I own a Hyosung XRX 125, and live in the middle part of Norway. I`m riding my bike everyday at work, through blizzards and on icy and snowy roads. The engine starts and runs very well in all conditions (I have been riding in -20 degrees celsius) and so far it looks as if it`s going to run problem free through this winter... I`m impressed by its capabilities so far...maybe thanks to the 4 strokes engine.
