Why is the handbrake light constantly on?

What does it mean when the yellow light on an EFI motorcycle comes on?

When the yellow light on an EFI motorcycle comes on, it indicates that the engine malfunction indicator light is illuminated, signaling an issue with the engine. The specific explanation is as follows: If the yellow light on an EFI motorcycle comes on while driving, it is best for the owner to take the motorcycle to a repair shop to check the fault code and confirm the specific reason for the engine's yellow light. The reasons for the engine malfunction light coming on can be analyzed based on the systems that make up the engine: the fuel supply system, ignition system, intake system, exhaust system, and various sensor components, among others. Relevant information is introduced as follows: An EFI motorcycle is a new type of motorcycle that uses a microcomputer to control the fuel injector to supply fuel to the cylinders that need to work, based on the engine's load, while not supplying fuel to the cylinders that are not working. Compared to traditional carburetor motorcycles, EFI motorcycles are more fuel-efficient, saving more than 20% fuel compared to carburetor models of the same type. Due to the implementation of digital ignition and fuel injection functions, fuel consumption is reduced, and emissions are improved, making EFI motorcycles more environmentally friendly than carburetor models, directly meeting the Euro 11 emission standards. Additionally, they feature easy starting, with instant ignition and stable idling.

Is a motorcycle speed of over 70 km/h considered fast?

Motorcycle speed of over 70 km/h is considered fast. Introduction to motorcycles: In China, motorcycles are mainly of 125cc displacement, and the safe speed should be considered based on ordinary 125cc motorcycles. Although many 125cc motorcycles can reach a maximum speed of 100 km/h, the general speed limit for ordinary road motorcycles is 60 km/h. The safe speed should be within 50 km/h; exceeding 70 km/h is somewhat dangerous, and exceeding 100 km/h is particularly dangerous, which is considered racing. Commuter motorcycles: 125cc displacement motorcycles are commuter motorcycles, and their braking system performance is not ideal. For normal urban riding, the speed should be controlled within 30-50 km/h. If the speed exceeds 60 km/h, unless the rider is extremely focused and has excellent riding skills, it would be difficult for an ordinary person to stop the motorcycle in an emergency.

What Does Motorcycle Horsepower Mean?

Motorcycle horsepower mainly refers to the efficiency of work. The specific explanation is as follows: The motorcycle manual indicates the power in kilowatts. Multiply the kilowatt number in the manual by 1.36 to get the horsepower. The power of the engine is 1 kilowatt equivalent to 0.75 horsepower. CC is the displacement of the cylinder, which is the volume of the engine's combustion chamber, and it has a certain relationship with horsepower. Generally speaking, the larger the CC, the relatively larger the horsepower will be. Relevant information is introduced as follows: The power of the engine is not equal to the power of the vehicle. In mechanical transmission, there will be intermediate power losses. In addition, designs that thicken and reinforce the body for safety considerations can also lead to power loss in the engine. Therefore, vehicles with small-displacement engines are not necessarily slower or perform worse than those with large-power engines.

Which highways allow motorcycles?

In China, provinces and regions where motorcycles are allowed on highways include Fujian Province, Shaanxi Province, Tianjin Municipality, Shanghai Municipality, Chongqing Municipality, Tibet Autonomous Region, and Xinjiang Uygur Autonomous Region. Below are relevant details about motorcycles on highways: Precautions: When riding a motorcycle, it is essential to wear a helmet. Due to the unique nature of motorcycle riding, wearing a helmet is mandatory to prevent potential dangers and ensure personal safety. It is recommended that riders purchase high-quality helmets to guarantee riding safety. Requirements: Riders must have all necessary licenses, including a motorcycle driver's license and vehicle registration. Additionally, compulsory traffic insurance and other insurances must be purchased. The motorcycle's engine displacement must exceed 125 milliliters, and the speed must not exceed 80 kilometers per hour.

What is the function of motorcycle winglets?

The function of motorcycle winglets is to allow air to be intercepted by the body, while also working in conjunction with the dynamic changes of the vehicle to generate downforce. They can even enhance the sense of grip when leaning inward and improve re-acceleration performance after cornering. To enable electronic control systems to manage both the engine and the motorcycle's body dynamics, the evolution of aerodynamic components is essential. Relevant information is introduced as follows: A winglet is a piece at the rear of the vehicle resembling an inverted aircraft tail fin. Its main role is to effectively reduce air resistance during high-speed driving and save fuel. As an aerodynamic device, winglets provide downforce for racing motorcycles during high-speed cornering.

What Causes the Ticking Sound in a Motorcycle Engine?

The reasons for the ticking sound in a motorcycle engine are as follows: A distinct ticking sound from the cylinder head area of the motorcycle indicates that the valve clearance is relatively large. Under the effect of air collision, this produces the ticking sound. Experienced mechanics often adjust the valve clearance based on the intensity of this ticking sound. Relevant information is introduced below: After starting the motorcycle, as the engine heats up, the thermal expansion coefficient of the aluminum alloy cylinder head is greater than that of the steel valves. Therefore, some smaller valve clearances gradually widen. If the valve clearance exceeds the permissible value when the engine cools down, it will produce a ticking sound when heated. Hence, when hearing the ticking sound from the valves, it is advisable not to attempt adjustments based on personal experience. Instead, it is best to take the motorcycle to a professional repair shop for maintenance to prevent accidents during the repair process, which could cause further damage to the motorcycle and lead to potential risks and issues while riding.
