My kid races stadium mx with his KFX80. They always bring in this deep loose cinder soil. We have a Moore built motor with plenty of 2 stroke power but his snow hog rears dig in too much off the line so he always gets a slow start but quickly builds speed once the back end gets traction. 180 degree turns are the same way. Any one have advice on the best rear tire for very loose soil. I'm thinking maybe a wider tire.
