Yamaha — Master Oil, Tire Pressure & OEM Part Spec Chart (120 Models)

Yamaha specifies SAE 10W-40 JASO MA2 across its Crossplane Concept engines (CP2 689cc twin, CP3 890cc triple, and CP4 998cc inline-four). Within the MAX scooter family, NMAX 125/155 and XMAX 300 run dry centrifugal CVT clutches, whereas the flagship TMAX 560 houses an oil-bathed wet multiplate clutch that strictly requires JASO MA oil and a spin-on cartridge filter. Most modern Yamaha multi-cylinder platforms share the 5GH-13440-80 M20×1.5 spin-on filter architecture; always replace the crush gasket and torque the sump bolt with a calibrated wrench to protect cast-aluminum oil pans.
