Cape Agulhas tot Gansbaai - Dirt roads

[Giepie]

Me and my son are taking a bike trip to Cape Town.  We want to go to Cape Agulhas, but then the dirt raods to Gansbaai, via Suiderstrand.  On Google Earth I see there are a variety of dirt roads.  Are they ok for somebody without lot of experience on dirt?  He'll be on a 650GS,
