    As gearbox oil is not changed too often, a premium product offers improved protection, my gearbox and gear changes continue to be nice and smooth.

    Amazing gear box oil. After change of the oil the feel of gearing is nice and smooth again. Recommended with “R-Magic Shift “Color” Collar” and you will get smooth gearing and extra steely feel.
