My husband found a KFX 80 for our daughter, we also have the option to buy a Yamaha Raptor or a Honda TRX90. I'm a Yamaha girl, I know nothing about the Kawi. Someone please fill me in! Thanks!

 

Welcome to the forums.
Tha KFX80 is a Suzuki LT80. Very dependable. CVT (no shifting)
The TRX90 is bulletproof. She'll need to learn how to shift. It is a clutchless shift.
I'll end my opinions there.

 

Lt80/kfx80 is the only way to go imo, easy to ride and they won't grow out of it as fast. It's quicker so it will keep their attention longer.
Honda is very reliable but like Jack said you have to shift it, there kinda slow so they may get board of it sooner. 4 strokes are very tought o work on and costly to repair.

 

I have a 04 trx 90 that I bought used for my boys and they loved it except for not having and automatic trans, electric start and reverse. The still ride it once in a great while, but since I brought home a 125 breeze and a 90 sportsman, it sits in the barn most of the time. My oldest boy will get on it and rip it around once in awhile, he likes it because it's small enough and light enough he can make it do most anything he wants.
