2011 KTM 450 SX-F

When searching for maximum power, there is no better option than the KTM 450 SX-F.  The well proven DOHC engine, with four magazine shootout titles in 2010, has only slight changes as it was continuously developed and then refined over the last few years.  The package for 2011 with a new chassis will be able to play to its strengths even better.

CARBURETOR-

The engine of the 450 SX-F is powered by a 41mm Keihin FCR caburetor.  The integrated acceleration pump secures spontaneous and powerful performance.

CLUTCH-

The 2010 refined clutch had a strengthened basket design for the high power delivery of this engine.  The hydraulic clutch operation is silky smooth and low maintenance.

GEARBOX-

The 5-speed gearbox developed for 2010 suits most track conditions perfectly.

EXHAUST SYSTEM-

The superlight titanium exhaust header pipe and the innovative Header Pipe Resonator System (HPRS) in combination with the new silencer provide top engine performance with a very low noise level.

E-STARTER-

The fact that an electric start can be of enormouse advantage during a motocross heat race is undeniable.  Stefan Everts was skeptical at the beginning, but today states “I would not want to ride a bike without E-start again, doesn’t matter if it is for racing or just for fun!”
