I purchased a UM DTF-200. I never use in off-road, I only use to trip to my job, 15 daily Km, and I´m experiment failures in the electric starter, the red rear lights and the rear brake (most important), my life is in risk. I want to know if someone of you have the same troubles on this bike. The post service is regular, sometimes the say lies to me and don´t be clear with me. Thanks.
