About this model
About the Ktm 450 SX
The KTM 450 SX-F is a competition motocross machine that has consistently represented the pinnacle of the MX1/MXGP class. The liquid-cooled 449 cc single-cylinder DOHC engine produces around 63 hp in production trim and is engineered for maximum motocross performance, with an engine derived from KTM's factory race machines that have won multiple world championships.
The 450 SX-F is exclusively targeted at competitive MX1/MXGP class riders. It is not a road bike and is not road-registerable in most configurations. The approximately 107 kg dry weight and aggressive state of tune require riders with significant experience. Recreational off-road riders will find the 350 SX-F or 450 EXC-F a more appropriate choice.

Before you buy
What to check before buying
- The engine is tuned for intensive 30-minute race use; hard daily riding or high hours accelerates piston and valve wear significantly.
- Check valve clearances at every service; the aggressive cam profiles require frequent valve clearance inspection (every 15 moto-hours recommended).
- Inspect the air filter housing and element; a blocked air filter under dusty conditions can cause engine damage.
- Check the suspension (fork and shock) for hydraulic oil leakage; WP suspension requires annual rebuilds under regular use.
