KTM 50 SX 2021 for Sale at Virginia KTM in Virginia, QLD | Specifications and Review Information


NEVER TOO YOUNG TO LEARN

The KTM 50 SX is a true KTM for young MX riders aged between 4 and 10 years old. It is a genuine dirt bike that, like its bigger siblings, is produced with top-quality components. This makes the KTM 50 SX the first choice when stepping into the world of MX. Developed with the youngster in mind, this package has an engine that delivers steady, controllable power, incorporating an automatic clutch that is ideal for novice riders. It also features the latest WP XACT front fork with revolutionary AER technology, fully adjustable rear suspension, ultra-cool graphics and the ability to make going fast fun.

ENGINE

ENGINE

The high performance cylinder, exhaust pipe and reed intake system are perfectly arranged for maximum performance, setting the standard in the highly competitive 50 cc class.

CLUTCH

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.

COOLING

COOLING

Like the big KTM bikes, the 50 SX has a liquid cooling system, which even cools the crankcase. Generously sized radiators ensure outstanding heat dissipation for high reliability, even under extremely heavy duty.

EXHAUST

EXHAUST

The exhaust system was designed to perfectly match the characteristics of the engine, ensuring maximum output and a smooth power delivery over the entire rev range.

POWER REDUCTION KIT

POWER REDUCTION KIT

For absolute beginners the engine power can be reduced to a moderate 5.5hp using a kit from the PowerParts program.

FRAME

FRAME

The modern frame is made from lightweight, high strength chromoly steel profiles and combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability.

WHEELS

WHEELS

Like the full-size KTM Factory racers, the 50 SX has super lightweight, black anodized, aluminum rims providing the highest strength. The OEM MAXXIS knobbly tires grip superbly on any surface.

FRONT SUSPENSION

FRONT SUSPENSION

The KTM 50 SX has a modern, fully adjustable air fork: the WP XACT AER fork, made by WP SUSPENSION. This upside-down front fork with 35mm tube diameter and 205mm of travel ensures outstanding comfort, damping characteristics and directional stability. Another main benefit for junior riders is that the air spring fitted in the left fork leg can be adjusted perfectly to the rider's weight using a simple air pump.

REAR SUSPENSION

REAR SUSPENSION

The high quality WP XACT shock absorber connects directly to the new lightweight, cast swingarm with the same technology and shape, according to the stress lines, as the full size bikes. The shock is fully adjustable, meaning you can set the damping perfectly to suit the rider's preference and track conditions. The shock absorber allows for 185mm of rear wheel travel, providing excellent damping performance.

BRAKES

BRAKES

The 50 SX is fitted with front and rear hydraulic brakes by Formula, combined with lightweight wave discs that are easy to control even for the youngest riders. This ensures the best deceleration in all conditions.

HANDLEBAR

HANDLEBAR

A new high-quality tapered handlebar made from aluminum alloy has the perfect bend to suit the ergonomics and the highest strength. A new slide pad on the handlebar protects the rider in the event of contact. Additionally, the bike comes standard with new ODI lock-on grips, which include a vulcanized grip on the right side and a lock-on grip on the left that does not require glue or wire for mounting. The grips diameter is 5 smaller than before fitting perfectly the smaller hands of the young racers.

DECALS

DECALS

The 2021 KTM SX models feature the latest in-mold graphics, matching the factory-look orange frames and bodywork perfectly. They have a fast and aggressive style that screams READY TO RACE, leaving no doubt as to the bikes' high-performance intentions.
