Off-road ridin' don't come much cooler than on the Ducati Desert Sled, a scrambler that riffs--and roars--on the iconic bikes of the 1960s and '70s. Since the introduction of the line in 2014, the firm's offerings have been better and better, and it'll be interesting to see where they go from this incarnation that sports an injected 803cc engine with 75-hp, LED lights, LCD instruments and even under-seat USB ports.
