Dirt riders know KTM as the orange company, but that perception may change in the near future. The Austrian manufacturer is thinking of going green with an electric enduro that could soon be silently flying down the trails. The running test mule, developed with Arsenal Research, has been re-classified from a "research project" to a "development project," but that doesn't mean you'll be able to buy one any time soon. The bike's earliest arrival in showrooms would be in two years, with the cost likely being right in line with gas-powered KTMs. The test mule is said to weigh just 198 pounds, and has performance equal to a "light enduro," which we take to mean a 250cc four-stroke.
