The new airbox on the KTM 450 EXC-F SIX DAYS has been completely reworked to ensure better flow dynamics, resulting in optimal power and throttle response. Despite the obvious performance enhancements, the new design also offers maximum protection against soiling of the air filter. The large twin-air air filter is mounted on a cleverly designed stiff cage that minimizes incorrect installation. As found on previous models, filter maintenance is quick and easy and does not require tools – a standard, original feature from KTM.
