My name is Sam Johnson Im a pretty small guy about 5´10´´ 145 pounds. I have a KX 125 now but am looking to upgrade to a more powerful bike. I was wondering if anyone could give me some advice on choseing a bike. I want a bike that is good for the sand and has power to get me arround in the deep soft sand. Is a 2 stroke better or a four stroke? What brand would you recomend? Honda, Yamaha etc. I dont want a bike that is too heavy. Any suggestion would be apreciated.
