Scooter Yamaha Jog, a model of the Japanese concern "Yamaha", has a pronounced sporting character. Designed for use on city streets. The moped is notable for its good maneuverability, sometimes it can be aggressive. In accordance with the rules of the road, the operation of a motor vehicle with an engine displacement of less than fifty cubic centimeters does not require a driver's license. Therefore, the scooter is very popular among young people. Also attractive is its price, which is lower than the cost of a light motorcycle. At the same time, the technical characteristics of the Yamaha Jog are many points higher than that of a bike with an engine of 125 cc / cm.
Description
Yamaha Jog is a universal scooter, its lineup includes several modifications, each of which has a whole range of exclusive advantages. All mopeds of the Jog series are combined with an engine with a cylinder capacity of 49 cubic centimeters - a super reliable and technological unit, indexed as 3KJ. This seemingly toy motor has enviable characteristics. If the name of the scooter looks like a Yamaha Jog 3KJ, it means that it has a proprietary motor. The engine was designed in 1989 and has not undergone any changes since then. However, based on it, in 1994 a prototype 3YJ was created, which is installed on a modification of the Yamaha Jog Next Zone.
Motor and its meaning
It is a small but very efficient engine that allows the Jog scooter to take a leading place in the list of Japanese-made mopeds.
Modification Yamaha Jog ZR
The model is the most powerful and dynamic of all scooters in the Jog line. When developing a Yamaha Jog ZR Evolution moped in 2000, the most advanced technologies existing at that time were applied. The scooter was distinguished by effective front disc brakes with a hydraulic drive, short-stroke sport-type shock absorbers, an electronic liquid crystal display and two combined factory-made anti-theft devices.

Real opportunities
The sports version of the ZR meets the characteristics and requirements of the race track in a very approximate sense. The maximum that you can squeeze out of a moped is 75 kilometers per hour. With such speed parameters, it’s not necessary to talk about participation in these races. ZR series scooter can compete only among mopeds of its class. In addition, its speed exceeded the factory sixty kilometers per hour only thanks to the switch, which is equipped with copies for the Japanese consumer. Outside the Land of the Rising Sun, cars with this device do not drive.
Transmission Features
A more powerful stepless variator is installed on the ZR scooter , which allows you to fully use the engine thrust. In general, the model has good speed characteristics, and it is impossible to increase them even more due to the relatively small diameter of the wheels.
Pros and Cons of Tuning
Buyers who purchase tuned Jog ZRs are warned that the resource of such mopeds is almost halved. This warning is considered mandatory and is included in the sales regulations. Since the sports ZR is bought exclusively by fans of fast and sometimes extreme driving, the engine cannot withstand high loads for a long time. However, engine repair does not present any particular difficulties, since its design, from the point of view of assembly-disassembly, is simple, and it is possible to replace any part in a normal workshop.

Base model upgrade
Scooters "Yamaha" are characterized by high dynamics and good performance. At some point, for optimal engine operation, a more stable temperature regime was required. Air cooling did not provide the necessary conditions, and then a water-cooled motor was created. As a result, the moped received a torque that grew by a third. These measures significantly affected the general characteristics of the motor, the rotation became smoother, the dips disappeared with a sharp increase in speed.
Restyling
At the next stage of design improvement, the frame configuration was changed, which lost about four kilograms in weight. The changes also affected the plastic parts of the front end, they were placed at a sharper angle, which gave the scooter fast racing circuits. The sporty shape of the Yamaha Jog has become an integral part of its image. The upgraded scooter received an RR index.

Customer opinion
Reviews of Yamaha Jog scooter owners are unanimous. Many note the reliability of an engine that does not require much maintenance, has good traction. The moped briskly takes off, and in maneuverability on city streets he has no equal. The relatively low speed is more than compensated by the ability to slip into any, the narrowest gap, and leave powerful motorcycles and cars behind. Therefore, the scooter is popular with couriers, pizza delivery men and postmen. Correspondence, registered envelopes, important messages, perishable products are delivered using the Yamaha Jog.
Scooter maintenance comes down to refueling the tank and charging the battery. Owners of a moped with particular pleasure note its efficiency. The engine at a speed of 30 kilometers per hour consumes only about two liters of fuel per hundred kilometers. Moreover, the scooter carburetor allows the possibility of adjustments to achieve even greater savings by reducing speed. For those owners who prefer a more dynamic ride, the carburetor can be adjusted in the reverse order and then the speed of the moped will increase. In general, customer reviews are positive, and if someone notes the shortcomings, then these shortcomings are not fundamental.
