The KTM 50 SX Mini is practically a toy bike, built exclusively for young children looking to break into dirt bike racing. How young, exactly? Try three to four-year old children.
Remarkably light at just 88 lbs, the 50 MX Mini retains a high standard of safety, controllability, and plain overall fun. The ride height - 4.27 ft - is also short relative to the kids riding it and to give parents ease-of-mind, KTM built a high-quality chassis with easily applied disc brakes, top-quality components, and a reliable engine with an easy-to-operate centrifugal clutch.
The KTM 50 SX Mini is the perfect bike for beginner riders. It includes premium features like adjustable seat height, disc brakes at the front, and a long travel rear suspension, as well as the best power output available in the class.
Speaking of its power, the KTM 50 SX Mini boasts of a 50cc 1-cylinder, 2-stroke water-cooled engine that is mated to a centrifugally controlled automatic clutch, making it easier for junior racers to ride their bikes without worrying about the clutch or changing gear. Simply hitting the gas is enough. Similarly, the clutch can be adjusted in the workshop to the riding ability of the budding racer.
Starting slow is always the best option and once little riders get the hang of it, then you can let the bike loose.

Just a shade above the 50 SX in KTM’s pecking order for upstart dirt bikes is the 65 SX. Whereas the former caters to the little tikes, the latter is just the right sports machine for all up-and-coming riders from 8 to 12 years of age and up to a height of about 1.60 m (5.25 ft).
