New to the Touring Bikes and know there is a grease fitting on the front steering stem of the new bike. How much and what kind? MOCO's owners manual says use their special purpose grease for steering head bearings. Looking around the local auto parts store the other day and saw some Mobile 1 synthetic grease that looked like it was thicck enough to stand up to hwarm temperatures without oozing out the front end. What are you guys using?
