Mods,
If this post bends the rules for this section, feel free to delete. Some folks might not know about this good place to get motorcycle wallpaper for their computer (I'm not affiliated. I've just used it for years). It has pretty much all bikes, but here are two links for the "good stuff"! Note that the R² pics are of non-US models (black frame, different license plate holder, etc.) Interesting to see the differences. Be sure to check out the "WR250X Special".
