One of the favorites of the modern domestic motorcycle market is the Chinese sports moped called Alpha. This model has a number of significant advantages. Fans especially appreciate the fact that only two liters of fuel are consumed per hundred kilometers.
Sports version of the Alpha moped
Specifications
Alpha Sport, a stylish black moped made in Asia, is distinguished by the following characteristics:
- engine capacity is 110 cubic centimeters;
- fuel tank volume - 6.5 liters;
- there is an electric starter as a starting system;
- carburetor as a fuel injection system;
- the model is capable of reaching a speed of 100 kilometers per hour;
- the moped weighs no more than 85 kilograms;
- braking system - rear and front brake;
- transmission - mechanical 4-speed;
- shock absorbers - 2 pcs;
- wheel size - 17 inches.
The model is also equipped with a trunk (rear) and an alarm. The engine is air cooled. Additional dynamics are provided by an extremely powerful engine, and a strict sporty exterior - in particular, by creative colors, a compact fairing and reliable black wheels.
Alpha Sport, equipped with everything necessary for a safe and comfortable trip, and capable of withstanding a load of even 120 kg, behaves predictably even off-road. A pleasant bonus is that there is no need to register motorcycle equipment or purchase a driver’s license.
Advantages
Additionally, the model is equipped with special mudguards on the front and rear wheels. These elements allow you not to be afraid of dirty splashes even in the most inclement weather.
Sports Switch
Even such a modernized moped as Alfa Sport needs professional and high-quality tuning. This is necessary to increase speed and dynamics, as well as to improve the performance of the Chinese model.
Not only the cylinder-piston group, but also the commutator has a significant impact on the dynamics and speed.
The sports switch directly affects the speed of the moped
The factory switch assumes 2-5 thousand engine revolutions per minute. This ensures economy and maximum torque efficiency.
The difficulty lies in the fact that at medium and idle speeds the operation of the engine, which often overheats and periodically “shoots” at the carburetor, will not be stable. In order to protect the model from risks, it needs a sports switch. Unfortunately, such a switch is extremely rare on the market today.
Let's summarize the above
First, use a light bulb to check whether the switch generates a pulse or not:
- If the light is on, the switch and the modules that ensure its operation are 100% operational
- If the light does not light, it means that the switch or some module that ensures its operation has failed. And to understand for sure that the switch is faulty, we need to check all the modules.
- If the modules turn out to be serviceable, but the switch does not generate a pulse, then it is faulty and you can safely replace it with a new one
In conclusion, I would like to warn you against the temptation to take a known-good switch from someone and plug it in instead of your own. Yes, with this express method the faulty switch will be identified immediately. If it was really faulty, then with a known good one, a spark will immediately appear.
But how can we be 100% sure that the wiring of the scooter is in perfect order and no one has managed to put their smart personality into it before you?.. What if something shorted or some tusk messed up the wiring in his own way and then the working switch will receive a “complete butt”. And then you will buy two switches - one for the person you asked for, the second for yourself. Do you need it?
Meaning
The main reason for buying a “sports” switch is the thirst for freebies. Many people mistakenly believe that since the switch says “sports”, then putting it on a scooter will immediately add several hundred rubles to the merchant’s pocket three times in power and a couple of times in maximum speed. Yeah, we were daydreaming.
Freebies in matters of tuning DO NOT EXIST AND NEVER EXISTED! Normal tuning costs a lot of money: if you charge an ordinary “Chinese” on average, then this pleasure will cost at least 35,000 rubles. Yes, it’s more expensive than buying a “sports” switch for the equivalent of a couple of bottles of vodka, but with such an investment the power will increase significantly and the maximum speed will increase by about half.
Essentially the issue
What is a “sports” switch? This is the most ordinary switch with only a built-in module that regulates the ignition timing and that’s all. The module can be fully automatic, programmable or with a manual corrector.
In the world of high technology (relax, scooters are not one of them) - the ability to change the ignition timing is a very useful thing, but only if your engine is tuned to deliver maximum power in the high speed zone, that is, boosted in speed. In all other cases, the effect of installing a supposedly “sports” one will be zero (at least for you).

One such solution for cars is a switch . At one time, the world of the car turned upside down. Here's what it is and why. switch in the car and we will analyze it in our article.

Features of the ignition switch
Even the first cars were equipped with a combustion system based on a battery , and the peculiarity of the operation was the use of the principle of self-induction. It should be noted that, despite all its advantages and disadvantages, this scheme was used for quite a long time until a completely new element base appeared.
The least complex solution was based on a simple transistor circuit that controls the currents flowing through the ignition coil. The result is a device called an electronic voltage switch. Compared with the primary source, the basic principle remains the same, based on the phenomenon of electromagnetic induction.
However, transistors began to be used as electronic switches that reduced the load on the chopper contacts while increasing the current flowing through the coil windings.

The functional reliability of the ignition system in general has been increased;
There were guarantees of its effectiveness at significant engine speeds and, accordingly, at high speeds;
It became possible to increase the engine compression ratio.
Further development of the ignition system switch
Whether the switching circuit is based on transistors or thyristors, its key advantage is the significant improvement in ignition performance. As a result, the complete displacement of the dominant at a certain point in time ignites the battery . When developing a new circuit, we managed to abandon contact voltage switches, which were replaced by modifications equipped with proximity sensors, for example, a Hall sensor.

The basic principle inherent in the ignition system is to increase its reliability while simultaneously increasing efficiency. As a result of the improvement of electronic components, control units have become microprocessors; they process signals coming from several sensors, which significantly improves the quality of control of the ignition process.

As a result, dual-channel switches were first introduced into systems, followed by systems with individual coil and switching devices for each spark plug.
Design development allows you to achieve:
Getting a more powerful spark;
Removing from the design a part of a mechanical device that reduces the device’s resistance to failure;
Elimination of losses incurred by the distributor due to its removal from the structure;
Idle resistance;
Improved starting at lower ambient temperatures;
Reduced fuel consumption.
In general, the introduction of switches in ignition system has improved vehicle reliability and stability.
What are the signs of a switch failure?
With the introduction of the switch into the design process, diagnosing problems arising from the failure of the engine to start normally becomes more difficult. For the most part, only a specialized workshop can correctly determine the breakdown, which:
Inability to start the engine due to lack of spark;
The power supply is unstable, there is a delay shortly after startup.
If a known good device is installed instead of the switch, these symptoms will immediately disappear. This replacement. The easiest way to check the functionality of this electronic component. There is another operational method for determining the performance of a device by indirect indication. A voltmeter is connected to the circuit, the ignition is turned on without starting the engine.

Initially, the voltmeter needle is fixed in a certain position, but later it deviates to the right, indicating the normal state of the switch.
It is important that startup degradation is not always due to switch failure; wires and, above all, the condition of the connectors and the ground contact. It will not be superfluous to check the Hall sensor.
In any case, the advent of voltage switches on cars has led to significant improvements in starting efficiency and engine quality in all modes of operation.
Don't be a sucker, read technical literature instead
What sadness do you and I care about the problems of a merchant? Well, the trader has a desire to take money from the suckers, so let him take money from them, so what do we get from them? Yes, in principle, that’s what the suckers need - let the traders put them on shoes, who’s to blame. Instead of sitting in your VK, it would be better to read some technical literature or at least learn a few technical terms. Otherwise they will see a “hall sensor” on the price tag on the counter and think that this is actually a hall sensor...
Moped owners will be very interested in learning how to properly install the switch on your moped.
Switch on car and scooter
Many car enthusiasts may be surprised, since they know that checking the switch on a car is a matter of minutes. To do this, you just need to use a voltmeter, which sometimes even comes directly with the car. You just need to know where to connect what, and no problems arise at all. However, in the case of a scooter, things are a little different.
If you want to know how to check the performance of the switch on your scooter yourself, then you should remember that you will not be able to achieve accurate measurements if your switch remains in the same place where it always is. All this will be discussed more specifically a little later, but for now you just need to understand that checking the switch on a car and on a scooter are slightly different things, so you shouldn’t think that the process will be identical. Read on and you will learn how to test the switch on a scooter with a multimeter, just like on a car, and what are the disadvantages of this method.
DC switch
Due to its ease of connection, this is one of the most common moped switches. The most basic model has only 4 contacts:
- Ignition coil
- Hall Sensor
- Plus(12V);
- Minus
Switches of this type exist in various modifications:
- with max. limiter rpm
- without limiter
- with additional contacts
- with changing ignition timing
AC switch
This type of moped switch works great without 12V DC. Despite its simpler design, it has a slightly more complicated connection to the moped's electrical circuit. This type of switch, due to its small size, exists without a max. limiter. rpm, and can also work in conditions under which the DC switch is inoperable. That is, by removing the battery, the ignition switch, and the relay-regulator, the moped with the AC switch will start and drive.
Alfa moped switch
In this part of the article, we will look at the pinout feature of the switch for the Alpha moped (and, to boot, the Delta), and also find out the purpose of each wire. All information is presented in the diagram below.
It is noteworthy that the same switches can be installed on mopeds of various brands of Chinese production, since there are a lot of Alpha clones.
As we can see, the pinout of this switch is very simple.
Pinout
- Black and yellow wire 1
goes to the ignition coil. - Black-red wire 2
is responsible for power. - Contact 3
is missing in principle. - Black and white wire 4
is responsible for turning off the engine and goes to the ignition switch. - Blue-white pin 5
goes to the Hall sensor. - The last, green pin 6
is ground.
Pinout
If you have a 4T motor installed on your scooter, the pinout of the switch will depend on what type the scooter requires. For DC it will be as follows:
- The leftmost terminal on top should connect to the generator sensor.
- Ground is connected to the terminal located under it. You can tie the negative wire, for example, to the body of a moped; it is important that the part is metal.
- The upper terminal, located in the center, is connected to the wire leading to the ignition coil drive.
- The one located under it is also connected to the negative wire (ground).
- The wire from the ignition switch is connected to the upper rightmost terminal, which is needed to turn off the engine.
- The power wire is connected to the terminal located under it; it also comes from the ignition switch.
