I was wondering is the GN77A model from 1995 or 1996? The previous owner said it was from 1996, but somehow i doubt it. The frame plate says its GN77A. It has 2 front discs and apparently (license says) 25 kw although it has no trouble reaching 160 km/h (didnt try can it go faster). Whats the top speed for 25 kw?
