2012 KTM 50SX Review

The perfect launch pad into the MX world

A real KTM for the smallest of future MX. The 88 lb. lightweight 50 SX sets the standard in terms of controllability and riding fun. A high-quality chassis with easily applied rotor brakes, top-quality components wherever you look and a powerful, reliable engine with easy-to-operate centrifugal clutch.

Frame and suspension components

The chassis on the 50 SX is equipped exclusively with high-quality components — from the sturdy chrome-molybdenum steel frame to the newly developed WP upside-down fork. The torsionally, extremely stiff 1.38 in telescopic fork with new, forged triple clamps and 7.28 in suspension travel provides perceptibly better ride stability and more comfortable suspension.

Brakes

High-quality, hydraulically actuated disc brakes, with wave type brake rotors at the front and rear.

Renthal handlebars

High-quality, aluminum alloy Renthal handlebars designed specifically for the 50 SX contribute to the ergonomic package for optimum control. Power is now even more controllable with the new Domino throttle grip. The new, dual-compound rubber grips on the handlebar provide a secure hold for the hands, with the cross bar bearing a crash pad should you need one.

Water cooling

The liquid-cooling system of the 50 SX, with two large radiators and additional cooling for the crankcase, prevents the engine from overheating, even under the most extreme loads. Besides that, the smallest KTM can still take a fair bit of punishment — from bike-to-bike contact or contact with the ground.

Frame and suspension components

The chassis on the 50 SX is equipped exclusively with high-quality components — from the sturdy chrome-molybdenum steel frame to the torsionally stiff, multiple-adjustment WP upside-down telescopic fork with forged triple clamps, 1.38 in outer tubes and 7.28 in suspension travel.

Brakes

High-quality, hydraulically actuated disc brakes, with wave type brake rotors at the front and rear.
