Beta, renowned for its off-road lineage, has crafted this model to deliver a blend of performance and fun, making it an excellent choice for mini motocross enthusiasts. At the heart of the Minicross R 12 is a spirited 49cc single-cylinder, two-stroke engine that strikes an ideal balance between power and manageability.

With a seat height of 740 mm (29.1 inches) adjustable for the smallest riders, the bike accommodates a range of skill levels. The 2-liter fuel tank ensures that young racers can spend more time riding and less time refueling, and the kick starter provides simplicity and reliability when it's time to hit the track.
