The Times profiles the "Hayes Diversified Technologies M103M1," a military variant of the Kawasaki KLR650 motorcycle that runs of the ever-present JP-8 diesel fuel. The result isn't a performance beast, but does get 96 miles to the gallon and is easily field serviceable.
On a half-hour test ride, the M103M1, though sluggish at first, gathered speed with dogged insistence. The footpegs and handlebars buzz as the engine revs – the counterbalancer that controls vibration in the stock KLR has been omitted to save weight and reduce complexity. Shifting through the five-speed gearbox gets the M103M1 past 90 miles an hour, a speed it will hold, apparently, until the end of time.Getting your hands on one if you're not a Marine is difficult; Hayes is pretty much backlogged making modifying the bikes for the military.
