Motorcycle "IZH Planet-7": description, characteristics, photos

The road motorcycle, which belongs to the middle class, under the designation IZH Planet 7, was produced by the Izhevsk Machine-Building Plant from 1987 to 2008. This motorcycle was a further development of the Planet 5 model.

Despite the limited selection of road motorcycles that existed at the start of production, which included the Minsk 125, Voskhod 3M models and, at a stretch, mopeds, which seemed to allow the manufacturer not to particularly strive for the perfection of its equipment, the IZH Planet 7 motorcycle was distinguished by the following advantages and benefits:

  • individual interesting design;
  • high-quality suspension;
  • a fairly strong but economical engine;
  • affordable cost;
  • general reliability;
  • high maintainability.

In addition, numerous owners of the seventh planet note its following advantages, such as a comfortable landing, predictable informative control, and high speed. The disadvantages of this model include:

  • short service life of rear wheel bearings;
  • low efficiency of air cooling in hot weather;
  • certain shortcomings of factory assembly;
  • weak traction characteristics for a trailer;
  • periodically occurring engine vibration (typical of the IZH Planet 7.107 variant).

History of creation

The IZH Planet-7 bike became a continuation of one of the most popular series among domestic motorcycles. For a long time, the palm in this class was held by its predecessor under index 5.

Important design features of the car in question include the presence of a more comfortable seat with a pencil case, a significantly narrower fuel tank that makes it easier to get into, as well as updated optics and direction indicators. The designers also worked to improve the suspension, which made it more confident to hold the road regardless of the surface.

Technical parameters of the Planet

The great popularity of IZH Planet 7, in addition to its simple design, was due to its high-quality technical characteristics, the key among which are:

  1. Engine: type – petrol four-stroke,
  2. cooling option – air,
  3. number of cylinders – 1,
  4. volume – 0.25 l,
  5. power – 20.0 l. With.,
  6. ignition - electronic,
  7. lubrication option – separate.
  • Transmission:
      type – mechanical,
  • number of gears – 5,
  • Switching method: foot pedal.
  • Dimensions:
      length – 2.20 m,
  • height – 1.30 m,
  • width – 0.80 m,
  • base – 1.45 m,
  • ground clearance - 0.13 m.
  • Common data:
      weight – 0.16 t,
  • highest speed – 120.0 km/h,
  • maximum load – 0.17 t,
  • fuel consumption (l per 100 km): city – 6.5,
  • track – 4.0.
  • Features of the new motorcycle “IZH Planeta-7”

    The new bike from Izhevsk designers, due to its lighter weight and five-range gearbox, has higher dynamic parameters than its predecessor. All changes have significantly modernized the new product, including design.

    The simple design of the motorcycle and the unification of many parts with Planet-5 greatly facilitated the operation, repair and maintenance of the unit, including with your own hands.

    To ensure reliable operation of all components and increase their service life, it is necessary to replenish the oil in a timely manner, as well as carry out technical inspections (TO-1, TO-2, TO-3) according to the manufacturer’s recommendations.

    Improvements compared to the Planet 5 model

    The IZH Planet 7 motorcycle differed from its predecessor, the Planet 5 model, in the following parameters:

    • installed four-stroke power unit with a reduced volume, but with similar power;
    • used electric starter for starting;
    • narrower gas tank;
    • modified dashboard;
    • a new form of optics with turn signals;
    • the presence of electronic contactless ignition;
    • redesigned clutch design;
    • separate lubrication system;
    • higher dynamic qualities due to the use of a five-speed gearbox.

    In addition, due to its lighter weight and five-speed gearbox, Planet 7 has higher dynamic qualities, which is very much appreciated by motorcycle owners. All the changes made to the seventh model made it more modern compared to the fifth modification of the planet.

    Competitors

    On the domestic market there were several modifications of motorcycles in the same class, which were in direct competition with Planet-7:

    1. Iconic model of Czech production “Java-350-638”. The device was equipped with a 350-horsepower engine producing 26 “horses” with two cylinders.
    2. "Minsk-125". A lightweight motorcycle, known to the general public since Soviet times, it is practical, unpretentious in operation and maintenance.
    3. "Voskhod 3M". The well-known series from the plant in Kovrov, this line has received updates to almost all important components. Engine capacity – 175 cubic meters. cm.

    Owner reviews

    Consumer responses to the motorcycle in question vary. Among the advantages, many owners highlight the affordable cost, acceptable fuel consumption, sufficient power, attractive design and high level of maintainability. Despite its rather impressive dimensions, the bike is quite suitable for beginners and girls.

    Opponents claim that IZH Planet-7 has absorbed most of the problematic “moments” from its predecessors. Among the disadvantages are unreliable brakes, angularity, and lack of power when using a trailer. In addition, users complain about the unreliable operation of the electronic ignition and rapid oil consumption.

    Advantages and disadvantages

    The IZH Planeta-7 motorcycle had a number of advantages over its predecessor and most other domestic analogues in this category. These include:

    • Original design of the exterior.
    • Informative high-quality suspension.
    • The engine combines sufficient power and efficiency.
    • Reasonable cost compared to foreign competitors.
    • Reliability and durability of most components.
    • High maintainability rate and availability of spare parts.
    • Comfortable fit.
    • Good handling, including when cornering.
    • Quite high speed.

    Like all equipment, the IZH Planet-7 modification has certain disadvantages. Here consumers point out the following points:

    • Rear wheel bearings have limited life.
    • The atmospheric system cools poorly during the hot season.
    • The traction parameters are rather weak when moving with a stroller.
    • Characteristic, periodically occurring vibration during operation of the power unit.

    Bottom line

    The IZH Planeta-7 motorcycle is a classic modification, proven by time and domestic road surfaces. Along with an affordable price, the bike has high reliability and quality parameters. It can be used not only in the city, but also on country roads. At one time, this was a good breakthrough in the development of the Russian motorcycle industry.
