KTM 450 EXC-F 2025

The KTM 450 EXC 2025 impresses as a reliable enduro bike all-rounder that scores particularly well on longer rides with its smooth and powerful engine characteristics.

wide torque curve forgives many riding errors

always clean reponsiveness

the engine easily shakes the power out of its sleeve and is never really challenged. Hard-working riders who put in long hours will probably be happier with it than with the more radical 250cc or 350cc models

smooth, quiet power delivery

comparatively low fuel consumption

practical maintenance intervals

good traction

pleasantly controllable engine brake

The engine heats up quickly on very slow sections

slightly more demanding on downhill sections than the small displacements or 2-Strokes

sound is a little too intrusive in sensitive regions

tedious throttling requires new mapping in the ECU
