Whether crank, wheel, helical or cam gears, they all need gear oil. To minimise friction in the gearbox and reduce the pressure between the contact surfaces, gear oil is needed as an intermediate fluid that is distributed to all corners and ends of the gearbox. Gearboxes are often subjected to high loads. That's why MOTOREX has always made sure to use only the finest base oils and enriched preparations so that you can use your machines without worry.
