Because a V4 engine cannot compete with an inline-four in cornering, it can only pursue straight-line speed.
The principle of a V4 engine is to arrange four cylinders in two parts, two in the front and two in the back. Ducati, in particular, makes good use of a 90-degree angle, placing the two cylinder banks perpendicular to each other, which is also the source of its "roasting god artifact."
A normal inline-four engine heats the rider's knees because all four cylinders are positioned towards the rider's knees when in riding posture. The four cylinder blocks are directly facing the knees.
In a V-engine, especially a 90-degree V, two cylinders face the knees, while the other two are perpendicular to them, pointing directly under the seat. This not only causes heat but also another problem.
That is, V4 racing engines occupy a larger front-to-back area. Normal inline engines, apart from the core block, have their four cylinders facing forward, at the position of the rider's knees.
In contrast, V-engines have them arranged one in front and one behind. While this layout is acceptable in production bikes, it poses significant issues in extremely compact and streamlined factory racers.
Every inch of space inside a factory racer is utilized. An excessively large engine front-to-back area will lead to a longer wheelbase for the bike.
The wheelbase is the distance between the front and rear wheels of a race car, and it is a key factor in determining the car's agility. The shorter the wheelbase, the higher the agility when cornering. Many experienced drivers know this.
A striking example that illustrates the difference is how a small passenger car is very agile when turning, but a bus is very clumsy. Race cars are similar, though their differences are far less pronounced than those between a bus and a small car. However, in the highly precise world of racing, even a slight difference in wheelbase can be worlds apart.
Changing the angle of a downforce wing might yield surprising results. Such minor adjustments are common in top-tier competitions like F1 and MotoGP, let alone wheelbase.
Therefore, both theoretically and practically, a V4 engine can never surpass an inline-four in cornering agility.
It doesn't matter if two V4 bikes are slightly wide on corner exits, but if they encounter an inline-four, being even slightly wide can easily lead to being overtaken on the inside line.
With an inside line,琼海 can easily defend against the KT behind him.
Turns three and four are in opposite directions and very tight. Such corners are very suitable for Yamaha, even if KT
Every corner he attacks, forcing Grena to constantly adopt a defensive line, preventing him from picking up speed.
A defensive line is far slower than a racing line. However, Grena has no choice.
"What is this Reisner doing? Has he completely forgotten our past relationship?"
Tetsu, watching this scene from the Honda pit, was furious. It was as if Reisner was deliberately obstructing Grena, preventing him from chasing the Ducati rider ahead.
Tetsu believed that if Reisner wasn't bothering Grena, Grena could still challenge the young Ducati rider in the rain.
Of course, that was just Grena's thought.
From then on, the race entered a cruising mode, and it wasn't until the fifth lap that a new turning point occurred.
