Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Avon Spirit ST is widely regarded as a high-performance sport-touring tire that offers exceptional grip and stability across diverse weather conditions.

The Avon Storm 2 Ultra is widely regarded as a high-mileage sport-touring tire that excels in dry-weather stability and longevity.

Observations
- Users of heavy, high-torque machines like the Hayabusa and ZZR1400 report high satisfaction with stability and wear, though some find them unsuitable for aggressive riding in cold/wet conditions.

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
