50 SX



A real KTM for racers aged between about 4 and 10 years and up to a height of 130cm. This is no "toy" with dodgily built cheap components; this is a proper motorcycle that sets standards in its class for safety, child ergonomics and riding fun.

Equipped with high-quality components throughout, such as generously dimensioned suspension elements, high-quality disc brakes, a sturdy frame made from chrome-molybdenum stainless steel, alloy rims and aluminium handlebars with safety padding.

The engine is a completely new development specifically for the 50SX and excels with linear power development and innovative solutions, such as a centrifugally controlled automatic clutch that can be adjusted individually to the riding ability of the budding racer: nice and gentle for beginners, then later powerful and direct with higher revs. Another sensible option for beginners lacking in experience: the restrictor kit from the PowerParts range of accessories.
