The Mini Cross 50 R12 is powered by a 49cc, air-cooled, two-stroke fed by a 14mm Dell'Orto carb. For kids just getting used to riding or racing a mini, the BETA has an automatic transmission so they can concentrate on learning how to handle their machine without worrying about shifting and clutch work just yet. A durable steel frame, 30mm fork, and single shock keep the chassis simple. Also available is the Mini Cross 50 R10, which is the very same bike but with 10-inch wheels front and rear. The 50 R10 is lower to the ground so youngsters ages 4 through 7 years old (company advised age range) can feel comfortable on a motorcycle that’s a little more powerful, but not quite as tall.
