Mag
If you've looked around DRN I'm sure you've figured out that MXA (Motocross Action) isn't real popular in these parts. I'm getting a bit of a reputation around here as being an MXA advocate, so I'll hold true to that reputation and recommend it. Great pics, family-friendly content/ads, decent product reviews, and good bike tests. It does lack some of the "inside info" that some of the other mags have, however (like Racer X).
Or you could get just about every major mag for less than $100 per year and decide for yourself!
