Bridgestone Battlax BT46 Rear Motorcycle Tire 130/70-18 63H — Silica Wet Grip, Touring Durability

The Bridgestone Battlax BT46 rear 130/70-18 63H is a bias-ply, tubeless motorcycle tire engineered to improve wet traction while preserving the dry handling and wear life riders expect from the Battlax line.

Building on the long-standing reputation of the BT45, the Battlax BT46 updates tread design and rubber chemistry to deliver steadier, more confident rides across urban streets, long tours and twisty back roads. Bridgestone introduced a silica-enriched single-compound in the rear to boost grip in damp conditions without sacrificing longevity, and retained the proven pattern geometry that made the previous generation popular with vintage sport and touring motorcycles.

How does the BT46 improve wet-weather performance?

The BT46 uses a silica-based single tread compound in the rear that increases traction on wet surfaces by improving rubber flexibility and water evacuation at the contact patch. Paired with a revised BT45-derived tread pattern, the tire disperses water more effectively while maintaining stable handling.

• Silica single-compound rear rubber for better wet adhesion
• Updated tread pattern based on the BT45 design for improved drainage
• Optimized contact patch for consistent wet grip and steering feel

Will it still handle well on dry roads and last for touring miles?

Yes — Bridgestone balanced the new wet-focused compound with a construction and pattern that preserve the dry handling characteristics riders expect from the Battlax line. Wear life remains comparable to BT45, making the BT46 suitable for both daily riding and extended trips.

• Bias-ply construction tuned for stable cornering and predictable feedback
• Compound formulated to resist rapid wear while offering upgraded grip
• Durable design targeted at touring and vintage sport usage
