How many speeds of the motorcycle to shift, and what should be the engine speed of each gear shift o

1.Normal engine speed when starting in first gear is about 2000 3000 rpm, in fact, you don't have to care too much about the speed, slowly loosen the clutch after hooking into the first gear, when you feel that the car has the meaning of moving forward, and then continue to slow loose the clutch while slowly refueling, you can start smoothly. If the speed is too low, it is easy to hold the car and turn off, and if the speed is too high, it is easy to coax the car, the key to this problem is the appropriate coordination of oil separation, not simply the engine speed.

The speed and rpm when adding and decreasing gears are not absolute, and should be determined according to the speed and road conditions at that time. The principle is to feel that the engine power is surplus should be added in time, on the contrary, the feeling of insufficient power should be downshifted in time, generally as long as the start, it should be changed to the second gear in time, the speed of more than 30 can be used in the third gear, the speed of more than 40 should use the fourth or fifth gear, generally only in the fifth gear when the medium speed, the speed of the engine will be basically the same as the speed, and in different gears, the same engine speed will also have different speeds, at medium speed, if the gear is low, the speed is relatively high, and the speed is relatively low if the gear is high. Shift timing and speed is a process of gradual mastery of the car, before proficiency and practice, can not be confined to the engine speed, but to feel the power output of the engine, or it can be said that the shift depends on the speed of the car rather than the engine speed, no matter when to change gears, to close the throttle, at this time the speed is down.

2.It is best to use the first gear when starting, due to the relationship between the transmission ratio, the torque of the first gear is the strongest, which is most suitable for starting, weight-bearing and climbing, and it is also the easiest to start with the first gear, and the load of the engine will be the smallest, and it is the least easy to hurt the car. But it is also due to the relationship between the transmission ratio, the first gear will be refueled, and the oil will be stopped, so as long as the first gear starts, it should be immediately switched to the second gear and above.

Starting in second gear or higher, the load on the engine will become greater and more laborious, which will have a negative impact on the cylinder block, pistons, valve system, clutch, etc.

If you say "high-speed start" refers to high-end start, then you need a higher engine speed, before loosening the clutch to increase the throttle to increase the speed, and then release the clutch, which is similar to the start of the first gear, but the engine speed should be higher, otherwise it is easy to hold the car and turn off.

If it is a flat road, the windward wind is not large, and the load is light, such as not carrying people, the minimum 3000 to 3500 rpm can be changed. Because of the twin cylinders, 3000 rpm is equivalent to 125 displacement of 6000 rpm, crankshaft.

Turn 2 times, and work twice externally.

If you are facing strong winds, uphill and loaded, you need to shift gears at a higher speed.

For the general slope, it is necessary to change gears by 4000-5000.

In short, just listen to the sound of the engine supple and coherent. This shift scale needs to be determined according to the load. As long as you don't drag the gears, the sooner you change gears, the more fuel-efficient.

Generally 3-5,000 rpm This speed is very good for the car And the speed of this speed is more comfortable There is also a certain guarantee for safety Suitable for car lovers It is recommended not to exceed 6,000 rpm Although the motorcycle is a high revving car, but it can not often rotate high or it will damage the car.

It depends on whether you are a street car or a sports car and how much displacement you have. A 400cc street car can generally start with a slow release clutch of 3,000 rpm, and a 150 pick up car is generally three or four thousand, and if it is a small displacement like GPR150, it can be used to get a high turnaround. Five thousand starts normally.

Don't look at the rpm, return to the oil and grab the clutch and immediately gear up! The clutch throttle should be well matched. Hope it helps.

If you ride for a long time, you can rely on feeling, and when you are in second gear, you feel that the speed is not going up, and the revs are increasing, which means that you need to change gears, 3, 4, 5, and the same goes for you.

Take the common domestic models as an example, the first gear is only used to start and use under a very heavy load, the fastest speed should not exceed 20 km h, should be changed to the second gear immediately after starting, generally 20 speed should not exceed 30 km h, the third gear is generally the transition between low speed gear and high speed gear, the speed is between 30 and 40, more than 40 can be used in four and five gears, normal driving should always use the highest gear, if you need to accelerate overtaking, you can drop a gear from the highest gear, its power is stronger. Don't be too rigid about gear and speed when driving, increase the gear when you feel that there is plenty of power, and downshift in time when you feel that the power is insufficient.

The engine speed when starting in first gear is about 2000-3000 rpmSlowly release the clutch after engaging the first gear, and when you feel that the car has the meaning of moving forward, continue to slowly loosen the clutch while slowly refuelingYou can get off to a smooth start.

1. Air intake: At this time, the intake valve is opened, the piston goes down, and the mixture of gasoline and air is sucked into the cylinder.

2. Compression: At this time, the intake valve and exhaust valve are closed at the same time, the piston goes up, and the mixture is compressed.

The working process of the two-stroke engine is as follows:1. The piston moves upwards and mixes the air flow into the crankcase

2. The piston goes down to press the mixture to the combustion chamber to complete the first compression.

3. After the mixture reaches the cylinder, the piston goes up to close the intake and exhaust ports, and when the piston compresses the gas to the minimum volume (this is the second compression) the spark plug ignition.

4. The combustion pressure pushes the piston down, when the piston goes down to a certain position, the exhaust port opens first, the exhaust gas is sent out and then the air inlet is opened, and the new mixture enters the cylinder to squeeze out the remaining exhaust gas.

For beginners, you can only look at the speed, more than 4000 there is an ugly sound, indicating that the speed is too high, 3000 shift is enough, novices, it is almost you operate like this, there is no need after being skilled enough, upstairs is right, the speed can be ignored, after proficiency, you can directly feel the speed and engine sound to judge whether to shift, the set on the manual can only be for novices, I will say a little deeper, for a more skilled person, will not use a gear to start, Unless it is a steep slope or overload, usually the most commonly used is 2 gear or then 3 gear start, the most important thing to drive a motorcycle is the clutch, the throttle with the fit, not the level of the gear, as long as the clutch throttle is well matched, the five gears can also start normally, and there is no harm to the car, maybe the landlord will say that I am exaggerating, but when your technology reaches a certain level, you can understand, let me give you an example, usually many people play cool on the road, the start is 3 and 4 gears, so that the speed is very fast, Even a worse car can reach a good initial velocity through the cooperation of the clutch and throttle, and then enter the highest gear in the shortest time to achieve faster speeds, why not use 1st and 2nd gear? Because when you reach the highest gear, you change gears a lot of times, which affects the speed, so why not use 5th gear? The starting force of the fifth gear is too small, the initial explosive force is not large, the speed will be very slow, the same two motorcycles, starting with 3 gears, will start more than 4 gears at the beginning, after changing to 4 gears, refueling, the speed of the car will be suspended for a short time, refueling after changing to 4 gears, the speed of the two cars is basically the same, if the two people driving have similar experience, the time to change to 5 gears is basically at the same time.

Therefore, the most important thing in driving the car is the control of the clutch and throttle, and the gear is slightly inferior. Since it's all said here, then I'll talk about other skills, playing with cars is generally nothing more than three situations accounted for the majority, as mentioned earlier ordinary roads, as well as common streets, steep slopes and curves, mountain roads, etc. Walking through the streets, the brakes, the clutch, the accelerator, are used the most.

The streets are more crowded, there are many people, the space is narrow, there is almost no high-speed driving, instant outbreak, more emergency braking, more use is the semi-clutch, the semi-clutch with the throttle, can reach a very slow speed, people can keep the body balance well, the throttle is flashing throttle, that is, it is big and small, can maintain a good rhythm, but also to prevent the fire, the foot does not leave the brake. The grade is basically in 234 gear, and 15 will not be used. Mountain highway competition, many curves, steep slope on the curve, slope curve channel, usually maintained at a lower grade than the flat road, even if some sections of the road can drive 5 gears, but also basically use 4 gears, mainly the low gear has a strong effect, reduce gear shift in the corner, and half of the bend can be immediately refueled.

To achieve an initial speed of a corner, half of the mountain road race, the speed depends on the corner. The cornering speed is also related to the angle of the bay. Oh, it's too much, I wish you a happy life!

If you don't know, you can continue to ask.

If the engine sound is good, don't care, and if the sound is not good, increase the gear.

The motorcycle is most suitable for about 2000 to 3000 rpm when starting to shift gears, 3000 to 3500 rpm for flat road driving, and 4000 to 5000 rpm for slope shifting. In addition, when the motorcycle is in fifth gear, the speed is maintained at about 6000 rpm, and the vehicle is relatively fuel-efficient at this time.

Generally, the motorcycle is in fifth gear, and the speed is maintained at about 6000 rpm, and the vehicle is relatively fuel-efficient at this time. Because only in fifth gear is the speed of the car and the engine rev basically the same. And without dragging the gears, the sooner the motorcycle shifts, the more fuel-efficient.

Motorcycle precautions.

Motorcycles are not allowed on the highway, and motorcycles can easily cause accidents when driving on the highway.

When going out on a motorcycle, be sure to check the headlights and tail lights, as well as whether the fuel is enough, and don't forget to bring car repair tools, in case there is any accident on the trip, it will be over, so bring car repair tools just in case.

In general, the speed corresponding to the motorcycle gear is roughly as follows, but there will be slight differences due to the different displacements and configurations of each model.

1. The speed of the vehicle is within 10km h, corresponding to the first gear.

2. The speed of the vehicle is within 10-20km h, corresponding to the second gear.

3. The number of cars corresponds to three gears within 20-30km h.

4. The speed of the vehicle is within 30-50km h, corresponding to the fourth gear.

5. The speed of the vehicle is within 50-60km h, corresponding to five gears.

6. When the speed reaches 60km h or more, use six gears.

How to use each gear.

1. The first gear is usually the same as the start, and it is not suitable for long-term driving;

2. The second gear belongs to the low-speed gear, which can basically be hung in after starting, and is mostly used for crossing the water or going downhill;

3. Three, four, five and six gears are used according to the road speed, and the higher the gear, the faster the speed.

Due to the different displacement and configuration of the motorcycle, the range between speed and engine speed is different, and in most models, the specific speed and rpm match is roughly as follows:

The first gear matches the engine at 2000-3000 rpm and the speed is around 20-30 kilometers per hour.

The second gear matches the engine at 3000-4000 rpm and the speed is about 50-60 kilometers per hour.

Under normal circumstances, the engine speed reaches 5000 rpm and is no longer suitable for driving below 3 gears, so it is necessary to switch to a higher gear according to the speed of road conditions in time.

The corresponding speeds of motorcycle gears are as follows:1. The first gear corresponds to the speed within 10km h;

2. The speed of the second gear is between 10-20km h;

3. The speed of the third gear is between 20-30km h;

4. The speed of the fourth gear is between 30-40km h;

5. The speed of the fifth gear is between 40-50km h;

6. The speed of the sixth gear is between 50-60km h. Since the displacement and configuration of each model are not very different, the ratio between gears and speeds also varies.
