Get her her own quad before you lose yours! My g/f started out riding years ago before I even met her, I got her a banshee on our 4yr mark...ended up being a wreck(needed a lot done to it) so I rebuilt it to look purty & traded it off for an '01 400ex and screwed a dealer out of about 3g's. She's happy with it since I put on the full WB's exhaust, rejetted,..some other cosmetic chit & it's going to be rebuilt to match my banshee soon, but she still likes to cut loose on the banshee, she's not skeered by any means. Someday down the road she's going to let me build her a full on drag banshee so she can go put a hurt'n on the boys. But for now, she's happy with her EX...she'll like it even more when she can really ride it(just had her ACL completely replaced). If nothing else, I got a pretty nice ranch/trail bike to play on.
Here's a pic of her old banshee, her present EX, & a typical shot at the dunes....notice she's on my banshee.
