50 SX MINI
NEVER TOO YOUNG TO LEARN
A real KTM for young crossers from the age of about 4 to 10 and a height of up to approx. 1.30 m. A real motorcycle with high quality components that's child's play to control and whose engine excels with linear power development and a beginner-friendly automatic clutch.
ENGINE & EXHAUST
The high performance cylinder sets in conjunction with the pipe and reed intake system the performance standard within the highly competitive 50cc class.
ENGINE
The modern, extremely compact, 2-stroke engine sets the benchmark in its class with its very controllable power. Thanks to the 3-shaft concept, the crankshaft is close to the bike's centre of gravity. This not only benefits the handling; it also provides a flow-optimized inflow angle at the intake membrane - a prerequisite for maximum performance.
CLUTCH
Developed by KTM, the centrifugal multi-disc automatic clutch provides manageable acceleration and makes riding this motorcycle the easiest thing in the world. It can be adjusted to the specific requirements of the track and the rider in minutes and without any special tools.
AUTOMATIC TRANSMISSION
The centrifugally controlled, multi-disc automatic clutch developed by KTM delivers easily controllable acceleration and makes riding the 50 SX the easiest thing in the world. Furthermore, it can still be quickly and easily adjusted to the specific requirements of both track and rider using the "KTM clicker system" - in a matter of seconds and with no special tools required.
CHASSIS
KTM engineers just love dropping weight year after year. The result: the 2019 KTM SX models are the slimmest, lightest dirt bikes out there.
WHEELS
Just like the big factory bikes, the 50 SX is equipped with ultra-light, black anodized aluminum rims that easily withstand even the biggest of jumps. The 50 SX is equipped with the very latest generation tire from MAXXIS, featuring a profile that guarantees optimum grip on every surface.
SUSPENSION
A high quality, upside-down telescopic fork from WP Suspension, featuring 35 mm diameter outer tubes and 100 mm suspension travel, ensures outstanding ride stability. A WP shock absorber connected directly to the swingarm also supplies 147 mm of suspension travel at the rear wheel.
BRAKES
Both at the front and rear, state-of-the-art hydraulic disc brakes from FORMULA ensure best possible retardation. The exclusive, self-cleaning Wave brake discs stand for the ultimate in race technology and outstanding safety.
ERGONOMICS & COMFORT
READY TO RACE ergonomics give you the edge on the track, ride harder for longer.
HANDLEBAR
The ergonomic Renthal handlebar made from a high-quality aluminum alloy ensures the highest levels of stability and safety. A Renthal crash pad around the centre brace protects the rider from hard knocks.
BODYWORK & GRAPHICS
The bodywork is derived from the full-size SX models and provides perfect ergonomics, well thought-out contact points for the rider and maximum freedom of movement. In addition, smart design solutions for the new front and rear fenders are prime examples of an intelligent design, which guarantees maximum stability through a well thought-out structure and mounting.
DECALS
The 2019 SX models feature the latest in-mold graphics, matching the factory-look orange frames and new bodywork perfectly. They have a fast and aggressive style that screams READY TO RACE, leaving no doubt as to the bikes' high-performance intentions.
