The Dunlop D423 200/55R16 77H is a sport touring motorcycle tyre designed for riders seeking a balance between grip and endurance during mixed road use. Suited to modern naked and sport bikes, it performs well in both spirited riding and longer journeys. The tyre's profile addresses a variety of lean angles and speed ranges typical for road riding.

Compound formulation and tread geometry work to control rolling resistance while maintaining strong wet grip and controlled braking distance when conditions change. Strategic siping and grooves support efficient water evacuation and a reliable contact patch from upright to leaning positions. The construction emphasises even wear and thermal stability for consistent performance across mileage. Driving comfort is preserved through a carcass tuned to absorb irregularities without dulling feedback.

For motorcyclists this means predictable steering response and confident cornering stability on B‑roads and A‑roads. The tyre delivers durable performance and dependable behaviour that makes it a practical choice for everyday riding and longer weekend tours.
