First gear is the starting speed, typically ranging from 0-5 km/h for the vehicle. Second gear corresponds to speeds of 5-20 km/h, third gear to 20-40 km/h, fourth gear to 40-60 km/h, and fifth gear to 60-100 km/h. Introduction: During driving, when shifting gears, the engine speed is usually maintained at around 2000 RPM. It's best not to exceed 2500 RPM during gear shifts. It's important to note that different vehicles use different engines and transmissions, so drivers can identify the right shifting moment by listening to the engine sound. Additional Information: While driving, it's crucial to avoid lugging the engine, as this increases engine stress, raises fuel consumption, and can cause significant damage to both the engine and transmission.

When riding a motorcycle, the speed corresponding to different gears is not a fixed number—it depends on the bike model and engine size. From my personal experience, first gear is mainly used for starting, with speeds between 10 to 20 km/h, suitable for slow movement or climbing hills. Second gear ranges from 20 to 40 km/h and is commonly used for acceleration. Third gear is around 40 to 60 km/h, ideal for steady urban riding. Fourth gear covers 60 to 80 km/h, while fifth gear, for speeds above 80 km/h, is suited for highway cruising. However, specifics vary by bike: a 250cc sportbike can easily reach 50 km/h in second gear, whereas a heavy cruiser might only go around 15 km/h in first gear. I’ve also noticed that riding on mountainous terrain requires more use of lower gears, and carrying a passenger affects acceleration. Beginners should refer to the bike’s manual or test in real road conditions, paying attention to engine vibrations—shift up if the vibrations are too strong. Don’t just memorize numbers; practicing to find the rhythm is safer.

From a mechanical perspective, motorcycle gear speed ranges vary significantly depending on factors like gear ratios and engine displacement. First gear typically covers 0-20 km/h, providing high torque for starting; second gear (20-40 km/h) enables smooth acceleration; third gear (40-60 km/h) serves as a transition zone; fourth gear (60-80 km/h) suits high-speed riding; while fifth gear (80+ km/h) is ideal for cruising. However, in real-world riding scenarios - like my 400cc naked bike that easily reaches 45 km/h in second gear, compared to my friend's small scooter struggling at 30 km/h in third - actual performance differs. External conditions also matter: uphill or when carrying heavy loads, higher gears may cause stalling, requiring downshifting in advance, while downhill riding benefits from higher gears for fuel efficiency. I recommend riders judge by engine sound: upshift when it roars, downshift when it labors. Flexible adjustment matters more than rigidly following numerical ranges.

As a frequent rider, I prioritize safety: the approximate speed ranges for motorcycle gears are 1st gear 0-20 km/h for starting, 2nd gear 20-40, 3rd gear 40-60, 4th gear 60-80, and 5th gear 80+. However, the key is to match the shifting points according to road conditions. Using 1st gear at too high a speed can damage the engine; going too slow in 5th gear risks stalling. In the city, I often use 2nd and 3rd gears, switching to 4th and 5th on highways; lower gears provide more stability when climbing hills. Each bike is different: a beginner's motorcycle might reach its limit at 50 km/h in 3rd gear. Practice testing speed boundaries on open roads gradually and develop the habit of anticipating conditions to ensure safe travel.
