Hi there! From the search results, it looks like there isn't a 99CC Ryobi lawn mower listed. However, there are a few 125CC options that should give you a great cut. The top two models are the Ryobi 4-STROKE Petrol Lawnmower 125CC for R3499, and the Ryobi Petrol Lawnmower 125CC 410MM for R3435. Both of these come highly rated and have a 125CC engine size, which should provide plenty of power for most residential lawns. Let me know if you have any other questions!
