What is the Impact of Motorcycle Aspect Ratio?
1 Answers
Motorcycle aspect ratio refers to the relationship between tire sidewall height and tire width. A smaller aspect ratio means thinner tire sidewalls, while a larger aspect ratio indicates thicker tire sidewalls. Introduction to Aspect Ratio: Aspect ratio is a tire specification that represents the percentage of the tire's cross-section height to its maximum cross-section width, essentially describing the height-to-width ratio of the tire. For example, in 130/70-12, TS-660, the number 70 indicates the tire's aspect ratio. High vs. Low Aspect Ratio: Tires with high aspect ratios have longer sidewalls, providing better cushioning and relatively higher comfort levels. However, they offer poorer road feedback and weaker lateral resistance during cornering. Conversely, tires with low aspect ratios and large inner diameters feature shorter sidewalls and wider treads, resulting in larger contact patches and the ability to withstand greater pressure.
