Easy Suspension Adjustment

As always, the suspension boasts an easy tool-free setup at both ends, ensuring you chase down the podium in total control. On the rear, a hand-adjustable dual compression control allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.

Airbox

Designed to provide maximum airflow, the new air filter box is designed with precisely positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. The Twin Air filter and air filter support design feature a simple fail-proof mounting system for safe and accurate filter installation, ensuring the air filter is easily accessed, without tools, by removing the left side panel, for easy track-side maintenance.

Serviceability

The KTM 450 SMR is engineered and designed to provide riders with easy-to-access service parts, as well as suspension adjustability. This allows for faster track-side and off-season maintenance, as well as making supermoto more accessible for novice riders without pit crews. For 2026, a new threaded radiator closure allows for easier and faster opening with reduced force.
