MAINTENANCE
SERVICE PROCEDURE
PRECAUTIONS WHEN REPLACING TIRE
After tightening hub bolts (1) when replacing the tire, travel for 5 to
6 km, tighten the bolts again to settle all the contacting parts.
In particular, there are more contacting parts on the rear wheels
than on the front wheels, so it will take time for the parts to settle.
For this reason, repeat the tightening process during the first 50
hours after installation.
