Segment: Enduro/Offroad

The hugely successful 450 SX-F powerhouse has extremely compact dimensions, strong performance throughout the rev range and a low weight; this is the lightest 450 engine on the MX market.

But that doesn’t mean it’s not a heavyweight in terms of muscle. Fitted with a single overhead camshaft cylinder head and the latest electronic fuel injection, it pumps out an unrivaled 62hp. With KTM’s engineers working tirelessly to increase service intervals, this super stroker has the latest engine management technology on board and confidently shoots both amateurs and pros to the top of their time sheets.
