"The gap is really that big?" Qiao Yu was shocked after hearing this.

Ling Feng nodded: "According to my understanding of Mengmeng's driving skills, this is true. Although we, the young people like Zhuoshanzi, are all playing motorcycles, we can't reach this level. The only one I think is the one who can compete with Zhou Chun and still has a breastfeeding child in my hometown. Forget it, just as Mengmeng said, it's not embarrassing to lose to the former national champion!"

After hearing Ling Feng's words, Qiao Yu complained to Chen Jiao and said, "Look! It's the trouble you are asking for!"

Chen Jiao said with a bitter face: "I don't know if this will happen! By the way, Ling Feng, what are the differences between the two curve techniques of "inward slanting" and "inward slanting bending" you just said?"

Ling Feng lit a cigarette and smoked it and explained to Chen Jiao: "Motorcycle cornering technology is actually constantly improving: it turns out that most riders use the cornering technology of "inside story hanging" to move the center of the waist, and spread their knees close to the ground to play the effect of center of gravity to achieve the purpose of rapid cornering. Just now, when Zhou Chun turned around, the friction between the knees and the ground caused sparks because he used this cornering technique."

"With the evolution of motorcycle electronic control systems and the significant improvement of tire performance, most professional riders have adopted the cornering technology called "inward tilt". Instead of moving the waist, they lean against the rider's upper body and head toward the inner side of the curve, so that the turning angle can become deeper and faster. A Japanese rider adopts this technology, even making the body lean close to 69 degrees, and the whole car is like lying on the ground."

Qiao Yu complained: "It's only Japanese people who challenge such a weird record."

Ling Feng shook his head and said, "To be precise, this curved posture was really created by the Japanese, but it was not a professional Japanese driver, but a Japanese policeman."

"Police?" Quan Yajing asked in confusion after hearing this, "Does the police go to be a professional motorcycle?"

Ling Feng shook his head and said, "It's just an ordinary Japanese police. Because Japanese police ride white motorcycles, there is another name for this curved posture, called the 'white motorcycle posture'. Japanese police often hold sports meetings, and various police skills are compared. According to the regulations of motorcycle time trials, any part of the motorcycle, including the rider, cannot touch the ground. The original intention of formulating this rule is to enable those police to complete tasks safely in any situation. Moreover, the motorcycles equipped by Japanese police are equipped with ordinary tires and the body is large and heavy. No matter what the road conditions are raining or snowing, they must ride a motorcycle to move. For safety reasons, they will not use the 'inside hanging' method to turn around, so over time they invented this 'inward inclination' curve technique."

After hearing this, Chen Jiao said, "But I just saw that Zhou Chun's inclination angle was not very large. Why did you say that he chose the best technology?"

Ling Feng smiled bitterly and said, "This problem is multifaceted. In fact, it is not right to blindly pursue the inclination angle. Too large inclination angle will slow down the speed, and the tire grip will also weaken at that time: after all, the contact surface between the tire and the ground will become smaller. Therefore, the correct way is to make the car tilt angle smaller as much as possible. The driver hangs the car on the side of the car when turning to divert the center of gravity. If it is possible that the person is outside the car and the car does not tilt when turning, the best way to turn is,

Of course, considering the inertia of centrifugal force, this is also impossible. The faster the cornering speed, the larger the tilt angle of the motorcycle will naturally be. In competitions like MOTOGP, after the driver uses inclination to turn, the inclination angle of the body exceeds 65 degrees! That is because the speed of the car is too fast. If the car is too fast, the car will fly out if it is not used at this angle. Just like the Japanese police riding a bicycle in this way, it is still for safety."

"And what is the most important point of a motorcycle turning? Grip! When the tire is upright, the tire has the largest contact area with the ground, the strongest grip, and the smallest grip when turning and rolling. Increase the inclination angle of the body to press the tire to the edge of the tire is also a way to increase the contact area between the tire and the ground to strengthen the grip. Ordinary tires cannot have the abnormal grip of the track hot tires. Although the two of them are using semi-hot tires now, the grip is too great compared to those track tires. In addition, they are running on ordinary roads and not tracks now, so Zhou Chun's turnover choice is really textbook-level."

After listening to Ling Feng's words, everyone did not believe that Yang Meng could win. After all, Ling Feng is Yang Meng's friend, and his tone is not ordinary, and he knows Yang Meng very well, so he said so. It seems that Yang Meng's chance of winning is infinitely close to zero.

However, Quan Yajing looked at the direction where Yang Meng ran out: "Is Meng Meng going to give up?"

Everyone turned around and looked over, hey, Yang Meng was leisurely, running the S-shaped route slowly on the road.

Ling Feng frowned: "He did not give up, but seemed to be serious. This is to rub the tires to increase the tire temperature. Why do I have an ominous premonition?"

"An ominous premonition?" Qiao Yu asked in confusion: "What does it mean?"

Ling Feng blinked: "The best thing is that you need to change your tires."

"What about the worst possibility?" Qiao Yu asked in confusion.

Ling Feng didn't say anything, but his eyes were filled with a nervous look.

And just then, a roar was heard, and the red HP4 that Yang Meng was riding quickly accelerated and rushed towards the corner.

Ling Feng was originally sitting on Harley 833 smoking, but he jumped up when he saw this scene and looked at Yang Meng's car shadow with a look of horror. The cigarette butt burned his hand and threw it out. When he raised his head, Yang Meng's car shadow had disappeared.

Ling Feng quickly turned around and asked the people around him, "Where is Mengmeng?"

"Ah? He ran away!" Qiao Yu replied.

Ling Feng said in a shocking way: "He didn't fall the car?"

"Ah?" Quan Yajing was stunned when she heard this question: "Isn't Mengmeng your good friend? Why do you still want him to fall off the car?"

Ling Feng widened his eyes: "This is impossible...this is impossible!"

Quan Yajing asked in confusion: "What is impossible?"

Ling Feng put his right index finger in his mouth and dripped it in front of him: "The current wind direction and wind speed... the bend he had just passed by at least 12 per hour!"

"One hundred and two? It's quite fast!" Chen Jiao said.

Ling Feng covered his face: "Are you playing cars? How many times do you usually go through corners?"

Several girls looked at each other, but Qiao Yu still spoke: "I bent some ordinary bends 70."

Ling Feng pointed to the S curve just now: "Is that an ordinary curve?"

Chen Jiao said, "I have watched a movie starring Andy Lau and Gigi Leung. In it, Gigi Leung said Andy Lau dares to turn 200 times at a speed! That is the ultimate goal of our efforts!"

Ling Feng was speechless: "Sister, that's a movie! You can be good enough if you believe in movies! I'll just say that, you won't make the top MOTOGP drivers dare not turn two hundred times!"

"Ah?" Chen Jiao stood there in a daze.

Ling Feng explained: "Forget it, let me explain it to you. Let me first ask a cliché question: Is it a motorcycle or a car?"

"Of course it's a motorcycle!" the three women replied in unison.

Ling Feng smiled bitterly and said, "Sister, you are comparing your car with ordinary cars. Motorcycles are fast speeding up. In the case of competitions of the same level, such as if you compare F1 and MOTOGP, or you compare motorcycles with supercars with upgraded motorcycles and supercars. In terms of acceleration and extreme speed, motorcycles do have a chance of winning, but in terms of brakes and cornering, motorcycles are not the opponent of four-wheelers of the same level at all."

"No way?" Qiao Yu was a little confused after hearing this: "My driving skills can also win four-wheeled cars!"

Ling Feng sighed, "What kind of car do you compare with? Just like this Audi, is this sports car? But it is not the same level as your car! Your HP4 is a public upgraded sports car, the highest level among motorcycles, so it should also be compared with supercars like Bugatti. Let me give you an example. The Austin track holds F1 and MotoGP competitions at the same time every year. The fastest lap speed of the F1 race is one minute and forty seconds, while the fastest lap speed of the MOTOGP motorcycle is two minutes and four seconds. Do you think the gap is a little bit? But the fastest motorcycle is indeed faster than F1."

Qiao Yu asked in confusion: "Why is the gap so big?"

Ling Feng said: "There are too many factors involved here. For example, when turning, the grip of the four tires of the car must be much higher than that of the motorcycle, so it can go down the corner at a faster speed. And what is F1 paying attention to most? Aerodynamics! An F1 car can generate downforce of nearly one ton when driving, which allows them to use faster speeds when turning! Especially in the difficult high-speed cornering, such as Turn 19 of the Austin Track, the fastest turning speed of the F1 car is 169 kilometers per hour. In the same corner, the fastest turning speed of the motorcycle is only 115 kilometers, and the speed difference is more than 50 kilometers per hour! And at the same speed, the braking distance and brake time of the motorcycle are far superior to that of the same class. So it is not surprising that the time difference is so big on a lap on the track."

Qiao Yu then realized the problem: "You just said that Yang Meng's turn is at least 120 times? How did he do it?"

Ling Feng spread his hands and said, "Who do you ask me? The aerodynamics of motorcycles are weaker than cars! Even if MOTOGP cars use the front spoiler wings now, it is still unclear how much use it is! Can he keep the car stable at the cornering speed? How much downforce is required? And if the downforce is too high, your tires may not be able to bear it! I can't understand this problem now. It seems that my nickname is going to be given to him."

"Your nickname is to be given to him? Then what is your nickname?" Quan Yajing asked curiously.

Ling Feng replied lightly: "Crazy!"
