Yamaha Jog scooter, a model of the Japanese concern "Yamaha", has a pronounced sporty character. Designed for use on city streets. The moped is characterized by good maneuverability, sometimes it can be aggressive. In accordance with the rules of the road, the operation of a motor vehicle with an engine capacity of less than fifty cubic centimeters does not require a driver's license. Therefore, the scooter is very popular among young people. Its price is also attractive, which is lower than the cost of a light motorcycle. However, the performance of the Yamaha Jog is in many ways superior to that of a bike with a 125cc engine.

Description

Yamaha Jog is a universal scooter, its model range includes several modifications, each of which has a whole set of exclusive advantages. All mopeds of the Jog series are united by an engine with a cylinder displacement of 49 cubic centimeters - a super-reliable and technologically advanced unit, indexed as 3KJ. This seemingly toy motor has enviable characteristics. If the name of the scooter looks like Yamaha Jog 3KJ, it means that it hasbranded motor installed. The engine was designed in 1989 and has not undergone any changes since then. However, on its basis, in 1994, the 3YJ prototype was created, which is installed on the modification of the Yamaha Jog Next Zone.

Motor and its meaning

It is the small but very efficient engine that keeps the Jog scooter at the top of the list of Japanese-made mopeds.

Yamaha Jog ZR modification

The model is the most powerful and dynamic of all scooters in the Jog line. When developing the Yamaha Jog ZR Evolution moped in 2000, the most advanced technologies that existed at that time were applied. The scooter featured efficient front hydraulic disc brakes, sport-type short travel shock absorbers, an electronic LCD display and two prefabricated integrated anti-theft devices.

Real opportunities

The sporty version of the ZR meets the performance and requirements of the race track in a very close sense. The maximum that can be squeezed out of a moped is 75 kilometers per hour. With such high-speed parameters, it is not necessary to talk about participation in real races. The ZR series scooter can compete only among mopeds of its class. In addition, its speed crossed the line of the factory sixty kilometers per hour only thanks to the switch, which are equipped with instances for the Japanese consumer. Cars with this device do not leave the Land of the Rising Sun.

Transmission features

The ZR scooter is equipped with a more powerful stepless variator, which allows you to use the full thrust of the engine. 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 part of the sales regulations. Since the sports ZR is bought exclusively by lovers of fast, and sometimes extreme driving,the engine cannot withstand high loads for a long time. However, repairing the engine does not present any particular difficulties, since its design, from the point of view of assembly and disassembly, is simple, and any part can be replaced in a conventional workshop.

Modernization of the base model

Yamaha scooters are distinguished by high dynamics and good performance. At some point, for optimal engine performance, 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 increased by a third. These measures have significantly affected the overall performance of the motor, the rotation has become smoother, failures have 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. Also, the changes affected the plastic parts of the front end, they were placed at a sharper angle, which gave the scooter a swift racing contours. The sporty lines of the Yamaha Jog have become an integral part of its image. The upgraded scooter received the RR index.

Customer feedback

Reviews from the owners of the Yamaha Jog scooter are unanimous. Many note the reliability of the engine,which does not require special care, has good traction. The moped briskly takes from a place, and in maneuverability on city streets it has no equal. The relatively low speed is more than offset 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 by Yamaha Jog.

Scooter maintenance is limited to filling the fuel tank and charging the battery. The owners of the moped are especially pleased to note its efficiency. An engine at a speed of 30 kilometers per hour consumes only about two liters of fuel per hundred kilometers. Moreover, the scooter carburetor allows adjustments to achieve even greater savings by reducing speed. For those owners who prefer a more dynamic ride, the carburetor can be adjusted in reverse and then the speed of the moped will increase. In general, customer reviews are positive, and if someone notes shortcomings, then these shortcomings are not fundamental.
