What is the difference between international gear shift and rotary gear shift for motorcycles?
2 Answers
International gear shift and rotary gear shift differ in shifting methods. Below are the differences between international gear shift and rotary gear shift: International gear shift: First gear is engaged by pressing down, while gears from second gear onwards are engaged by lifting up. Additionally, it is not possible to shift directly from the highest gear to neutral; you must downshift one gear at a time. Rotary gear shift: You can continuously press down to upshift, and when you reach the highest gear, pressing down once more will cycle back to neutral. Below is additional information on motorcycle speed regulations: Flat roads: 40-60 km/h is the economical speed for motorcycles, offering a balance of safety, fuel efficiency, and minimal wear on the vehicle. General motorcycles: Most motorcycles can reach speeds of 80-120 km/h. Racing motorcycles: Dedicated racing motorcycles can exceed speeds of 300 km/h. Scientific research motorcycles can reach speeds of up to around 700 km/h.
The difference between the international gear shift and the loop shift on motorcycles is quite noticeable. I think the international shift is easier for new riders to get started with. The shifting sequence of the international shift usually involves pressing down to first gear, then lifting up sequentially to higher gears, with each gear having a fixed position, making it less likely to confuse the positions. When I first started learning to ride, I found this design logic clear, with neutral being safely positioned between first and second gears. On the other hand, the loop shift has a circular pattern, where pressing down continuously cycles through the gears, sometimes accidentally shifting from the highest gear back to neutral, which can cause sudden speed changes. For beginners, the international shift results in fewer mistakes during the learning process, lower risk of misoperation, and helps develop proper riding habits. This stability shows its advantages during daily commutes, avoiding the awkwardness of frequently searching for gears in congested urban areas. In summary, the international shift offers a linear progression with a strong sense of advancement, while the loop shift is a convenient but less refined design, more suited for experienced riders in quick-shifting scenarios.
