The NICECNC Oil Pump Gear kit solved the problem of twisted and broken plastic gears in the oil pump of 450/500/501 Austrian four-stroke dirt bikes
CNC-machined gears from aircraft-grade 7075 aluminum, which are hard-anodized in high-wear areas. These metal-upgraded gears are of high quality and have been proven to be successful in races
These metal gears just weight 58 grams, only 31 grams heavier than the plastic gears
By replacing the plastic gears with these metal ones, it eliminates the need for regular inspection, replacement, and worry about the failure of plastic gears in the engine
