Known in Soviet times, "Sarkana Zvaigzne" is a Riga motorcycle plant specializing in the production of light mopeds. At that time they were one of the best representatives in their category. The eleventh model replaced the seventh series. The only change was the removal of the fuel tank at the rear over the frame, which made it easier to ride downhill. As a power unit, the equipment was equipped with a two-stroke engine with a power of 1.2 horsepower, with a volume of forty-five and a half cubic centimeters. When the device developed a speed of up to fifty kilometers per hour.

"Riga-11": technical characteristics

• weight is 45 kilograms with a maximum possible load of 100 kg;
• length / width / height - 1.97 / 0.75 / 1.15 meters;
• wheelbase - 1,200 millimeters;
• limit indicator of design speed - forty kilometers per hour;
• front suspension - telescopic fork with spring shock absorbers;
• a similar rear element is of a rigid type;
• brake unit - drum type with individual drive for each wheel;
• type of frame - spinal welded construction.

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

Power point

As for the motor of this vehicle, the following can be noted:

• two-stroke carburetor engine brand D-6;
• its working volume is forty-five cubic centimeters;
• cooling - air with chamber purge (crank device);
• cylinder size is 38 millimeters;
• compression ratio - 6, with a piston stroke rate of 4.4 centimeters;
• The engine produces maximum efficiency at four and a half thousand revolutions per minute.

The Soviet moped is equipped with a single-stage gearbox, a two-plate friction clutch, and reaches a torque of up to 29 Nm. The power unit is started by turning the pedals. The ignition unit is a magnetic system. Waste exhaust is discharged through a muffler with baffles for throttling. With a gear ratio of 4.2, the identical chain ratio is 4.1 (the carburetor used is K-34).

Peculiarities

"Riga-11" - a moped that had certain improvements compared to previous similar models. The spinal frame consists of a central tube, to which the clamps of the front fork, motor and some other parts are welded. She became stronger and more resilient. The Soviet moped in question was the first modification equipped with a spinal-type frame.

The weakest link in the design of the vehicle was the wheels. However, compared to the seventh variation, they received an increased section and did not deform so quickly when driving on uneven roads with potholes. The design of the wheels itself 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. The clutch and front brake on the levers are equipped with tips in the form of balls that protect against injury when falling.

Device of other nodes

Improved seat arrangement. His box has become more powerful, and the thickness of the pillow has also increased. This decision made it possible to make the driver's seat more comfortable and increase the usable space for storing tools. The seat spring is fixed with new elements that ensure the reliability of the entire assembly.

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

Thanks to a solid power reserve, Riga-11 is a moped that has become popular both among urban residents and in rural areas. The engine remains the same, but the chain is made in a new, stronger and more durable version. Because of the wide tires, the motor was shifted 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"

It is quite problematic to find consumable parts for the equipment in question now. This applies to original spare parts. Analog variations can really be picked up or ordered, since they are simple and unpretentious.

During the serial production of the moped, spare parts were available in sufficient quantities. Many users themselves sorted out the engine and other components, trying to improve or repair them. This is quite within the power of a person who has minimal knowledge about the structure of two-wheeled units.

The motor plus the pedal, and the result was a relatively fast and affordable vehicle.

Motorbike B-901

Today, young people dissect on scooters - and in the days of the USSR, mopeds performed their role. They cost much cheaper than even an overwhelmed motorcycle - from 100 rubles, it was not necessary to store a moped in the garage - they, like bicycles, were quietly kept in an apartment. Those who did not have mopeds often helped their happy owners to repair the vehicle - suddenly they would let them ride with the breeze.

Motorbike B-902

The first Soviet motorbike mass-produced. These beauties were produced back in the 50s at the Kharkov Bicycle Plant. Such mopeds had a low frame and a reinforced fork, 26-inch wheels, a steering wheel with extended handles, a trunk with a clamp and a D-4 engine (“hole”, as it was called). They weighed 27 kg.

Motorbike MB-042 "Lvovyanka"

Such models have been made at the Lviv Automobile Plant since 1960. They could accelerate up to 40 km / h (power - one horsepower), had a front fork with spring shock absorbers that swiveled left and right, and a welded tubular frame with two upper tubes. The stiffness of the shock absorbers could be adjusted by screwing and unscrewing the nuts. Motor D-4, rigid rear wheel suspension.

Lviv mopeds MV-044, MP-043

Model 1982. The most compact moped produced by this plant: it could not only be stored on a balcony, but also carried in a car trunk. True, he weighed more than decently - 50 kg. The wheels were like those of a motor scooter - small and plump; the steering wheel and seat could be lowered.

Moped MP-048, aka "Verkhovyna-3"

They almost did not differ from each other. The light moped MV-044 was equipped with a D-5 engine and had a power of 1.2 horsepower. On the MP-043 moped there was a more powerful engine - Sh-51; power - 2 horsepower.

Spiriditis moped

A new model of the same car factory has been produced since 1963. This device, although it was called a motorbike, actually had all the advantages of a moped: it had a telescopic front fork, a rear spring suspension, and a stamped frame. And the motor, of course. Later models were even equipped with as many as two shock absorbers.
Single-cylinder two-stroke engine, volume 45 cm3, power - 1.2 horsepower. This pleasure weighed 30 kg, and the speed developed up to 40 km / h.

Bicycle "Riga-1" with a motor

These experimental models began to be produced in 1958 at the Sarkana Zvaigzne motorcycle plant in Riga, created on the basis of a nationalized bicycle factory. The 60 cm3 motor, created under license from the Czech plant Jawa, did not save the situation - the model was unsuccessful. It was then that the designers of the Riga plant were sent to the Czech Republic to learn from the experience of Jawa employees. As a result, the Riga-1 moped was created: a telescopic front fork, a rear suspension on springs, a 50 cc block motor manufactured at the Jawa factory (although later the motors for these mopeds began to be produced in Lithuania).

Light moped "Riga-2 Gauja"

At about the same time, these bicycles began to be equipped with d-4 motors with a volume of 45 cm3. After equipping - and it happened in Leningrad, at the Krasny Oktyabr plant - tuned, as they would say now, bicycles acquired a power of 1.2 horsepower.

Moped "Riga-4"

A 45cc motor, a tubular front frame, a spring-loaded front fork - and a headlight that is powered by a generator and allows you to ride in the dark. These models were produced from 1961 to 1963.

Moped "Riga-5"

Went on sale in 1970. The engine of this moped had a tricky volume - 49.9 cm3; this meant that such a moped did not need to be registered with the traffic police and it was not necessary to have a motorcycle driving license to ride it. Power - as much as two horsepower. The model was equipped with wheel guards and 16-inch wheels - before mopeds had wheels 19 inches in diameter.

Moped "Riga-11"

Produced from 1966 to 1971. It was extremely simple to manage, but the dynamics, compared to previous models, left much to be desired. Instead of a telescopic fork, compressible springs were fitted to the front wheel for shock absorption. The engine was started by pedaling.

Moped "Riga-12"

He had only one speed, but the wheels were amazingly powerful, and a rear position lamp and a headlight could be connected to the D-6 engine. Alas, the frames of such models did not differ in strength, and they themselves were very heavy.

Moped "Riga-13"

His saddle was short, the trunk was small - but there was a special air filter built into the frame. The moped also had bicycle pedals - so that when driving uphill, you could help the Sh-57 (Šiauliai) engine if it could not cope.

Moped "Riga-26"

It was perhaps the most attractive model of those years - the D-8 engine, a very well-installed light and even a high-voltage transformer, with the help of which the problems with the ignition coil, characteristic of previous models, were eliminated. Such mopeds did not go out of production until 1998 - and were launched in 1983.

Moped "Karpaty-2"

They were produced from 1970 to 1973. Developed such a moped speed up to 50 km / h. It weighed 51 kg, withstood a load of 101 kg, had a 5-liter fuel tank.

In October 1976, the Riga motorcycle plant "Sarkana Zvaigzne" replaced the base vyu model of a light road moped. "Riga-7" was replaced by "Riga-11". The basis of the new moped was a spinal frame with a powerful central tube, much stronger and more durable than the frame of the previous model. Accordingly, the front fork has changed. The owners of Riga mopeds produced in the first half of the 70s complained about the insufficient strength of the wheel rims. Designed for the smooth roads of the Soviet Baltic states, the wheels could not withstand driving on the broken roads of most republics, primarily Russia. The designers of "Riga-11" went towards the consumers of the pits. Reinforced rims and tires with a larger section (2.25-19 instead of 2.00-19) provided Riga wheels with durability on the road surface even in disadvantaged regions.

A taller handlebar and a new comfortable saddle with thicker pads improved comfort, while ball-shaped clutch and front brake levers were designed to protect the rider's hands from injury in the event of a fall. A feature of the moped "Riga-11" was the gas tank, mounted not on the frame above the fender of the rear wheel, but under the trunk. It also served as a base for luggage. The tank held only 4 liters of fuel, but on them a moped with a serviceable, well-adjusted engine could travel up to 200 km.

The D-6 engine remained from the previous model, but due to the use of wide tires, so that the driving and driven chain sprockets were in the same plane, the engine had to be shifted to the left by 7 mm. A working volume of less than 50 cm 3 made it possible to ride a moped without a driver's license. Officially, in the Soviet Union, a teenager who had reached the age of 14 could drive such a vehicle.

Technical specifications

Spriditis

The production of mopeds at the Sarkana Zvaigzne factory (Riga) started in 1958. The experience was not entirely successful. These were Spiriditis mopeds with a 60 cc engine. licensed from Java. The first pancake turned out to be a lump, the designers of Sarkan Zvaygzne went to the Czech Jawa plant for a detailed acquaintance with the production of small-capacity motor vehicles.

Riga-1

This is how the first Riga-1 moped appeared, the release of which began in 1961, although it was developed two years earlier. The moped was equipped with a 50 cm3 Jawa engine, which required registration with the traffic police and a motorcycle license, which negatively affected the demand for this model.

Motorbike Riga-2 "Gauja"

From 1961 to 1963, the plant produced Gauja motorbikes. A D4 or D5 engine with a power of 1 hp was installed on a single moped. The reliable welded frame was lightweight, and the front suspension had spring shock absorbers. For driving at night, the moped was equipped with a headlight, which was powered by a generator. Gauja developed speed up to 40 km/h.

Riga-3

In 1965, "Riga-1" was replaced by "Riga-3". With external similarity, the new model received the Sh-51 engine of Šiauliai production. However, these engines turned out to be rather unreliable and the popularity of the Riga mopeds was shaken again. Outwardly, Riga-3 was distinguished by a different shape of the gas tank, a pillow-type seat and a frame with an elongated tail section. In addition, "Riga-3" was more powerful than "Riga-1" by almost a third, lighter by 2 kg and could accelerate to 50 km / h.

Riga-4

In 1970, the plant introduced a new model "Riga-4" with a 49.9 cm3 engine (which did not require a license) and a power of 2 hp. Of the innovations: a high-voltage transformer appeared, wheel guards, the trunk changed, the design of the chain changed, the gear of the gearbox changed, a new trunk was installed, and the speedometer was driven from the engine. But the main thing is that for the first time on a moped, instead of 19-inch wheels, 16-inch wheels were installed. This is probably why Riga-4 no longer looked so Soviet.

Riga-5

From 1966 to 1971 Gauja's successor Riga 5 was produced. By design, it was quite different from its predecessor. For example, for depreciation of the front wheel in Riga-5, not a telescopic fork was used, but compressible springs, allowing the fork to bend forward. The design has changed. There were no gears, the D-5 engine was started by pedaling. Despite the ease of control, the dynamics of the moped has deteriorated significantly. The frame was strengthened, because. past models sinned with breaking frames. In 1971, "Riga-5" was replaced by "Riga-7".

Riga-7

The new Riga-7 moped began to be produced in 1969 in parallel with the Riga-5. The new model completely replaced the old one by the end of 1971. The main difference is the D-6 engine, which allows you to connect a headlight and a taillight to it. The new moped has a glove compartment for tools, a silencer, interchangeable wheels and shields. In the design of "Riga-7" there was a special rail that prevented the frame from breaking in case of emergency braking. In 1976, the Riga-7 moped was discontinued and replaced with the Riga-11.

Riga-11

After the Riga-7 moped, the new Riga-11 was born - a stylish single-speed moped with powerful wheels. The D6 engine was retained. But, the model turned out to be quite heavy, and the frame is not strong enough. In addition, the original tank, located under the trunk, in practice brought a lot of trouble when driving uphill, especially when there was little fuel left.

Riga-12

"Riga-12" was produced from 1974 to 1979. It was equipped with a Šiauliai Sh-57 engine and had bicycle pedals that could be used to help the engine when moving uphill. The model was distinguished by the presence of a paper air filter mounted in the frame. It was produced with different mounting options and fuel tank shapes: with an ignition coil on top of the frame under the tank, with an ignition coil on the bottom of the frame under the tank. Visually, it was very similar to the Riga-16, but differed by a short saddle and a smaller trunk.

Riga-13

The light moped "Riga-11" was replaced by the most successful moped of that time - "Riga-13". It was produced since 1983 and was equipped with a 1.3 hp engine, which accelerated the moped to 40 km/h. Early models were equipped with a D-8 engine, and later they began to install engines - D-8e, D-8 m. Its distinguishing feature is good light and an installed high-voltage transformer, which eliminated frequent problems with the ignition coil. "Riga-13" became the most massive moped of the plant and was produced until 1998.

Riga-16

In 1977, the two-speed Riga-16 model was put into production. The moped had a motorcycle-style muffler, kickstarter, rear brake lever, taillight, original paint job, and a new handlebar. The first models were equipped with the Sh-57 engine from Siauliai, and later versions received the most successful Sh-58 engine. In fact, "Riga-16" is the first mokik in the USSR (before that there were mopeds with pedals). With its own weight of 45 kg, the mokik could carry up to 115 kg of cargo!

Riga-22

In 1981, the plant began producing the Riga 22 mokik, which was a modernization of the Riga 16 model and was equipped with the Sh-62 engine. The engine was radically different from its predecessors. In particular, it had a powerful electronic contactless ignition. The direction of rotation of the crankshaft had to be changed due to a different gearbox. But, the good design was let down by the quality. Therefore, in 1984, the entire system was modernized and the engine developing 1.8 hp became known as Sh-62M. At the same time, the design of the muffler has changed. But the gearbox was still the weak link of the Riga 22 mokik.

Riga-26 / Riga-30 / Riga-Mini

In 1982, the plant introduced a very unusual mokik "Riga-26" (or "Mini" RMZ-2.126). It became the most compact in the history of the plant and easily fit not only on the balcony, but also in the trunk of any Soviet station wagon. He only weighed 50 kg. "Riga 26" was distinguished by small plump wheels, like scooters, and the steering wheel and seat could be lowered, making the mokik even more compact. The engine is Sh-62, V-50 or V-501, all of them are from Siauliai plant.

Delta

By the mid-80s, the market was experiencing an overproduction of mopeds, so the factory decided to concentrate on new models of mokiks. In 1986, a completely new development was introduced - the Delta mokik (RMZ 2.124). The original frame and the successful engine were the key elements of the success of this model. Delta received a two-speed V-50 engine from Siauliai, which took into account many of the shortcomings of previous models. And the foot shifting in the B-501 engine was generally admired by bikers. Deltas were produced in small batches with cast wheels and three-speed Polish-made engines.

Stella

Following the Delta, the Riga plant showed the Stella mokik. An M-225 engine from a Babetta moped was installed on it. After the collapse of the USSR, Stella, in addition to engines from Babetta, began to install engines from the Polish mokik Dezamet and French Peugeot engines.

In the 90s, the factory "Sarkana Zvaygzne" stopped producing mopeds. Despite all attempts to stay afloat, the production of mopeds and mokiks was stopped in 1998, and the Riga motorcycle plant began to be sold in parts. It's a pity, because now mopeds and scooters are a very popular mode of transport, but we have to buy equipment from the Chinese ...

With serial mopeds of the Riga plant, it seems, everything. But the plant "Sarkana Zvaygzne" during its existence has created a lot of experimental and sports models. About them - in the following blogs. Subscribe!

He began to produce a new model - "Riga-11". Many years of experience in operating previous models, especially in rural areas, revealed the need to improve a number of components and parts. Their modernization made it possible to significantly improve such important qualities of machines as reliability, traffic safety and ease of operation. At the same time, it was possible to give them a more attractive appearance. Consider the main design innovations.

The backbone frame is a strong central tube to which the fastening elements of the front fork, engine, rear suspension pipes and other parts are welded. It is distinguished from the previous frame by greater rigidity and durability. In connection with the change in the frame, the dimensions of the front fork became different, although the technical parameters remained the same. Note that "Riga-11" is the first serial model in the USSR with a spinal frame. The weakest point in the design was the wheels, the rims of which often failed when driving on uneven roads, with stones and potholes. The use of tires with an increased cross-section (2.25-19 instead of 2.00-26 inches) and a reinforced rim on the Riga-11 practically ensures the long operation of the machine even in difficult road conditions. The design of the wheel elements remained unchanged.

For a more comfortable fit for the driver, the steering wheel is made high. The fastening method - using two earrings with nuts - allows you to easily and securely fix it in the most suitable position. Clutch and front brake release levers are equipped with rubber ball-shaped tips to prevent injury in the event of a fall. The design of the saddle has been changed - its box and cushion thickness have been increased. This is done to improve the rider's position and add room for the tool. New elements are used in the seat spring mounting, which ensure high manufacturability and reliability of the entire assembly.

The fuel tank located at the rear of the moped, together with the trunk, forms a rather large platform on which up to 15 kg of cargo can be transported. The rack of the trunk prevents the load from slipping and at the same time serves as a handle for moving the moped. The volume of the fuel tank (4 liters) provides a cruising range of up to 200 kilometers. This allows you to make quite long trips on roads remote from the gas station, trips "to nature". Citizens - fans of such trips and rural residents, of course, will be glad to see a stronger and more durable chain in the motor transmission on the new car.

The engine on the "Riga-11" is the same as before,. But because of the wide tires, it is shifted to the left of the plane of symmetry of the frame by 7 mm, so that the front and rear sprockets of the final drive are located in the same plane. The stand is made more durable, and at the same time technologically advanced.
