50 SX 2018

Fun & Junior

NEVER TOO YOUNG TO LEARN

The 2018 KTM 50 SX is a true KTM for young MX riders aged from around 4 to 10 years old and up to a body height of 1.30m.  It is a genuine dirt bike that, like its bigger siblings, is produced with top-quality components. This makes the 50 SX the first choice as a stepping stone into the world of MX or for the first racing step on the ladder. With the youngster in mind this package has an engine that delivers steady, controllable power, incorporating an automatic clutch that allows the rider to concentrate on the track, not shifting. This year’s model features revolutionary WP AER 35 front forks, fully adjustable rear suspension, a new exhaust, ultra-cool graphics and detail improvements that make going fast fun.
