The speed range of a 100cc motorcycle in different gears can vary depending on various factors such as the motorcycle's design, engine specifications, and gear ratios. Additionally, different motorcycle models may have slightly different gear ratios, so the specific speed range can vary between bikes.
First Gear: In first gear, which provides the most torque and least speed, a 100cc motorcycle can typically achieve speeds ranging from around 0 to 15-20 miles per hour (0 to 25-32 kilometers per hour).
Second Gear: Shifting to second gear allows for increased speed. In this gear, a 100cc motorcycle can generally reach speeds between 15-20 to 25-30 miles per hour (25-32 to 40-48 kilometers per hour).
Third Gear: Third gear provides even more speed, and a 100cc motorcycle can typically achieve speeds ranging from 25-30 to 35-40 miles per hour (40-48 to 56-64 kilometers per hour).
Fourth Gear: Moving into fourth gear, a 100cc motorcycle can typically reach speeds between 35-40 to 45-50 miles per hour (56-64 to 72-80 kilometers per hour).
Fifth Gear: Some motorcycles with a five-speed transmission have a fifth gear, often referred to as an overdrive gear, which allows for higher speeds with reduced engine RPM. In fifth gear, a 100cc motorcycle can generally reach speeds ranging from 45-50 to 55-60 miles per hour (72-80 to 88-96 kilometers per hour).
Keep in mind that these speed ranges are approximate and can vary based on the specific motorcycle model, engine performance, and other factors. It's also important to ride within the speed limits defined by local traffic laws and regulations for your safety and the safety of others on the road.
