The Avon Spirit ST is an ultra-high-performance sport touring motorcycle tire designed for responsive handling, dependable stability, and confident traction in a wide range of riding conditions. This front tire is sized 120/60ZR17 with a (55W) load and speed rating, making it suitable for compatible sport and sport touring motorcycles that specify this fitment.
Avon’s advanced 3D Sipes use interlocking three-dimensional points hidden within the tread grooves to improve stability and grip while limiting tread flex. This design also helps the tire warm up quickly, supporting consistent performance during everyday riding and spirited touring. The Spirit ST is engineered to provide balanced steering response and controlled handling for riders who want sport-oriented performance without sacrificing touring capability.
A dual-compound tread provides enhanced grip, handling, and mileage by placing performance-focused rubber where it is needed most. The highly loaded silica compound, combined with state-of-the-art polymer technology, helps deliver reliable wet and dry traction. As an Avon motorcycle tire, the Spirit ST offers a practical combination of cornering confidence, road feedback, and long-distance usability.
