Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to an enhanced grip motorcycle tire. Background Art

[0002] Current small-displacement motorcycle tires are typically required to travel on different types of road surfaces, some of which have a low coefficient of friction, such as wet asphalt, slippery roads in rainy weather, track crossings, brick paved roads, or cobblestone roads. When a motorcycle travels on roads with a low coefficient of friction, the friction is low, making it prone to slipping and rolling over during sharp turns. To ensure driving performance and safety, the tires must have strong and precise grip from rapid acceleration to smooth and side cornering, while also having good drainage, stability, and traction, and better performance in terms of service life and wear. However, existing motorcycle tires still suffer from poor grip, poor drainage, and poor handling when traveling on roads with a low coefficient of friction. Utility Model Content
