01. Engine & Exhaust
The high performance 2-stroke engine is extremely compact and powerful, setting the standard in the highly competitive 50 cc class. Its 3-shaft design positions the crankshaft very close to the center of gravity, offering exceptional handling. This design provides a flow-optimized intake angle into the reed valve, which results in impressive performance across the rpm range. Orange anodized CNC machined aluminum clutch and ignition covers provide excellent heat dissipation, durability and, of course, highlight this machine's racing DNA. The multidisc automatic clutch developed by KTM provides controllable acceleration and makes riding this motorcycle as easy as twisting the throttle. The KTM 50 SX FACTORY EDITION features a special clutch configuration for enhanced power delivery, combining extremely agile handling with maximum performance. The clutch can also be easily adjusted to the rider's personal needs or the specific requirements of each individual track within minutes and with no special tools required. A reworked carburetor setting in conjunction with the new engine set up works together with a smaller rear sprocket which makes the bike even faster.
Developed by KTM, the centrifugal multi-disc automatic clutch has been specifically tuned for the 50 SX FACTORY EDITION. It provides more efficient acceleration and still makes riding this motorcycle the easiest thing in the world. It can be additionally adjusted to the specific requirements of the track and the rider in minutes and without any special tools.
Like the big KTM bikes, the 50 SX FACTORY EDITION 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.
The FMF Powercore 2 silencer and FMF Fatty pipe come standard on the KTM 50 SX FACTORY EDITION and provide an optimized low to mid-range power curve while looking incredible thanks to the nickel-plated, stainless, polished surface of the pipe and the high-grade, pressed, anodized aluminum silencer body. Rich 2-stroke sounds and the Factory appearance are assured with the FMF full system.
