My wife and I are planning a trip down 101 this summer and I’d like to rent a razor for the dunes. Having never driven the dunes or a razor before, what size razor would be fun? 1000cc , 900cc or 570cc. Their 900 cc actually looks better Equipped for the terrain. Since I’ll have the speed limiter set “ wife”, just how fast do things get on the dunes... anything to watch out for? Dunes look huge!
