Posted on by  

The Beta Minicross R 12 is a small motorcycle aimed at the kids (aged 8/12) that want to learn the skills of off road ridding at a small age.

The bike was carefully created to help the small rider learn safely how to deal with tight curves, high jumps and difficult tracks and offers a fun riding experience mixed with an intelligent chassis and a lively engine.

Talking about the engine, the Beta Minicros R12 is powered by a single-cylinder, 2-stroke, air cooled engine with lamellar induction in the crankcase. The engine sends its power to the rear wheel through a single speed transmission and is linked to a 2 liters fuel tank.

The motorcycle’s speed is kept in check by a set of drum brakes while the ride quality is assured by a solid Ø 30 mm front fork and a rear shock absorber.
