KTM — Master Oil, Tire Pressure & OEM Part Spec Chart (7 Models)

KTM high-compression LC4c, LC4, LC8c, and LC8 engines demand shear-stable SAE 15W-50 or 10W-50 JASO MA2 full-synthetic oil (Motorex Power Synt 4T). Unlike single-plug Japanese wet sumps, KTM engines incorporate removable evacuation mesh screens alongside internal paper cartridge elements—and the 690 SMC R uses two separate paper filters plus two oil screens that must be cleaned and pre-primed during oil changes. Always note whether your KTM hydraulic system specifies glycol-based DOT 4 / DOT 5.1 versus mineral oil (Magura clutch masters on select enduro/LC4 models).
