Mariana Balbi is one of the fastest women motocrossers on the planet. In fact, she is the only female to ever earn a MXGP point in competition. In this month’s issue of TransWorld Motocross, Casey Davis penned a profile feature with the Brazilian racer. When we shot her accompanying profile shots, we joked about busting out the bikini and were pumped when she agreed! Lucky for you, the crew at BTO Sports presents today's wallpaper gallery. All photos can be clicked on and saved for desktop and iPhone wallpapers. Enjoy!
