"Riga-11" (moped): technical characteristics and features

Famous in Soviet times "Sarkana Zwaigzne" - the Riga motor factory specializing in the production of light mopeds. At that time they were among the best representatives in their category. The eleventh model changed the seventh series. The only change was the removal of the fuel tank from behind the frame, which facilitated the trip to the slope. As a power unit, the equipment was equipped with a two-stroke engine with a capacity of 1.2 horsepower, a volume of forty-five and a half cubic centimeters. When the engine was air-cooled, the vehicle developed a speed of up to fifty kilometers per hour.

Riga-11: specifications

The main parameters of the moped are as follows:

• Weight is 45 kilograms at the maximum possible load of 100 kilograms;
• Length / width / height - 1,97 / 0,75 / 1,15 meters;
• Wheelbase - 1,200 millimeters;
• The limiting index of the design speed is forty kilometers per hour;
• Front suspension - telescopic fork with spring shock absorbers;
• Similar rear element - hard type;
• Brake unit - drum type with individual drive for each wheel;
• Type of frame - spinal welded construction.

"Riga-11" - a moped, which was produced with a tire size of 2.25 by 19 inches.

Power point

As for the motor of this vehicle, we can note the following:

• Two-stroke carburetor engine brand D-6;
• Its working volume - sork five cubic centimeters;
• Cooling - air with chamber purging (crank device);
• The cylinder is 38 millimeters in size;
• The compression ratio is 6, with a piston stroke of 4.4 centimeters;
• The maximum efficiency the engine produces at 1.2 horsepower at four and a half thousand rpm.

The Soviet moped is equipped with a single-stage gearbox, a two-disk friction clutch, reaches a torque of up to 29 Nm. The power unit is started by turning the pedals. The ignition assembly is a magnet system. The exhaust emissions are produced through a silencer with partitions for throttling. With a transfer value of 4.2, the identical chain transfer ratio is 4.1 (the carburetor used is K-34).

Features

Riga-11 is a moped, which had some improvements, compared to previous similar models. Spinal frame consists of a central tube, to which the fixators of the front fork, motor and some other parts are welded. She became more rigid and hardy. The considered Soviet moped was the first modification, equipped with a frame of spine type.

The weakest link in the construction of the vehicle was the wheels. Nevertheless, compared with the seventh variation, they received an increased cross-section and were not so quickly deformed when driving on uneven roads with potholes. The very design of the wheels remained unchanged.

The high steering wheel provides a comfortable fit for the driver, fastened with a pair of clamping elements with nuts. This solution allows you to quickly and reliably change its position. Clutch and front brake on the levers are equipped with tips in the form of balls, protecting from injury when falling.

Device of other nodes

Improved saddle device. His box became more powerful, and the thickness of the pillow also increased. This solution allowed to make the driver's seat more comfortable and to increase the useful space for storing the tools. Seat spring is fixed by new elements, providing reliability of the whole unit.

The fuel tank, together with the trunk, is located at the rear of the moped, forming an impressive platform capable of withstanding 15-20 kilograms of cargo. The volume of the fuel tank is four liters. This stock is enough for about two hundred kilometers.

Thanks to the solid stock of the course "Riga-11" - a moped, which became popular both among urban residents and in the countryside. The engine remained the same, but the chain is made in a new, more durable and durable version. Because of the wide tires, the motor was moved to the right of the symmetrical point of the frame by seven millimeters. This allowed the front and rear sprocket to be located in the same plane.

Spare parts for mopeds "Riga-11"

Expendables for the technique in question are now quite problematic. This applies to original spare parts. Analogue variations can be chosen or ordered, as they are simple and unpretentious.

During the mass production of the moped spare items were available in sufficient quantities. Many users independently looked through the engine and other nodes, trying to improve or repair them. This is quite possible for a person who has minimal knowledge about the arrangement of two-wheeled units.

Customer Reviews

The owners of the equipment in question recall that Riga-11 is a moped, which became the embodiment of a childhood dream. Its simplicity and low price, along with modernization, have become the determining factors of the popularity of this transport in towns and villages across the country.

Among the pluses in the car is the following:

• More stable wide wheels;
• Modernized saddle;
• Strong and practical moped frame.

Now users are more nostalgic for those moments when they could personally go through the whole mechanism and be proud of it. In modern times, this vehicle serves primarily as a museum exhibit or a memorable rarity.

Nearest competitors

Among the mopeds of that time, Riga-11 did not have a lot of competitors in its class. The aggregates from the same manufacturer under the indices 7, 12 and 16 were popular. From the eleventh modification they differed in the arrangement of the gas tank, the frame structure, the width of the wheels and some modifications of the motor. The rest of the mopeds were almost identical.

Of the other Soviet manufacturers that produce competitive equipment, we can mention "Carpathians" and "Verkhovyna". It is worth emphasizing that many spare parts for mopeds were interchangeable, easy to operate, maintain and repair.

Conclusion

To summarize, it can be noted that Riga-11 is a moped, which was a success not only among urban, but also among rural residents. This is due to the wide wheels and decent capacity of the trunk, which made it possible to transport up to twenty kilograms of cargo on bad roads at a speed of about forty kilometers per hour.

The vehicle under consideration became the first two-wheeled light vehicle that was equipped with a spine-type frame. In addition, the seat was modified, as well as clutch and brake levers, which increased safety and ease of fit.
