2013 KTM 50SX Review

2013 KTM 50SX

THE PERFECT LAUNCHPAD INTO THE MX WORLD

A real KTM for the smallest of future MX champions. The 40 kg (87.7lb), lightweight 2013 KTM 50 SX sets standards in terms controllability and racing fun. It has everything including a high-quality chassis with easily applied disc brakes, top-quality components wherever you look, a powerful, reliable engine with easy-to-operate centrifugal clutch.

 

2013 KTM 50SX Features and Benefits

ADJUSTABLE AUTOMATIC TRANSMISSION

The new, centrifugally controlled, multi-disc automatic clutch makes riding the 2013 KTM 50 SX the easiest thing in the world. Completely redesigned by KTM, the 50 gram lighter clutch delivers significantly improved and more controllable acceleration. 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.

WP CHASSIS

The high-quality, upside-down front fork from WP Suspension, with 35 mm (1.38 in) diameter outer tubes and 185 mm (7.28 in) suspension travel, provides excellent ride stability and guarantees optimum damping properties and supreme responsiveness. At the rear wheel, a WP shock absorber hinged directly to the swingarm also supplies 205 mm (8.07 in) suspension travel and excels with superior and reliable damping, even on the highest of jumps.

ENGINE

The modern, extremely compact, 2-stroke engine clearly sets the benchmark in its class with its very controllable power. Equipped with a newly developed automatic clutch, the 2013 KTM 50 SX even easier to master. Thanks to the 3-shaft concept, the crankshaft in the KTM engine is closer to the bike’s center of gravity, which not only benefits the handling; it also allows a flatter and thus flow-optimized inflow angle of the intake membrane for maximum performance.

OPTIONAL RESTRICTOR KIT

To enable adaptation of the race-ready performance of the 2013 KTM 50 SX to the needs of the youngest beginners as well, a power-reduction kit including a smaller carburator is available from the PowerParts range, with which the engine can be restricted to a moderate 5.5 hp.

BRAKES

Both at the front and rear, optimally dimensioned disc brakes from FORMULA ensure the best possible deceleration on the 2013 KTM 50 SX. The exclusive, self-cleaning wave-type brake discs stand for the ultimate in race technology and outstanding safety.

WATER COOLING

The KTM 50 SX’s liquid-cooling system, with two large radiators and additional cooling for the crankcase, prevents the engine overheating, even under the most extreme loads.
