Actually, ALLBALLS are tapered roller bearings, like trailer wheel bearings. Definately an improvement. It would be nice if the TW would take some standard industrial size, but it won't, so there really is no cheaper alternative than ALLBALLS.
Two good points! Use marine grease as the stock seals don't really seal out water very well. We are finding malternative sources of many parts that save a lot of money over Yamaha prices. It is almost impossible to R&R the steering stem without losing a ball bearing or two so the lower priced source is a good thing.I also only use marine water proof grease
I laughed last time the balls were like $5 each on the parts fiche
Mcmaster sold me a 100 for I think $6
