Ktm 450 Exc-f Review
"An outstanding used buy, but service history is absolutely non-negotiable."
Used Buyer Review
The 450 EXC-F is the closest thing to a race bike with a license plate, and that's exactly what makes buying one used both exciting and nerve-wracking. These engines are genuinely outstanding — that thumper pulls hard from idle and just keeps building. But here's the thing: find out the service history before you hand over a cent. The valves need checking every 100 hours, and plenty of owners ignore that. A neglected one can cost you serious money fast. Used examples from 2019 onwards are the sweet spot. KTM sorted some of the earlier reliability gremlins by then. Check the suspension linkage bearings — they get neglected constantly — and look for play in the head bearings. The wiring harness connections are another weak point, especially if it's been ridden in the wet regularly. Budget an extra few hundred for a full fluid refresh and bearing check regardless of what the seller claims.
