I'll start, I've owned a few street bikes in the past so do have some riding experience. But I just got my first dirt bike, so I'm feeling pretty new to the sport right now, which is a lot of fun.
We got our son Gavin a bike for his 6th birthday last year, a Honda CRF50. It's a kick to ride.. 3 gears, no clutch, start in any gear... he's more into it now than he was 6 months ago, and excited to go out riding with me (as am I). I'll look for a picture of it..
And my bike is a 2007 KTM XCF-w. I am thinking this is the perfect entry-level dirt bike for me- same size as the bigger CC KTM's, but lighter, so easier to handle. It's pretty fast too, if I get to the point where I'm held back by the smaller engine, I will have become a much better rider than I am today.
