Hai! If you are only interested in the electronics of this moto, then you need our section "Motorcycle Schematics". Those who are looking for a description with a photo based on reviews and technical specifications of the Izh Jupiter 2 moto, which you can buy today, then you have come to the right place. The article is devoted to the most important features of this bike, which has survived more than a dozen difficult years. Our team tried to fully reveal the advantages and disadvantages of this two-/three-wheeled vehicle.
Description Izh Jupiter Second generation with photo
The aforementioned iron horse is a middle-class road bike, the operation of which is designed for roads with a variety of surfaces. The production of this steel horse was mastered at the Izhevsk Machine-Building Enterprise, located in distant Udmurtia. This motorcycle became a continuation of the line of medium-weight multi-purpose motorcycles produced in Soviet Russia. The very first representatives of the mass series left the assembly line in the middle of the distant 1960s. The steel horse was produced until 1972. The bike became the embodiment of the desire of the design engineers of the USSR to create a two-cylinder bike.
It should be noted that as for the first Udmurt iron horse with such a frisky engine, the motorcycle turned out well. He had at his disposal the power of 19 horsepower with a rather modest, as for that time, engine capacity of 347 cc. In addition, a very good lead-acid battery was installed on a two / three-wheeler.
Reviews about the Izh Jupiter 2 motorcycle in the past were mostly positive. However, over time, domestic motorcycle enthusiasts have changed their views on the reliability of the iron horse. It's all the fault of the developers' miscalculations in the bike's electronics. He often lost the ignition timing. Yes, and the bearing under the rotor part of the generator was distinguished by accelerated wear, which greatly upset the owners of the motorcycle. Far from every village owner already wanted to buy a second-generation Yupac.
It is curious that the above Izh, despite the short history of production, was produced in a variety of modifications. Classic loners, models equipped with a sidecar and even anniversary motorcycles left the assembly line. In the last year of release, the transitional world saw a model that received eighteen-inch wheels, as well as beautiful glove compartments. On the latter there was a typical later inscription with the name of the series.

In my childhood of the 90s, when most people did not have computers and spent their free time on the street, the time came when the owners of first mopeds appeared in the yard. mostly holes with pedals, less often in the Carpathians and Riga. A year or two later, they already came to the yard at Voskhod, Minsky, Izhakh, most often without documents and without category “A” rights. Owning Java, and even more so the latest model at that time, was the height of steepness. But most of my peers 14-16 years old moved on two wheels with pedals and a two-legged drive, jealous of the guys in helmets.
The boy of those years could not have a motorcycle for several reasons:
1. Parents do not allow. (and rightly so).
2. No money (in the yard of the 90s).
3. You don’t need this yourself, he doesn’t know how and in general it’s better to do homework :).
My choice was #2.
When the desire to own two-wheeled vehicles overcame all possible boundaries, the brain began to think about how to make money on it.
There are not many options at 15 years old. He dragged corn from the fields, boiled it and sold it in the market. I saved up 800 rubles in a month!
As a result, the following year, in the spring, I bought an IZH Jupiter 2 with a sidecar for 600 rubles. and gave 100 rubles for a general power of attorney.
Photo 1999. Here I am 16 years old.
That was the time! Gasoline cost 3-4 rubles a liter, in the pocket was also no more than 10 rubles. After some time, I unhooked the cradle, drove the motorcycle to the dacha and spent the whole summer and autumn riding it.
In winter, I decided to make it a cool sports bike, black and red, with a fire on the tank, with a raised wing. It is not difficult to guess what came of this, and after a year of inactivity in the garage, he was sent to the village, where he was revived and changed to grain.
Time passed, but the idea to buy IZH Jupiter 2, restore and ride remembering childhood never left.
Studying, the army, marriage, work, a small child, again work and business trips, did not give thoughts and a chance for a motorcycle and free time around it. Finally, approaching the age of 30, when my capabilities became a little closer to my desires, I sat down on the Internet in search of a Jupiter 2 in good condition and complete set.
But it wasn’t there, for everything more or less alive and intact, the owners asked for the amount that arose in their heads apparently after a strong blow, arguing that it was already a rarity and its place in the museum, and not, as it is now, near the crap .... barn .
Once I pressed my grandparents to the side of the road (he did it very politely).
I say - "Sell your father a motorcycle, I will restore it and keep it."
Grandfather - “What are you going to restore in it? He is in good condition and is generally whole. ”
- "Well, I'll paint it ... sell it, buy yourself a modern Jupiter."
- “I don’t need a modern one, I’ve been on this all my life. I’ll die, then I’ll sell”
“But how do I know that you are dead?”
- “I, he says, remembered your numbers, they will inform you”
Grandfather got caught with humor, parted. Such people do not sell their friend, children and grandchildren do it for them later. Either the price tag for a rarity, or for scrap, after they roll it away.
Months passed, it became a habit to watch ads for the sale of motorcycles in the evening. And then somehow it comes across - IZH Jupiter 2 is for sale, the price is 10 thousand rubles. The photo shows a complete motorcycle with good chrome.
There was one thing, but three weeks earlier I bought an IZH-49, around which all my free time spun. The wife looked at the ad
and said - go and pick it up, then you will regret it, we will ride together. I thank her for this, for her understanding and full support.
in my hobby.
Arriving at the place, I found that the motorcycle was assembled on a non-native frame, the right glove box was from the third series. The price dropped to 6 thousand rubles
and I was happy to take him home. It was winter, but it was impossible not to drive, especially since it started up perfectly. All lighting equipment worked, up to the signal.
In the photo I am 30 years old. Find 10 differences from the photo above))))
The motorcycle stood for a year, IZH-49 was occupied all the time ... Finally, I decided to take it apart. I already had experience of how to make less “extra movements”. Expected to take to the sandblasting and paint in the powder chamber. Under the order, I picked up a beautiful beige-milky powder color, with gloss, and took black for the frame and chassis parts in order to dilute the monotony.
Unfortunately, things didn't turn out the way I wanted. Beige powder paint was of poor quality. The output turned out to be a matte yellow color, while the black one lay well and correctly. I had to manually re-clean off the powder paint and prepare for the usual painting with cheap car enamel, for drying in the oven.
I hoped to catch the remains of chromium under a layer of dirt and oil, but, the shiny surface of the exhaust pipes, this is cleaned
shiny bare metal. I decided, until I get a donor, to paint them in the color of the motorcycle. Should not burn, on early IZHs
fully painted at the factory.
After painting. I chose blue. There are no documents for it, so I didn’t become attached to beige, which I didn’t really like
Quotes! Tape from the first experience with IZH-49 into the furnace! You need masking tape. Car masking tape ZM costs 200 rubles for 5 meters, but you need 20. I found it in a hardware store, rough, thick, but alternative at a price of 40 rubles.
I bought a very successful paint, the color from it really gives off chrome, and not silver.
Hundreds of blue IZHs leave the factory assembly line every day. This bike is also not long to wait. A few more efforts, and the car will come to life.
Motorcycle enthusiasts are well aware of the IZH-Planet and IZH-Jupiter motorcycles. Our plant has been producing them since 1961-1962. And since that time, work has been continuously going on to improve them. The reliability of the machines has increased significantly, and thanks to this, the warranty mileage of motorcycles has been increased by 20 percent.
Factory designers are working not only to eliminate the flaws identified during operation, to improve the model on the conveyor. Our design bureau also prepared new, modernized models of motorcycles, paying special attention to such qualities as reliability and durability. Now all work on the creation and testing of new machines has been completed. "IZH-Planet-2" and "IZH-Jupiter-2" are ready for launch.
How do they differ from their well-known predecessors?
The first thing that catches your eye is the appearance. New machines are more in line with the requirements of modern technical aesthetics. Motorcycles are painted in a single, corporate color. The wheel rims, muffler housings are covered with a layer of decorative chrome plating, and the protective covers of carburetors and brake covers are covered with hammer enamel. Crankcase covers due to polishing found a mirror finish. The saddle cover made of colored textvinite looks quite modern. By the way, the double saddle itself is somewhat wider than usual and more comfortable in shape.
The power of the new "Jupiter" remained the same, but the IZH Planet-2 motorcycle became more than two horsepower stronger. This made it possible to improve the dynamic qualities of the motorcycle and increase the maximum speed to 105 km/h. Increasing power to 15.5 liters. With. achieved by reducing the volume of the crank chamber, a slight increase in the compression ratio and the use of a K-36Zh carburetor with a diffuser diameter increased to 27 mm.
Without dwelling on the design features of the new carburetor, we want to briefly talk about its advantages over the previously used K-28. The scheme of the K-36Zh carburetor with a fuel corrector removed from the diffuser zone provides a more economical composition of the mixture and a reduction in fuel consumption by 4-6 percent. The enrichment of the mixture in the K-36Zh carburetor, unlike the K-28, is achieved by rotating the corrector lever clockwise. You need to use the corrector when starting the engine in cold weather and when driving at maximum speed. The flange fastening of the K-36Zh carburetor to the inlet pipe with two bolts is stronger than the K-28 fastening, in which the clamps often broke.
The bearing design of the secondary shaft of the gearbox has undergone a change. In the new roller bearings, the length of the rollers has been increased from 8 mm to 12 mm. However, they are installed without changing the seats in the crankcase. This is especially important for engine repair and spare parts provision. In addition, the barrel-shaped rollers allow for a more even distribution of stress along the length. Extended, bubbling rollers will increase bearing life by more than 1.5 times.
Now a few words about the changes in IZH-Jupiter.
Although the durability of the bearing of the lower head of the crankshaft
IZH-Yu is quite sufficient and the bearing can withstand over 30 thousand kilometers, there are cases of its premature failure. This is due to exceeding the permissible speeds in each gear or “gasping” at idle during warm-up, when the shaft revolutions significantly exceed the maximum power revolutions.
The redesigned connecting rod has now improved bottom smut roller bearing lubrication. This, in turn, increased the resistance several times when the engine was running at high speeds. Changed worm shaft and shift forks. This is done for a clearer and more durable operation of the switching mechanism.
Rice. 1. Oil seals protecting wheel bearings: a) a felt seal used on the IZH-Planet motorcycle, b) a motorcycle rubber seal
An important innovation that increased the overhaul run of Planeta and Jupiter is a new design of oil seals to protect wheel bearings from dust and moisture. Previously, a felt gland served for this purpose (Fig. 1, a). It did not provide sufficient sealing and, moreover, required frequent replacement. Rubber seals (Fig. 1, b), which replaced the felt ones, almost doubled the service life of the bearings.
Rubber sealing rings are also installed in the pendulum fork.
They significantly improve the protection of the fork bearings and thus increase their service life.
Rice. 2. Location of the brake light switch: a) brake light switch on the frame of IZH-Planet, b) brake light switch IZH-Planet-2 in the tool box.
In spring and autumn, the brake light switch (Fig. 2, a), mounted on the frame under the brake lever, brought a lot of trouble to motorists. It was not tight enough and often failed due to oxidation of the contacts.
The new switch design shown in fig. 2, b (it is located on the tool box), ensures its reliability in any conditions.
Both models have new relay-regulators. They are distinguished by the best vibration resistance and stability of adjustments, and this is important for the reliable operation of the engine.
On IZH-P2 and IZH-Yu2, a special polyethylene tray is placed under the battery. It will protect the toolbox from corrosion due to electrolyte ingress.
The modernization of motorcycles also touched on such important components as brakes. Analyzing the operating experience of tens of thousands of cars, the designers came to the conclusion that with a large mileage, the brakes sometimes lose their reliability. Moreover, the adjustment of the brake system does not help either - the linings and ends of the pads wear out. As a result, when the cam is fully rotated, the pads are weakly pressed against the brake drum. During repairs in such cases, steel strips were welded to the end of the pads to compensate for wear. A special compensator is provided in the new design of aluminum cast brake pads. Now, with a lot of wear, under the steel heel located at the end of the pad, you just need to put the washer, which will be included in the complete set of the motorcycle. Comparing the old stamp-welded and new - cast - pads, it can be noted that the design of the latter is much more rigid. Pressing a steel bushing into the seat under the brake cam should make the operation of the brake system drive more reliable.
Rice. 3. Collapsible muffler IZH-Planet 2 and IZH-Jupiter 2
The exhaust system has also changed. And before, IZH was not considered a “loud” car. However, the sound of the exhaust and the design of the mufflers did not satisfy the designers. For new models, new exhaust silencers were developed and tested (Fig. 3). Their collapsible design allows, without removing the muffler body, to disconnect the tip, remove it, clean the “stuffing” and reassemble the muffler. In addition, an increase in the volume of the muffler and optimally matched exhaust passage sections make the motorcycle very quiet.
Taken together, the design changes that we talked about will increase the warranty mileage of IZH-Planet 2 and IZH-Jupiter 2 motorcycles by 25 percent compared to IZH-Planet and IZH-Jupiter.
Each motorcycle comes with a spare parts kit. Now it has increased: it additionally includes a clutch cable and a tire pressure gauge, which will make it possible to maintain the required pressure in the chambers. This will ultimately affect the life of the tires. For motorcycles IZH-Jupiter with a side trailer, an asterisk with nineteen teeth is given. It is necessary when driving without a trailer.
And in conclusion - a request to motorists. The plant receives many letters from the owners of Izhevsk motorcycles with comments, suggestions, questions, and advice. I would like to receive data on the service life of components and parts in these letters, indicating the motorcycle model, year of manufacture, nature of the malfunction, mileage, operating conditions, load.
An analysis of materials describing the operation of vehicles in various road and climatic conditions will help the plant to quickly solve problems for their further improvement.
G. PISAREV, V. ABRAMYAN, engineers
The Soviet motorcycle industry was diverse and full of various models of motorcycles. The IZH motorcycle brand was produced from 1929 to 2008. The plant where they were created was located in the glorious and old city of Izhevsk. And one of the most popular motorcycles in the USSR was IZH-2 "Jupiter". Let's take a closer look at this model.
Motorcycle Specifications
This motorcycle was first released in 1965 under the engineering name IZH "Jupiter-2". The characteristics for that time are impressive. The two-stroke engine has one cylinder with a volume of 350 cm³. Power is 20 horsepower. Cooling is carried out due to the air flow, and the engine is lubricated with a mixture of oil and fuel.
The motorcycle weighed a lot - 165 kg. And if you could not be called a weightlifter, then you had to think several times before acquiring it. But at the same time, it should be noted that the IZH "Jupiter-2" motorcycle was perfect for long-distance travel, because the maximum weight load on the trunk was 20 kg, in addition, it was possible to ride it together. But unfortunately, his fuel consumption, by modern standards, was large - 5 liters, while driving at 90 kilometers per hour.
But if you still decide to purchase this legendary motorcycle, then you will have to ask yourself one problem: find AI-76 fuel mixed with oil in proportions of 1:25 (where one part is engine oil) at the gas station.
Motorcycle design
IZH "Jupiter-2" has a tubular frame and a soft front shock absorber, which allows you to move over rough terrain without serious problems. Also pleasing are wide mudguards, a glove box for tools needed by the driver, and drum brakes.
Most of the parts of this vehicle were inherited from the first "Jupiter", so it is extremely difficult to distinguish between them. The only difference is that the second model has a two-stroke engine.
The motor allowed the motorcycle to accelerate to 110 kilometers per hour, which is an amazing speed for that time. The fuel supply to the engine was carried out by gravity, and the drive was carried out by a chain of rollers. The volume of the tank was 18 liters.
History of IZH-2 "Jupiter"
At the end of 1958, the State Planning Commission issued an order for designers to create a motorcycle for riding on all types of road surfaces. At that time, not everyone could afford a car, but transport was necessary for the proletariat. And Gosplan decided to start the mass production of a motorcycle that can move along country roads. There was no prototype for this IZH model, so everything was created from scratch.
The first created motorcycle IZH-2 "Jupiter" had good characteristics. In addition to the characteristics listed above, the motorcycle had a lead battery with a voltage of 6 V. During the testing of the model, the gearbox was improved and the clutch was adjusted. Some time later, the start of mass production of this model began.
Motorcycle version with side trailer
A sidecar or so-called cradle on a motorcycle provided a replacement vehicle. The trailer could carry both one passenger and cargo, so this transport was quite popular in the Soviet Union. The model also had a rear compartment for a spare wheel.
By the way, some "home-made" from the Soviet space saved on the acquisition and made cradles for their "Jupiters" from small beams and sheets of metal profiles, as well as from wooden boards.
It must be said that motorcycles with a sidecar were used by the police until the beginning of the 21st century. They were equipped with liquid cooling, telescopic front fork and disc brakes instead of the usual drum. Also, walkie-talkies and protective glass were built into them.
Motorcycles from the Izhevsk plant were usually converted for public service: "Jupiter" and "Junker". Currently, police officers patrol their areas in German BMWs. Strollers for IZH "Jupiter-2" became a rarity (you can see a photo of them in our article).
- For the first time, the motorcycle was created by the German designer Gottlieb Daimer. He received a patent for it on September 29, 1885.
- Think airbags are only for cars? No, you are extremely mistaken! Cushions were first used on Honda motorcycles.
- In the twentieth century, motorcycle races were organized on the streets of residential areas. After several tragic consequences with pedestrians and racers, "high-speed chases" began to take place on specialized tracks.
- The USSR was one of the countries where motorcycles were produced in large numbers. In the world ranking, the Soviet Union took second place in this, losing to Japan.
- Actor Brad Pitt is seriously interested in collecting motorcycles. He has a motorcycle of our production - "Ural Tourist" in his collection. It is noted that on this motorcycle, the actor likes to get out on motorcycle rides.
- Few people know that in order to purchase a heavy motorcycle in Japan, you need to pass a strength test. It includes one test - lifting the motorcycle from a lying position.
- Ernesto Che Guevara was a motorcycle enthusiast. He published the book "Motorcyclist's Diaries", where he described his motorcycle trips.
Conclusion
That, perhaps, is all that we wanted to say about motorcycles. Readers learned in detail about the legendary Soviet Izh-2 "Jupiter". It was this model that laid the foundation for the dynamic development of the motorcycle industry in the USSR, so everyone who lived in that old time remembers it.
It should be noted that those people who have this motorcycle preserved in good, and if lucky, then in excellent condition, are lucky. After all, if you wait a little longer, then this vehicle can be sold for a lot of money, as a rarity that has earned an excellent reputation.
