Best Engine Oil for Ktm 390 Duke

KTM/Motorex Oil Change kit for 250/390 engines

The KTM/Motorex Oil Change Kit is purpose-built for the 390 Duke's engine, removing the guesswork around compatibility. Motorex is KTM's factory-approved lubricant partner, and this kit includes the correct 10W-50 full synthetic oil alongside a matching filter, so you're not hunting for separate parts. It's the exact spec KTM recommends for the LC4c single-cylinder. Caveat: it costs noticeably more than generic alternatives, which may matter if you're on tight service intervals.
