Steering head ball bearings
have been the weak spot in the area of handling on the RD series
Yamahas. The cure is now here in the form of tapered roller bearings.
Simply push out the stock ball bearing races and push in these long
lasting, rigid tapered rollers.
# NPTR - Fits RD250 through 400 (except '79), XS360/400, Pre-'79
# NPTZ - Fits RZ350
We also have tapered
roller bearings for many more models, including the XJ550, FJ600,
FZ600, XJ650, XJ750 and XZ550R Vision. Please call for further details.
