Maxima Racing Oil — Professional 4-Stroke Maintenance, Eliminate the Risk of Critical Component Wear

Stop the "tuning guesswork" and the hassle of sourcing individual crush washers and O-rings every time you service your Yamaha. High-performance motocross engines operate under extreme heat and RPM, creating a performance gap where standard oils fail to protect. This complete oil change bundle provides a professional-grade solution, combining premium Ester-fortified synthetic oil with high-capacity filtration to ensure your engine maintains peak power throughout the entire service interval.

Every component in this kit is selected for Matched Performance and System Synergy. The Maxima Pro Plus+ full synthetic oil uses next-generation additives to maintain film thickness, protecting the integrated wet clutch and transmission gears under heavy load. Paired with a Factory Quality Hiflofiltro cartridge and a Bolt hardware kit, this system ensures a leak-free seal and superior contaminant removal that meets or exceeds original manufacturer standards for the Yamaha YZF series.

Moto-House MX Pro Tip:

When performing an oil change on your Yamaha YZ250F or YZ450F, always use a clean pick to remove the old oil filter cover O-ring and lightly coat the new one with fresh Maxima oil before installation. This prevents the O-ring from binding or tearing when you torque the cover bolts, ensuring a perfect Factory Quality seal every time.
