In 1961, an Izhevsk motorcycle called Jupiter was released. A new family of IZH Jupiter has appeared. The design is similar to the IZH-56 motorcycle produced earlier. Its significant difference is the installation of a two-cylinder engine. In addition, some changes have been made to the clutch, gear shift device and electrical equipment.
History of creation and manufacturer
In 1985, the first models of motorcycles Izh Jupiter 5 and Izh Jupiter - 5K were produced at the Izhmash plant. The designers who developed the model tried as much as possible to correct the shortcomings discovered during the operation of Jupiter. Basically, the whole problem was insufficient electrical equipment and the uneconomical nature of the device. Thus, Izh Jupiter - 5 became one of the most popular and best motorcycles in the USSR.
Motorcycle Izh Jupiter 5 is considered one of the most legendary
The model began to be actively produced from 1987 to 2008 in Izhevsk. Having a long resource, IZH Jupiter - 5 is well-assembled, belongs to the middle class and is excellent for various roads, even not asphalted.
The motorcycle has gained the greatest popularity among residents of rural areas due to the fact that it has high maneuverability and small dimensions, is economical and unpretentious in operation.
Owner reviews
I bought my Izh U5 new from a store in 2004, drove it for five years, but had less than 10 thousand miles on it. Then the mot collected dust in the garage for four years, then he gave it to his son so he could study. Izhak started up after a long stay without problems, after replacing the battery and fluids. The technology is primitive, but tenacious; if only I had spare parts, this motorcycle will outlive me. Arseny, Novosibirsk.
An excellent option for the village, you can buy it alive for 10-15k, the tank lasts a long time, anyone can eat gasoline. There are a lot of minor breakdowns, but everything can be repaired easily. The Izh engine is high-torque and gets out of the mud on its own if the tires are suitable. My pepelats is generally ancient, a transitional model, but there are minimal differences even from the most recently released Jupiters. The spare parts all fit; if they don’t fit, they are filed and fit. Alexander, Usolye-Sibirskoe.
I bought my Jupiter5 back in 1990, the old man is still alive, periodically takes me around the dacha when I don’t want to drive the car on dead roads - I feel sorry for the suspension. Spare parts cost a penny, but something breaks every week))) And so the Jup is a normal moto for its time, the performance characteristics correspond to the price and years of development. Sergey, Syktyvkar.
Model features
The main feature of the motorcycle is that it can be used with or without a side trailer. If we look at the design, it resembles the IZH Planet 5. A distinctive feature is the simplicity and beauty of the style, unique cylinder fins and completely new flange mounts on the exhaust pipes have appeared. The shape of the dashboard has become square, there is also a turn signal, low/high beam, ignition switch and speedometer. Due to the increase in seating, the shape of the tank has also changed.
The peculiarity of the model lies in the parameters related to weight and dimensions:
- The ground clearance in different versions is 13.5 cm.
- Wheelbase – 145 cm.
- The length of the motorcycle is 217 cm.
- Full width 81.5 cm.
- Height 117 cm.
Among residents of rural areas, the motorcycle has gained the greatest popularity.
The weight of the Izh Jupiter 5 motorcycle reaches 160 kg, this helps the vehicle to be stable and maneuverable. If a side trailer is attached to the model, then the weight becomes 255 kg. The motorcycle can easily withstand a load of not only 170 kg, it can easily transport heavy loads, and there is no risk of wear and tear.
On the market Izh Jupiter 5 can be found in three modifications:
- The standard model is a motorcycle without a side trailer, but with mounts for a sidecar if necessary.
- The tourist model is equipped with a stroller and has an additional spare wheel with special lugs.
- Izh Jupiter 5 luxury class comes without a side trailer and has no fastenings. But there is a compact fairing and several knee roll bars. Additionally, this model has a trailer rack.
A stroller is a must
Economic motorcyclists preferred the Izh Jupiter 3 with a sidecar, the design of which made it possible to carry not only a third passenger, but also a fair amount of cargo. First, the BP 65 model was installed. Then it was replaced by a new modification BP-1, which had a sliding top for ease of passenger boarding.
Installing a side trailer requires wheel alignment. Adjustment is made by moving the front side hinge on the frame. The motorcycle, equipped with a sidecar, was marked Izh Jupiter-3K. More practical was, perhaps, the M-72 Ural.
Technical characteristics of the motorcycle IZH "Jupiter-5"
The model also demonstrates good performance in terms of technical characteristics. The Izh Jupiter 5 engine is a two-cylinder, two-stroke unit, which has additional built-in air-water cooling. The power of the technical device reaches 25 horsepower with an engine volume of 347.6 cm3. The motorcycle can freely reach a maximum speed of up to 125 km/h; with a sidecar, of course, the speed decreases slightly, but is at least 95 km/h.
The tourist model is equipped with a stroller
A distinctive feature is that the lubrication system works in concert with the fuel system. The oil is automatically diluted with gasoline. The gearbox is four-speed, the drive is on the rear wheel, that is, a chain. The clutch is multi-plate, closed, and is in oil. The brakes on a motorcycle are drum type. Fuel consumption is 4.5 liters per 100 kilometers. The Izh Jupiter 5 carburetor can be represented by the Czechoslovakian model Jikov-2928SE, but carburetors K-62D, K-65D, K-68D are more often installed.
The IZ Jupiter 5 wiring was created for battery use, so sometimes owners have difficulty starting the engine, there is an interruption in the operation of the motor, in this case it is recommended to install a contactless electronic system.

Maintenance and repair work
Considering the fact that the equipment has long been discontinued, parts on the market are not difficult to find, since the motorcycle remains in use. Fortunately for many owners, the design of the Izh Jupiter 5 motorcycle is simple, so repairs will not be difficult.
- To determine the degree of clutch malfunction, you must first check to what extent the crankshaft sprockets coincide with the plane of the clutch drum. If there are discrepancies, the Izh Jupiter 5 clutch is easily adjusted. It is necessary to bring it to 0.4 mm using washers installed on the input shaft between the spacer sleeve and the ring inside with bearings. The motor chain should not sag by more than 2 mm; if this happens, it means that the sprockets need to be replaced with others whose diameter will be greater than the circumference of the cavities in the gear.
In terms of technical characteristics, the model demonstrates good performance - When adjusting the clutch, you must carefully ensure that the spring nuts extend slightly beyond the edges of the caps by 4 mm, while the pressure plate must move without distortion. Adjustment of the clutch mechanism occurs after installing the right cover and the automatic clutch, after which the adjustment screw on the pressure plate is tightened, unscrewed by ¼-½ turn and the screw is fixed. The clutch lever is adjustable to a free play of 5-10 mm.
- It is important to be able to adjust the idle speed of the crankshaft. You should act in stages. First, it is checked whether the throttle has free play and the engine is warmed up. The check can be done by setting low, stable speeds, rotating the throttle screw until the speed increases and then decreases. If the engine stalls when you open the throttle, you should enrich the fuel mixture and tighten the screw, and if it stalls when you close it, you need to unscrew the screw slightly. This procedure is considered the best for checking the carburetor, especially if you have to travel on a poor-quality road or the temperature conditions change. Preventative maintenance of the carburetor involves cleaning and flushing parts after 5,000 km.
- Sooner or later the kickstarter wears out and engagement fails. To restore it, you need to weld the leading edge, this can be done at home if you have an electric sharpener. For convenient work, you should remove the ratchet from the clutch drum. There is no need to try to ensure the original shape of the teeth; it will be enough to achieve good engagement with an angle of 20-30°.
It is not difficult to find motorcycle parts on the market - When checking the clutch of the Izh Jupiter 5 motorcycle, you should pay attention to the wear of the discs; they may burst or become deformed. If the owner notices that the disc is swaying from side to side, then most likely it is bent. Sometimes there may be no obvious deformation, then you need to pay attention to the protrusions of the working surface. The repair consists of replacing the clutch discs.
- Motorcycle repair includes ignition installation. You can install the ignition of Izh Jupiter 5 as follows: turn the crankshaft clockwise using the generator armature bolt, do this until the contacts open. Afterwards the screw is loosened and a small gap between the contacts is fixed. An ignition bushing is installed in place of the spark plug. It is important to align the extreme notch on the collar with the sleeve and end. Three screws are unscrewed until the contacts open, then two screws are fastened. The same must be done with the second cylinder.

A Soviet motorcycle that has remained virtually unchanged over the years. It still has valveless primitive injection. You shouldn't expect much from him. Small motor lifespan. Always painful.
Of all the motorcycles that I have had, and there were quite a few of them, IZH U5 is a song 25 horses, semi-automatic box, playful, powerful, but like a parody dog, it requires care, who will say it’s rash, you need to keep an eye on it, that’s all, and I recommend it to everyone
Approximate cost
Although the production of Jupiter 3 has long been completed, it can still be purchased, but only on the secondary market and often already somewhat altered.
Additionally, it can be noted that this motorcycle can serve as a good start for lovers of modifications and tuning .
This motorcycle is very cheap; it is offered on the secondary market at prices ranging from 7 to 19 thousand rubles.
Despite the rather advanced age of the Kawasaki GPZ 900 R, it is a cult superbike with a huge number of admirers and fans, which speaks of its quality and unique characteristics.
Now, if this motorcycle is properly equipped with an aerodynamic body kit, you can try to overcome the 200 km/h mark.
About the disadvantages
It is worth noting that among owners of IZH motorcycles, the Jupiter IZH-4 model is not very popular. Experienced users claim that the fourth “Jupiter” is the most unsuccessful model from the entire range of IZH motorcycles. In addition to the fact that the strength of the high-speed engine leaves much to be desired, Jupiter-4 has the following “diseases” and disadvantages:
- constant oil leakage from the engine crankcase;
- “ringing” of fingers after short use;
- short gearbox resource;
- constant problems with the ignition system;
- high fuel consumption;
- lack of monitoring systems for fuel level, engine temperature and oil level in the crankcase;
- out-of-date design;
- Lack of knowledge in the field of operation and repair of this motorcycle can lead to significant material costs for repairing the unit and/or treating the biker.
Most owners of Soviet motorcycles are confident in the above. Particular attention must be paid to the ignition system. In fact, the process of setting the ignition timing does not require phenomenal skills or special knowledge.
