N-Tec construction (New Technology) is Dunlop?s very best construction road racing tyre.The KR449 rear tyre features a nylon carcass overlaid with two nylon breaker belts and a continuously wound, aramid-fiber tread belt for cooler-running, excellent straight-line stability and virtually no circumferential tyre growth. Dunlop?s N-Tec steel bead and its high-modulus bead apex combine to offer improved feel for the rider as the tyre nears its cornering limit, producing the ?predictability? that has become a signature characteristic of Dunlop road racing tyres.
