driving on country roads. Disc and drum brakes, which give confidence in control, can balance out the lack of driving skills. Despite the low maximum speed (up to 60 km/h), the scooter has good dynamic performance.
Pros and cons of technology
The skif 50 scooter has both advantages and disadvantages that you need to keep in mind before purchasing. The advantages of the model include:
- High-quality assembly.
- Reliability of the suspension and braking system.
- Low cost (from 20 to 50 thousand rubles depending on mileage).
- Stylish design.
- Spacious luggage compartments.
- The presence of a security alarm as standard.
- Availability and low price of spare parts.
- Good load capacity.
- Comfortable fit.
The scooter also has its disadvantages. For example:
- It is not very convenient for people of great height and impressive build to move around on it.
- Fairly high fuel consumption.
- You come across poorly assembled scooters, which after 6–12 months begin to develop various breakdowns (from failure of the throttle handle to noise from the brakes).
In conclusion, it is worth saying that the Stealth Skif 50 can be a good replacement for more expensive scooters with mileage. However, it’s up to you to decide what to choose – a used Honda Dio or a new skiff.

The principle of operation of ignition in a 4-stroke scooter engine
Modern scooters are equipped with contactless systems. They are considered the most reliable and easy to use, do not require complex connections, and provide a constant good spark on time. However, the setting is still important; even the presence of a spark does not always allow the fuel mixture to ignite, since its power also plays a role.
The main reasons for the operation of the ignition system are quite simple: its task is to create a spark to detonate the fuel mixture. If this does not happen, you need to carefully examine each node and find out why the spark disappeared.
Broken ignition is the cause of engine failure
An incorrectly configured or faulty ignition often causes engine failure. It would be wrong to immediately climb into the cylinder and examine the insides of the scooter, especially since this will not solve the problem. Before touching the ignition system, you need to check for other reasons why the scooter may not work.

- You should wash the scooter yourself only after the engine has completely cooled down. This should be done with a sponge and a special vehicle cleaner. Polishing should be done with polishes that match the color.
The Stels Skif 50 model is highly maneuverable
- Before storing equipment for a long time, you need to thoroughly wash and dry it, fill the tank with gasoline and stabilizer. Then you need to let the engine run for about 10 minutes and drain the fuel from the carburetor. Then disconnect the battery and plug the exhaust pipe with a rag, coat all parts with a wax-based preservative and cover the scooter with a special cover.
- Do not start the engine without connecting the battery properly as this may damage some electrical components.
- For questions regarding warranty and post-warranty repairs and maintenance, please contact the company where you purchased the scooter.
Battery
You should check the electrolyte level in the battery every 1000 km. Exceptions include maintenance-free batteries. On the lid of these it will be written: “DO NOT OPEN”.
To check the battery, you first need to remove it. To do this, you need to open the battery compartment cover and disconnect the positive and negative contacts. Then check the electrolyte level and add distilled water if necessary. When reassembling, the positive contact is connected first, and then the negative one.
Most spare parts can be found in service centers
Wiring
Let's briefly look at the operating features of the Stels Skif 50 CPG. When the engine is running, a large load is placed on the cylinder. Chemical energy is released, but only a small part of it is converted into mechanical work. Most of the remaining heat is removed by cooling air created by the cylinder fins. These fins must be kept clean to avoid thermal insulation of the cylinder, causing the piston and the cylinder itself to become deformed.
In completely new engines, the piston in the cylinder is likely to scuff. For engines that have undergone appropriate tuning, there may be a gap between the cylinder and the piston.
Such clearances are checked during special tests of prototype engines.
The temperature of the piston is not the same during engine operation, so its shape is adjusted solely to avoid various types of deformation. After all, at maximum thermal load the piston expands, but there must be a working gap between it and the cylinder.
At a fairly low and affordable price you can purchase spare parts for Stels Skif 50
In order to check the Stels Skif 50 starter relay, you must first disconnect the red and white motor wire. Next, turn the scooter's ignition switch and squeeze the brake lever. Press the starter button and check the continuity of the circuit; it should not be broken.
Is tuning possible?
Spare parts for Stels Skif 50 can be purchased at a fairly low and affordable price. But without having the appropriate experience, tuning a scooter yourself is not recommended.
It is not recommended to do tuning a scooter with your own hands without the appropriate experience.
The following tuning options are possible:
Design
Externally, the Stels Tactic 50 somehow subtly resembles all the scooters in the world at once, which is clearly visible from the photo. It is completely devoid of any recognizable features, and when creating its appearance, Chinese designers clearly did not bother. Why, they were even too lazy to copy some nice Japanese or European bike! But for this price it will do.
Reviews
Most reviews are extremely favorable. Among them you can see the following advantages of a scooter: fast, reliable, quiet, soft. There are also negative reviews, but, as a rule, they dilute the entire positive review. Most often people complain about high fuel consumption. But this is either a matter of chance or unsuccessful tuning.
The Stels Skif 50 scooter is purchased by both men and women. In the end, everyone is satisfied in the case of normal driving on city roads. It’s not surprising, because this equipment is designed specifically for moving around the city and between populated areas.
Review of the Stels Skif 50 scooter
Stels Skif 50 is a magnificent scooter, created by inventive engineers and combining small size and considerable power. This equipment is perfect for both driving in urban conditions and traveling over rough terrain. Thanks to its compactness, Stealth Skif is indispensable when moving through traffic jams, and its large carrying capacity allows you to go on a picnic on it without worrying about the weight of the products you take with you.
Stels Skif scooters are considered the most interesting, original and unusual among the bikes produced by this company. This is not surprising, because their characteristics are truly remarkable.
So, this bike is equipped with a “fifty dollar” - a two-stroke engine, the volume of which is 50 cubic centimeters. It is equipped with one cylinder. The engine is air cooled and has electronic ignition.
The Stels Skif 50 has three types of starting the “heart”: remote (carried out using a key fob), electric and using a kick starter.
The engine has quite good data - its power reaches five horsepower, and its torque is 3400 rpm.
The transmission is mechanical, the front gear is continuously variable, there is no rear gear.
Thanks to good shock absorbers, the bike behaves quite well on uneven roads. The hydraulic front suspension consists of two springs, and the rear linkage suspension has one.
The Stels Skif 50 scooter is a two-seater vehicle with rear-wheel drive.
The standard equipment of this vehicle includes the motorcycle itself, mirrors, trunk, alarm and cover.
Now about the parameters. An attentive buyer will certainly be amazed at the combination of the data described above with such a small size. So, the scooter weighs only 84 kilograms, which makes it very convenient. The length is slightly more than 1.7 meters, and the height is 113 centimeters. In order for two people to fit on such a baby - a driver and a passenger, the seat is made on two levels.
Gasoline with an octane number of at least 92 is considered optimal, and the recommended oil is 2 tons.
Another undeniable advantage of the Stels Skif 50 scooter is its carrying capacity. This baby is capable of carrying more than 150 kilograms, that is, two average-weight passengers and some additional luggage.
According to owner reviews, Stels Skif 50 is a stylish, comfortable and powerful scooter, perfect for drivers of any gender and age.
Review of the Stels Skif 50 scooter
Scooters up to 50cc, and even those made in China, are in very good demand in Russia, and there are many leaders in this class. One of them is the Stels Skif 50 scooter, which we will review.
The Stealth scooter range has very good options, and most of them are small-capacity, inexpensive models. The Skif model is a standard scooter, ideal for beginner scooter riders, as well as for getting around the city. Among the important differences between the model and other scooters is the large number of luggage compartments. The second advantage is the large seat for two passengers. As for the design of the scooter, the company did an excellent job in this regard, because outwardly the new product can be called sporty. The presence of carbon elements adds style.
Pros:
- Lots of luggage compartments
- Excellent opportunities for cargo transportation
- Low price stealth skiff (from RUR 30,000)
- Good fit
- Possibility to buy a scooter with a security alarm
- Sporty design
Minuses:
- Some models come across as defective
- There were reviews about high fuel consumption
- Not suitable for big and tall people
Broken ignition as a cause of engine failure
First of all, I would like to talk about what can cause a four-stroke scooter engine to fail, and whether misconfigured ignition should be blamed for this. Answering this question, we can answer with one hundred percent confidence that an incorrectly configured or simply faulty ignition may well become the cause of engine failure. However, it is too early to blame everything on a faulty ignition system until you check the main parts that affect the performance of the engine. Let's talk about them in more detail.
The first and perhaps most obvious is a lack of fuel or a clogged carburetor. Before you start trying to adjust the ignition, thoroughly clean the carburetor and make sure that fuel is flowing to the engine. Also, check that the carburetor is providing sufficient air supply.
The second, most common reason why an engine refuses to start is faulty spark plugs. Make sure that the spark plugs used in the scooter are not punctured and have a good enough spark. Simply replacing the spark plugs usually helps.
If you are completely convinced that there are no more reasons for the engine not to start, then you can dig deeper and look for the problem in an incorrectly configured ignition. Let's figure out how to set the ignition on a scooter.
Characteristics of Stealth Skif 50
The details of this scooter are quite standard for a Chinese vehicle. But every model has something of its own. This scooter has improved load capacity and fuel tank capacity. To be more precise, the scooter can be filled with 5.2 liters, and this model can carry a weight of about 140 kg. The dimensions of the scooter are also quite standard - 174, 66, 113 cm. The dry weight of the Stealth Skif 50 is 82 kg. But if you are the owner of this scooter or intend to become one, you will be interested in the engine characteristics in any case.

Buying the Stealth Skif 50 is necessary for those who plan to travel well in the city, because the scooter is not afraid of traffic jams, which are easy to get through due to its small size. They gave the scooter maneuverability and easy controllability. Also, judging by numerous reviews, the scooter can reach a maximum speed of up to 75 km per hour, but only after a complete and high-quality run-in. Another excellent feature of the scooter is the presence of an oil tank and a fuel tank, because this is why the scooter does not smoke, which cannot be said about other Chinese models that need to mix fuel with oil. The stealth skiff scooter, spare parts for which can be found in any store at a low price, can be easily repaired on your own, because this model has a simple 2t engine with quite standard components.
As you can see, judging by the characteristics of the scooter, it can serve you as an excellent vehicle for moving around the city. You don’t have to worry about inconvenient operation; the manufacturers took care of this by making a comfortable seat and plenty of luggage compartments.

What can you buy without having category “A” and not be too embarrassed?!))) I’ll consider these options: Yamaha TZR 50 Aprilia RS 50 Yamasaki Scorpion Honda NS 50 F (AC08)
Approximate price tag for these “MOPEDS”, new used
Yamaha TZR 50 120/60 (for 3 years)
Aprilia RS 50
170/ 60 (for 5 years)
Yamasaki Scorpion
55/ 30 (for a year)
Honda NS 50 F
130/ 70 (for 3 years)
I’ll tell you for myself, I drove 1,2,3 variants... Aprilia and Yamaha are very revvy, allow you to turn up to 12,000, accelerate to 60 km/h quite vigorously! Yamasaki drives his 100 easily, well, everything is clear here))) although the 90 drives, and also, the sound from the can is just garbage, like on a liter one)))
Japanese engineers did their best. Even with a minimum engine capacity of 50 cubic centimeters, this motorcycle is water-cooled, electric starter, separate lubrication, 5-speed gearbox and all disc brakes. Twin headlights, clean lines, perfectly coordinated plastic body kits, all this and much more makes this motorcycle unique in its category. Some people, looking at this bike, cannot believe that it is just a 50 cc moped.
In addition to excellent Japanese build quality, a fairly good selection of components (tires, spark plugs, etc.), the Yamaha TZR 50 motorcycle can easily be improved, adjusted and tuned. In order to save engine life, the new bike has a limit or so-called “cut-off”, so the maximum speed is within 50-60 km/h.
For those people who want to get maximum opportunities and adrenaline, it must be said that this motorcycle can be safely and without any problems “accelerated” to 100 kilometers per hour. Watch various videos on YouTube to prove this.
In addition to a whole “field” of possibilities for tuning, this bike does not require a category “A” driver’s license. You can ride it in Russia without a license (at least for now). All mopeds, scooters and motorcycles up to 50 (49.9) cubic meters do not need to be registered.

Aprilia RS 50 (there were 3 models)
All over the world, 50cc two-wheelers are classified as mopeds, but the Aprilia RS 50, along with a few other motorcycles, manages to fall into the category of sportbikes.
If you start to figure it out, at first it seems like how a little one with a 50 cc can relate to sports bikes. The fact is that the power of a two-stroke engine reaches 8.4 hp. Plus, Aprilia has developed an excellent aluminum chassis, swingarm, lightweight wheels and a beautiful fairing for the bike, which is typical of true sports motorcycles.
Of course, the RS 50 is designed especially for beginners and teenagers. In a month or two you can get used to the bike, which is why Aprilia prudently release an “80cc kit”.
The Italians openly declare that the RS 50 is the leader in the 50 cc sports motorcycle class, and it’s hard to disagree with them. In terms of design, the RS 50 shares many of the features of Aprilia's former flagship, the RSV1000R, the bike that beat the Japanese monsters to win the Master Bike Trophy in 2006.

Honda NS 50 F (AC08) is a real road bike, 50 cc. Let's touch on the design of this device in more detail: the front fork is hydraulic, the rear is a monoshock absorber, the front brakes are two-piston discs, and the rear are drums. The engine is liquid cooled, equipped with a 6-speed gearbox, which works very clearly and while driving you know exactly which gear is engaged. As a rule, all Honda NS50Fs come to us in a converted form, so their speed is about 100 km/h, which is very convenient for driving in city traffic, but still 100-110 km/h is the limit for it, so if you want your Honda NS50F has served for a long time, it is better to cruise 80-85, and accelerate to maximum speed only when overtaking. In terms of acceleration dynamics, the Honda NS50 F is practically in no way inferior to 2-stroke scooters with a capacity of up to 125 cc, so in city traffic and on a country road you will feel like the king of the situation. The suspension of this motorcycle absorbs uneven road surfaces quite well, and the 17-radius alloy wheels give confidence on the road. Honda is strictly a single-seater, although I have also seen converted two-seater versions. Honda NS50F is suitable for beginners to master the skills of driving a motorcycle, and for all those who like to unscrew it completely, but do not have category A. + simplicity and reliability of design, powerful lighting equipment, high maneuverability and excellent controllability, intelligible gearbox, high maximum speed - single-seat model.
