2019 KTM 450 SX-F

Engine & Exhaust

The 450cc engine is the ultimate powerhouse when it comes to KTM's competitive motocross range. Significantly reworked for 2019, it features even more compact dimensions and reduced weight. It is fitted with a newly designed, extremely compact single overhead camshaft cylinder head and the latest electronic fuel injection. This enables the impressive 63hp to be distributed extremely efficiently throughout the rev range. Even with its super-beneficial electric starter this model is still the lightest 450 engine on the MX market.
