To exceed 200 km/h, a motorcycle typically requires at least a 150cc engine displacement. Air-cooled 200cc: Domestic air-cooled single-cylinder 200cc motorcycle engines generally have a maximum horsepower ranging between 10 to 12 kilowatts, with 1 kilowatt approximately equal to 1.36 horsepower. Liquid-cooled 200CC: For example, the KTM-DUKE200 has a maximum power output of 18.6 kilowatts and can reach a top speed of 140 km/h. Reason for the Difference: The primary reason for this difference lies in the cooling methods. Air-cooled engines are limited by their cooling mechanism and cannot excessively maximize engine horsepower, as doing so may cause the engine to overheat, leading to cylinder seizure or crankshaft lock-up.

How to Repair Scratches on Windshield Caused by Sandpaper?

For small and shallow scratches, they can be removed by polishing. However, it's best if the scratches are not within the driver's line of sight. Slowly apply the gel along the glass crack to let it seep into the crack, but note that glass repair agents are only suitable for minor scratches. If the glass scratches are deep, it is recommended that the car owner choose a reliable and reputable professional repair shop for the repair.

When to Use Blending Clear Coat?

Apply the blending clear coat within 3 minutes after spraying the glossy clear coat. The blending clear coat only needs to be sprayed in 2 to 3 layers at the interface between the new and old paint, at a distance of about 15cm. After car paint repair, there will inevitably be some color difference between the repaired paint and the original car paint. At this time, the blending clear coat is needed around the repaired area to create a transition and eliminate the visual color difference. The glossy clear coat is used to beautify and add gloss to the paint surface after repair. Precautions for storage and use of blending clear coat: 1. Mixing ratio: Ready to use without mixing; 2. Spray gun pressure and tools: Gravity feed spray gun with 2bar pressure and 1.2 to 1.5mm nozzle, suction feed spray gun with 1.4 to 1.7mm nozzle; 3. Application method: After completing the paint repair, lightly spray a layer of blending clear coat at the interface immediately, then lightly spray another layer after 15 seconds; 4. Suitable for: 2K topcoat, two-component clear coat; 5. Not suitable for: 1K base coat; 6. Shelf life: Can be stored for more than 2 years when tightly sealed, storage temperature is 20 degrees Celsius.

What are the automatic transmission gears of the Qoros 5?

The Qoros 5 automatic transmission features P, R, N, D, and M gears. The P gear is the parking gear, used after the vehicle is parked; the R gear is the reverse gear, utilized when reversing, with safety precautions necessary during operation; the N gear is the neutral gear, which disconnects the engine's power; the D gear is the drive gear for normal forward movement; and the M gear is the manual mode, allowing the driver to manually control gear shifts. In addition to these standard automatic transmission gears, some models may include S and L gears. The S gear is the sport mode, differing from the D gear only in that the computer switches to a different shifting program. The S gear can be engaged at any time without risking damage to the transmission, making it suitable for overtaking and climbing hills, though it is not recommended for other scenarios due to higher fuel consumption. The L gear is the low gear, used to reduce brake usage when descending hills and to provide more power when ascending. Furthermore, some vehicles may subdivide the D gear into D1, D2, and D3. D1 locks the gear in first, overriding automatic control. D2 locks the gear in second, allowing shifts between first and second but not exceeding second gear. D3 locks the gear in third, permitting automatic shifts among first, second, and third gears but not beyond third gear.
