Avon Spirit ST Front Tire - 110/80ZR18 58W TL 1DK

If you’re tired of feeling sketchy on damp roads, the sport‑touring motorcycle front tire Avon Spirit ST 110/80ZR18 58W TL (Part # avt640603) is exactly what you need. This tire delivers dependable grip and confidence, whether you're cutting through early‑morning mist or cruising through scenic curves at highway speed. The right front tire can make the difference between riding with anxiety and riding with thrill.

This tire is built with radial construction and a blackwall sidewall, giving both stiffness and flexibility where needed. The dual‑compound tread and silica‑enhanced rubber boost grip in wet conditions while offering better wear resistance under daily riding. With its W speed rating and load index 58, it handles brisk acceleration and braking without compromising stability.

For sport‑touring riders who want long rides, aggressive cornering, and peace of mind, this Avon Spirit ST front tire balances performance, durability, and comfort. The 110 mm width, 80% aspect ratio, and 18‑inch diameter create the ideal profile for front ends needing both nimble response and steady straight‑line control.

Switched to the Avon Spirit ST 110/80ZR18 up front on my touring bike in Denver, CO, and day vs night difference. The grip in wet turns is no longer sketchy and highway ride is smooth without buzzing. Great tire.

Rode through the Blue Ridge Parkway and the Avon Spirit ST handled everything—rain, gravel, sweeps—without drama. The tall sidewall absorbed bumps well. Definitely a solid front tire for long rides.
