Avon Spirit ST Front Tire - 120/70ZR18 59W TL 1DK

Need top‑tier grip and confidence in every twist of the throttle? The sport‑touring motorcycle front tire Avon Spirit ST 120/70ZR18 59W TL (Part # avt640594) solves the problem of soggy corners and lackluster mileage by delivering a balanced mix of wet performance, stability, and long wear. If you ride through rain, highways, and winding roads, this front radial tire gives you the confidence to push harder without compromise.

This Avon Spirit ST tire uses dual‑compound formulation and highly loaded silica to provide exceptional wet and dry traction, especially when leaning into curves or braking under less than perfect conditions. The 3D sipe technology adds stability and helps the tire warm up quicker — that means more grip right away, even in cooler or damp mornings.

For riders who count miles, this sport‑touring motorcycle front tire doesn't skimp on durability. With its radial construction, blackwall sidewall, and load index 59 with speed rating W, it handles both light and aggressive riding. It’s made to deliver reliable performance over many road miles — whether commuting daily or pushing through long weekend rides.


Features and Benefits 

  • Part Number avt640594 – ensure correct replacement and compatibility with your bike.

  • Radial Construction – better stability, responsive steering, smoother ride at speed.

  • Dual Compound + Highly Loaded Silica – enhanced wet grip & longer tread life.

  • 3D Sipe Technology – improves stability by reducing tread flex; helps warm up faster.

  • Blackwall Sidewall, Speed Rating W (max ~168 mph) – looks clean, safely rated for highway & spirited riding.

  • Load Index 59 – supports weight load requirements for many sport‑touring front ends without sacrificing performance.


Upgrade Your Ride Quality & Confidence

Say goodbye to slippery corners, faded grip in rain, and tires that wear out too fast. With the Avon Spirit ST sport‑touring motorcycle front tire, you get the best of both worlds: aggressive wet & dry grip plus reliable longevity. You’ll feel the difference in every lean, every stop, every twist of throttle.

REVIEWS

JD

Absolutely impressed with how the Avon Spirit ST grips in the rain here in Seattle! Took it on twisting roads after the storm, and cornering feels steady, not slippery at all. Mileage is also surprisingly solid—this front tire handles everything from daily commute to weekend canyon blasts.

Since swapping to the Spirit ST 120/70ZR18 up front on my ST1300 here in Austin, the stability at highway speeds is night and day. It feels planted, even when the road’s wet. Plus, the ride is smoother over imperfect pavement too. Worth every cent.
