Moped from China Delta - review and technical specifications

Chinese companies are well versed in the needs of people, and, realizing that many people need simple and inexpensive equipment, they decided to come up with a cheap moped called Delta.

This moped appeared in Russia and nearby countries not so long ago, around 2007, but even then it began to enjoy unprecedented popularity. When this type of moped entered the market, the price of the Delta moped was very low, because I remember from my own experience that when this moped appeared, the price started at 800 UAH. (2500 rubles). As you can see, this is a meager price for new equipment, albeit a small one. Also, this price was for a moped, which was then called the Farmer, but in principle this is the Delta.

Pros:

1. Low price
2. Large selection of parts
3. Good handling and simple design

Minuses:

1. Compared to Japanese technology, they do not have a long shelf life.
2. Some parts are of poor quality.
3. Low power.

Delta tuning

The first reason for tuning is poor assembly of parts. Of course, the materials themselves do not cause any complaints, but the assembly, tightening of bolts and gaskets leave much to be desired. Therefore, before starting operation, you need to spend a little time checking the fasteners and possibly replacing them. A similar action is performed with gaskets. It’s difficult to call this a full-fledged tuning, but it’s still an improvement of the moped.

The second most common tuning item is increasing the fuel tank. This action can already be called a full-fledged delta upgrade. Since the moped is designed for 2 passengers of average build or a driver with a load, a basket for things is installed on the frame in front of the seat. Behind the driver's seat is the passenger's seat.

There are 2 options for changing the moped, each of which will be considered:

1. The basket is removed from the frame and an enlarged tank is attached in its place. A standard tank is enough for a little over 200 km. However, an additional mounted tank solves this problem. In this case, the passenger seat remains. Thus, the delta can only transport people.
2. The second option is similar to the first. The tank is attached in the same way, but the passenger seat is removed and a net for things is put in its place. It turns out to be a convenient vehicle for one person with the ability to transport small loads.

These changes are not complicated. Anyone can do such tuning of a delta moped with their own hands. But there are also more complex options for changing the technical and visual characteristics of a two-wheeled horse, allowing you to discover new sides in it.
