It's widely known that kids are the future of the world, and what better way to raise those kids than on a KTM dirt bike? Made in Austria and built specifically for the youth rider, the 2015 50 SX brings big-bike performance to a pint-sized package, all for $3,899 of lawn-mowing money. So long as junior is comfortable with a 27-inch seat height and 88-pound dry weight, the 50 SX should be a great learning tool for your youngster. The 49cc package may not be small, but depending on what your kid is looking for, it may be the perfect amount of punch to haul them around as they develop their skills and create awesome memories. Get more info on the latest minis.

From the infamous KTM junior supercross challenge to the starting gate of Loretta Lynn's amateur national, these Austrian-made minis have made a name for themselves as being fast, nimble, and extremely fun for young riders and racers to play and compete on. The 2015 50 SX has a seat height of just 26.9 inches, while the 49cc bike clocks in at 88 pounds dry and $3,899 out of the college fund (just kidding. Seriously, kiddos, stay in school!). Youth riders grow at an astonishing rate, and this is part of the reason why KTM offers such a vast array of mini machines. See below for additional specifications of the 2015 50 SX, and be sure to take a glance at all of the other orange minis that the Austrians have to offer.

"Don’t let the auto clutch fool you, this is a race bike built for experienced young riders, not first timers. These KTM 50s are built for big tracks and big speed, the only thing little is the kid at the controls."
