I was in the same dilemma with my steering head bearings, 900km to the nearest Yamaha dealer meant it was either $300.00 each way on a truck, all up $600.00 or put it on my trailer and tow it, all up 1800km and about $400.00 worth of Diesel. I got a price on the bearings for $60.00 so I just did them myself. In the end the non genuine bearings had a far Superior lower seal and I know they have a good quality and plenty of grease lubricating them. Still a bit annoyed that I only got 4000km out of them.
