I am a 37 year old guy owning a brand new 50ccm Jinlun JL50QT-5. Hey, my first brand new vehicle ever! I bought it only to save fuel when riding to work. My car and my Triumph need too much of it, and spare parts for the Jinlun are quite cheap also.
Well, at least at the beginning it was about saving fuel. Now I enjoy trying to get maximum acceleration and minimal fuel consumption. Still some work to do, 2,6l per 100 km is too much. But acceleration and speed are fine.
