We have a TRX 450 too. Now it's wide +2 now but even before than, a smooth take off & quick off the throttle. Now it's cam'd pipe'd exhaust n' stuff & the girls have no problem riding the Honda. And they aren't always experienced but will be sometime. I've been teaching my girl to ride the Banshee, she's rippin it on the throttle. Now she knows to position the quad where she won't be stuck.. and need reverse. So they'll learn. After learning to ride the Banshee she'll have no prob riding and 400 or 450.
The TRX kicker is easy to kick over. The kicker is double the Banshee's kicker size.
Bro's girl rides the red Honda, no probs in the trails nor dune.
