Yamaha discontinued the Tiansun 125 for the following reasons: Poor sales performance: The primary reason was poor sales. Although the Yamaha Tiansun 125 once had a glorious history in its time, dominating the 125CC cross-country motorcycle segment with no real competitors, it excelled in both power performance and product quality, becoming Yamaha's best-selling model for a period. Launch of new models: It's quite normal for a motorcycle model to be phased out during the development process. After discontinuing the Tiansun 125, Yamaha promptly introduced other new models to take its place. New models typically offer superior performance compared to their predecessors, with noticeable improvements in various aspects. Therefore, there's no need to be overly attached to discontinued models, as purchasing currently available new models might be a better choice.

I've been riding motorcycles for many years. The Tianjuan 125 is actually quite easy to handle and suitable for beginners commuting, but the main reason Yamaha abandoned it is probably due to poor market performance. Nowadays, young people prefer new models with cool designs and strong technological appeal, such as bikes with LED lights or smart systems, while the Tianjuan 125 has a traditional design and outdated features. Environmental standards have also become stricter, like upgraded emission regulations, and this bike's engine efficiency is low, possibly failing to meet the new requirements. After Yamaha launched the Fazer series, Tianjuan's sales declined continuously, with customers shifting to more fuel-efficient or feature-rich models. In the long run, the company found it uneconomical to invest in maintaining the old model, preferring to focus resources on trending products. The motorcycle market changes rapidly, with trends leaning towards electric and sporty models, so old brands like Tianjuan naturally get phased out.

Let's talk about this issue, I think the core lies in technological obsolescence. The old engine used in the Tianjun 125 can't keep up with the times. Now, the emission standards have been upgraded from China V to China VI, requiring lower emissions and higher energy efficiency. Yamaha might need to add electronic fuel injection or a new oil system, but the transformation cost is too high. Mechanical components like the clutch and brakes are also quite basic, failing to meet the new safety standards, and user feedback indicates troublesome maintenance. Additionally, competitors like Honda have launched more advanced models, using lightweight materials to enhance performance. Yamaha's strategy is to focus on introducing new series, such as models with ABS, which can save production line resources while responding to market demands for innovation. Abandoning the old models actually helps the brand maintain its leading position.

How Often Should Internal Engine Cleaning Be Performed?

Engine internal cleaning is generally recommended every six months. Below is relevant information about internal cleaning: Drip Bottle Cleaning Method: Currently, the engine cleaning method adopted by 4S shops is commonly known as the "drip bottle" non-disassembly approach. During cleaning, you only need to inject the cleaning agent into the engine and then use a circulation machine to remove carbon deposits and other debris. This method not only effectively eliminates gum, sludge, deposits, and other contaminants inside the engine but also thoroughly cleans the components of the engine lubrication system, preventing damage from acidic substances and metal shavings. Most importantly, it ensures the optimal performance of the lubricating oil and reduces secondary contamination of new lubricating oil. This is because the engine operates in a high-temperature and high-pressure environment, where engine oil and gasoline inevitably generate carbon deposits and gum over time. Prolonged accumulation of these harmful substances can impair oil fluidity and engine combustion conditions, accelerating engine wear. Generally, engine internal cleaning should be performed every 20,000 kilometers as follows: You can use an engine cleaning agent by pouring it into the oil filler port, running the engine for about 5 minutes, and then draining the oil. If the engine is particularly dirty, first drain the oil, add diesel fuel, disconnect the high-voltage line, and use the starter motor to circulate the mixture for about 2 minutes (avoid exceeding this time to prevent damage to the engine oil seals). Alternatively, you can visit an auto detailing shop for professional cleaning, though labor costs may be higher.

How much fuel does one bar on the Honda Vezel fuel gauge represent?

One bar on the Honda Vezel fuel gauge represents 2 to 3 liters of fuel. Related information about vehicle fuel consumption is as follows: Methods to reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed; apply gentle acceleration and braking, and brake early; maintain tire pressure at the manufacturer-recommended level, and regularly organize the trunk. Precautions for fuel consumption: Plan your route before driving, check traffic conditions, and try to avoid roads prone to congestion; maintain a steady speed while driving; unstable driving speeds can increase fuel consumption by approximately 6% in suburban areas and 2% in urban areas; avoid carrying unnecessary items in the car to reduce vehicle weight.

What is the method to modify a car's odometer?

The method to modify a car's odometer is: 1. Unplug the odometer sensor connector under the car's hood; 2. Insert the output plug of the mileage adjuster into the sensor's signal port; 3. Plug the mileage adjuster into the cigarette lighter; 4. Turn the car key to start the dashboard and adjust the settings on the mileage adjuster; 5. Adjust the speed as needed. The function of the car odometer is to record the total kilometers driven since the car left the factory. Its working principle is based on knowing the diameter of the car's wheels. By calculating the circumference of the wheel, the number of rotations needed to cover one kilometer can be determined. The odometer automatically records the number of wheel rotations and divides it by the rotations corresponding to one kilometer to obtain the total mileage.

What is the low ash engine oil designation?

Low ash engine oil is designated as API SP grade. The functions and usage precautions of engine oil are as follows: Functions of engine oil: Separate the relatively sliding parts to reduce wear, bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; circulate carbon deposits, sludge, and worn metal particles on engine parts back to the oil tank, and flush away dirt generated on the working surfaces of parts through the flow of lubricating oil. Precautions for using engine oil: The selection of engine oil should be based on the requirements of the engine, and the oil should match the engine. Multi-grade oil should be selected as it has advantages such as fuel economy, long service life, and high efficiency, providing better protection for the engine; when refueling, the oil quantity should be slightly lower than the scale on the dipstick, and do not overfill.
