The local dealer did have a CB500X. We sat on it. It was, ok. Nothing too spectacular. Simple (standard) controls, nothing in the way of wind protection for the grips. Seat was nice and wide, but this made it a little tougher for Shesaid to feel comfortable with her feet on the ground, despite the 32" seat height. Wheels are a bit smaller than I'd like, and the stock tires aren't going to be much for adventure. The front fender placement is also pretty snug to the tire, so tire options might be a bit limited until some modifications are made. Not to mention sticks, pinecones, rocks, and even acorns that are going to get up in there.
I'm not saying it's a bad choice/bike, I'd really like to try out the 500cc twin, but depending on your idea of adventure, it might need some tweaking.
