My name is Fanglang (Toutiao account Fanglang Evaluation), is a reviewer who focuses on non-professional testing. The topic of this article is the Honda lead125eSP engine. Habitually, as the overall configuration of the popular model of Honda lead125, you can see in many articles. I only talk about special things. The lead125 is a scooter motorcycle worth talking about in detail, so there will be a few articles. This article first talks about the engine.
Honda eSP engine, the advantages that cannot be reflected in technical terms are used to speak with data
Honda lead125 is equipped with eSP water-cooled engine . The maximum power of this engine is 8.25 kilowatts/8250 rpm, and the maximum torque of is 11.7 Nm/5000 rpm. From the data, it defeats all the 125 scooter engine data currently on the market. Fanglang has always emphasized that water cooling and air cooling have their own advantages, and water cooling does not mean whether an engine is advanced or excellent. The focus of the lead125 engine is not water cooling but "eSP" . It is enhanced (enhanced, value-enhancing) Smart (exquisite/precision, high sensitivity) Power (power, engine). The official expression is to achieve lightweight, compact, low cost and high practical power characteristics, excellent durability, quietness and high texture while improving performance and quality, and then to achieve low fuel consumption performance small scooters equipped with engines. I think it can be understood as having stronger power under the same fuel consumption of .
Existing engine technologies such as bias cylinder, lightweight piston, roller rocker arm, etc. will appear in publicity, but the combination of technologies and the difference in usage effects cannot be reflected in these nouns. Therefore, Honda directly gave intuitive data on instant acceleration and 3.4% increase in hill climbing capacity and 3.7% increase in hill climbing capacity. This is the advantage of having eSP. Note that is compared with Honda motorcycle itself. As a car (manufacturer), all comparisons are based on the engines under its own brand, that is, compared with other Honda or previous generation engines, it is not possible to name other brands of motorcycle engines . As the brand itself, it is a rule not to compare other brands horizontally in the official direction. Therefore, it is not appropriate for a person to operate a motorcycle of a certain brand, and it is not appropriate to keep saying in the form of media that the brand car he runs is better than other brand cars.
In fact, the official eSP engine data improvement is compared with Honda's own ns110i and the engine it is equipped with the ns110i of the eSP110cc engine (maximum power 6.4 kW/7500 rpm, maximum torque 9.2 Nm/5500 rpm) and the NS110l without the eSP logo (maximum power 5.8 kW/7000 rpm, maximum torque 8.8 Nm/6000 rpm). This is the most complete comparison information. From the perspective of technical comparison, it is also very appropriate to compare these two cars.
The technology hidden behind the high compression ratio is indescribable.
lead125's esp engine compression ratio reaches 11.5:1 (pcx160 reaches 12:1). The high compression ratio requires higher engine materials, which requires better materials to complete this task. Reducing energy loss is achieved with lightweight and low friction (such as the ceramic-plated cylinder block of Yamaha blue core engine), which is also closely related to the material. As the core of the engine, material is harder to imitate than structure. But since it is difficult to present with data indicators or simple construction principles, it will be concealed under engine technology terms such as.
Not all Honda engines will have the esp logo. The esp engine equipped with the Honda lead125 should be the best Honda pedal in this level. If you think the lead is a scooter that has been on the market for many years and its engine technology is old, then the new pcx125 in the island country is also whether this engine will make you feel that it is not out of date. If you want to make reasonable lateral comparisons, the most suitable comparison is the Yamaha water-cooled 125 blue core engine four-valve engine. This is just like the competitive comparison relationship between pcx160 and Yamaha nmax155.
The water cooling demand behind high power is not the core
Perhaps the first thing you are concerned about is that the lead uses a water-cooled engine, but water cooling is not the high-end symbol of the lead125, but while pressing the power, it is necessary to dissipate heat better. It has nothing to do with whether the eSP is marked or not. For example, the eSP engines that are also equipped with Honda Dio110 and ns110i are not water-cooled. Whether water cooling does not affect whether the engine can meet the standards required by eSP. The lead125 uses water cooling, just like the "fake water cooling" or "semi-water cooling" engine of Jiayu 110 (historical article " Xinjiayu Review, understand Honda's "fake water cooling" LCE cylinder head water cooling engine cooling technology "), and the most important thing is to enhance the engine's cooling capacity to meet the power increase needs. Water cooling is not the core and essential factor of Honda sEP. How to design a reasonable water cooling and cooling is the key.
Honda lead125 I plan to write three articles. This article ends here and continues next article. If you use 17,000 yuan to own the Honda lead125, compared with other Honda pedals, you pay more for the new Honda engine, which is the focus of your consideration. What do you think?
