The Avon SPIRIT ST 170/60R17 72W is a sport-touring motorcycle tyre crafted for riders seeking controlled winter and transitional-season handling. It sits in the performance-touring segment and is intended for mixed-road use where grip and agile response matter. The tread profile and compound are developed to provide predictable behaviour across a range of temperatures.

A balanced pattern promotes effective water evacuation and reliable wet grip while the contact patch shape supports consistent cornering stability. The tyre uses multi-radius construction to keep braking distance short and to deliver even wear across diverse riding styles. Fine siping and groove placement improve traction on damp surfaces without sacrificing riding comfort.

For the rider this tyre enhances steering response and confidence when leaning into wet bends and negotiating urban surfaces. Its construction also helps maintain mileage expectations for sport-touring use and preserves feel at the contact patch. Overall the SPIRIT ST delivers secure braking performance and steady handling for all-round riding demands.
