Model Description

 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 and safe.
 
ENGINE
The modern 2-stroke engine is extremely compact and with its easily controlled smooth power delivery is ideal for motocross beginners. As a result of its 3-shaft design, the crankshaft is very close to the bike's centre of gravity, which has a positive impact on the handling. Another benefit of this design is a flow optimized intake angle into the reed valve, which results in and impressive performance. Because of the multidisc automatic clutch developed by KTM, power from the engine can be very easily controlled. As a result, the KTM 50 SX combines extremely well-behaved handling with maximum riding fun. If required, the clutch can be adjusted to the rider's personal needs within minutes and with no special tools required, or to the specific requirements of each individual track. For inexperienced novices, the engine power can be reduced to 5.4 bhp using a special kit from the KTM PowerParts program.
 
FORK
The KTM 50 SX is fitted with an ultra-lightweight, fully adjustable WP XACT fork with state-of-the-art AER technology. This upside-down air fork with a 35 mm tube diameter and 205 mm of travel offers junior riders an outstanding ride, excellent damping characteristics and unrivaled directional stability. Another benefit is that it incorporates an air spring in the left fork leg, which can be adjusted to the rider's weight using a simple air fork pump.

SHOCK ABSORBER
The XACT shock absorber from WP is connected directly to the swingarm and features excellent damping characteristics. It can be adjusted to the rider's individual preferences and track conditions. The suspension travel of the KTM 50 SX is 185 mm.
