Dunlop designed the D606 120/90-18 dual sport motorcycle tire to be street-legal with an emphasis on aggressive off-road riding. A full-depth tread pattern designed for rigorous off-road use yields excellent traction on everything from hard-packed fire roads to soft single-track trails. At the same time, the D606's tread compound is engineered for good highway durability and grip. Available in 21-inch front and 17-inch and 18-inch rear sizes to fit almost all off-road-capable dual-sport bikes.
