Ain't that typical ;) A friend's two girls like riding together (they're wierd) but hate riding with their big brother. Actually, the older girl is getting past the stage she'll ride with midget as midget is "too slow". The older one has just moved to a TTR125L & midget is still on her LT80 (but it fits her now lol).
Just thinking back a couple of years, they shared the LT80 but in the words of the older girl, "her sister was fastest". Then midget rolled the quad on herself & she slowed down (she also stopped watching whoever was behind her to make sure they were there - scarey in the trees).
Definitely more fun with someone to ride with & always great to see the young ones into it.
