The Dunlop SX RSMART4 R 160/60R18 70W is a high-performance rear motorcycle tyre aimed at sport-tourers and agile naked bikes for both spirited road riding and long distance. It is engineered to deliver stable handling at speed while preserving comfort on longer journeys. The model emphasises a blend of agility and endurance for everyday use and extended trips. Advanced compound technology improves grip in variable conditions and extends expected mileage compared with previous generations. The tread layout supports rapid water evacuation which enhances wet grip and reduces aquaplaning risk.

Internally the tyre uses a construction that stabilises the contact patch under load and promotes even wear across the tread. This results in consistent steering response throughout the life of the tyre. The profile is tuned for precise cornering stability without harsh feedback to the rider. Reinforced sidewall features provide improved resistance to deformation under heavy loads and abrupt manoeuvres which helps maintain braking distance and posture during hard braking.

For riders this tyre offers predictable behaviour when pushing on B-roads and calm, composed performance on motorways. Improved rolling resistance contributes to efficient fuel use and the combination of comfort and responsiveness suits well-equipped touring motorcycles.
