How fast can a 125cc motorcycle go?

Domestic 125cc motorcycles can reach a maximum speed of 90-100 kilometers per hour. Below is relevant information: Motorcycle speed: Most motorcycles can reach 100 kilometers per hour, while more advanced models can achieve speeds of 180 kilometers per hour or even exceed 200 kilometers per hour. Single-cylinder 125cc motorcycle power: The typical power output for a single-cylinder 125cc motorcycle ranges from 7 to 8.3 kilowatts, while a 150cc single-cylinder engine generally produces between 8.8 and 11 kilowatts. Due to variations in engine technology among different motorcycle manufacturers, the power output of engines also differs. Engine power is influenced by factors such as displacement, vehicle weight, and engine technology (e.g., turbocharging), so motorcycles with the same 125cc displacement may not necessarily have identical power outputs. Since engine power is related to rotational speed, there are inevitably differences in the engine power curve (essentially the torque characteristic curve).

Is a 125cc Motorcycle Considered a Moped?

125cc motorcycles are classified as light motorcycles, while 30cc-50cc vehicles are categorized as mopeds. According to national standards, any motorcycle above 50cc is considered a standard motorcycle. Below are relevant details: Mopeds: A moped is a type of motorcycle that must comply with all technical standards and legal requirements for motor vehicles. Compared to standard motorcycles, mopeds have lower maximum design speeds, engine displacements, or total motor power. Their technical parameters and performance fall between electric bicycles and motorcycles, and they can be operated by individuals under 70 years old. Definition: Regardless of the propulsion method, a moped is defined as a motorcycle with a maximum design speed not exceeding 50km/h. If powered by an internal combustion engine, its displacement must not exceed 50mL; if electrically powered, the total rated output power of its motor(s) must not exceed 4kW.

Can a 125cc scooter carry a passenger?

125cc scooters cannot carry passengers. Here are the specific details: Legal regulations: According to traffic laws, light motorcycles are not allowed to carry passengers. Light motorcycles refer to those with an engine displacement greater than 36CC but less than 49CC (i.e., motorcycles below 50CC). Any motorcycle with a displacement of 50CC or above (including scooters) can carry passengers. Important notes: To legally operate a motorcycle on the road and carry passengers, the driver must possess an E or D license and have the motorcycle registered with a valid vehicle license. Both the driver and passenger must wear safety helmets during operation.

What is the optimal sprocket ratio for a 125cc motorcycle?

For a 125cc motorcycle, the front sprocket most commonly has 14 or 15 teeth, while the rear sprocket typically comes with 38, 39, 41, 42, or 43 teeth. Even for motorcycles of the same brand and model, the number of teeth on the sprockets may vary between different production batches. Here is some relevant information: Sprocket Teeth Count: The number of teeth on a motorcycle's sprockets is carefully calculated and set after considering various usage scenarios. When replacing them, it's important to purchase parts with the original tooth count and avoid making arbitrary changes. Alternating Contact Stress: The friction pair between the sprocket and chain involves alternating contact stress, which can easily lead to fatigue pitting on their friction surfaces. The indicator for judging the metal's contact fatigue strength is the contact fatigue limit, which is the maximum stress that does not cause pitting under a certain number of stress cycles.

How much does a 125cc motorcycle weigh?

An ordinary 125cc displacement motorcycle typically weighs between 150 kilograms and 250 kilograms. A motorcycle consists of seven main parts: the engine, transmission section, running gear, operation and braking section, cabin or cargo section, electrical system, and instrumentation. Broadly speaking, motorcycles can be categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. The weight of a motorcycle generally depends on its displacement, style, and brand. Heavy motorcycles with 600CC or above typically weigh around 400 jin (approximately 200 kilograms), while models like the 1800CC Honda Gold Wing and Harley-Davidson Ultra Glide weigh around 400 jin. Here are detailed introductions about 125cc displacement motorcycles: Overview: 125cc displacement motorcycles specifically refer to motorcycles with an engine displacement of around 125CC. Major motorcycle manufacturers have introduced various brand motorcycles based on this displacement. 125cc motorcycles are a relatively common type of motorcycle. Related Brands: In China, motorcycles with 125cc engines include brands such as Suzuki Haojue, Prince Motorcycle, Honda, BMW, and Yamaha, all of which produce derivative models based on this displacement. The engine parameters of these brands are generally consistent. Motorcycle Purchase Considerations: Check whether the motorcycle's paint is bright and even, and assess the quality of the paint; inspect whether the surface of the chrome-plated parts is bright and free of exposed damage or spots; ensure the welding joints are smooth; verify that the machined surfaces are smooth; confirm that all parts of the motorcycle are complete and undamaged; and check whether the front and rear shock absorbers are properly aligned.

What size hole should be drilled for an M12 screw?

If tapping is required, the standard pitch for an M12 screw is 1.75mm. Generally, a 10.3mm hole should be drilled. For harder materials like D2, a 10.5-10.7mm hole can be drilled. Below is relevant information: Determining screw type: The drill bit size for an M12 screw depends on the screw type. Even for screws of the same model, the required drill bit size may vary. For example, a 10.3mm drill bit can be used for tapping M12 screws, where the drill bit size is typically the screw diameter minus the pitch. Measuring pitch method: When measuring pitch, it's best to imprint the thread crest on white chalk for clearer marks that facilitate measurement. For metric pitch measurement, measure a length (e.g., 10, 15, or 20mm), count the number of threads in that length, then calculate the pitch. Threads specified in inches use imperial units, such as: G1".
