I have similiar bike. I bought it last may. Its engine was broken and I paid 420€ for the whole bike. My dad was restored it almost throughout the year. Only a few decal are missing. Btw maybe next month I get the lisence and I can drive with it. :)
The c model with its striking colors in particularly in thus blue 'black is very attractive... Very fast bikes... Just the ninja sticker don't belong there...
