RFX Pro Series Oil Filter Cover - Green for KAWASAKI KX 450, KX 450 X, KXF 450 2019-2027

RFX offers this Pro Series oil filter cover for KAWASAKI KX 450, KX 450 X, KXF 450 2019-2027. It closes the oil filter housing on the engine case, in place of the stock cover.

Why choose a machined oil filter cover?

• 7075-T6 aluminium keeps its shape under heat and oil pressure, so the seal lasts.
• Enlarged oil passage for better flow.
• The hollow design saves weight without weakening it.
• It takes rock hits and crashes better than the stock cover.

Why choose RFX?

RFX designs machined parts for motocross and enduro. The Pro Series range is machined from solid billet and anodised, so the colour stands up to hot oil and pressure washing.

When should the cover be replaced?

When it is cracked, warped, has a damaged thread or still weeps with a new O-ring. The O-ring itself should be changed at every oil change.

Specifications and fitting tips

• Material: anodised 7075-T6 aluminium
• Colour: green
• Fits with the stock O-rings
• Manufacturer part number: FXFC2040099GN

Cross-Mania tip: fit it at an oil change with a new filter and new O-rings, and tighten the bolts in a cross pattern to the workshop manual torque: aluminium does not like overtightening.
