Checking and adjusting steering head bearing *
Check steering head bearing for play periodicaly. To check this put motorcy-
cle on a stand so that the front wheel is off the ground. Now try to move the
fork forward and backward. To adjust, loosen the five clamp screws [4] of the
top triple clamp and turn steering stem bolt clockwise [5] until there is no
more play. Don’t tighten the steering stem bolt all the way, otherwise the bear-
ings will be damaged. With a plastic hammer, lightly rap on the triple clamp
to avoid tension. Re-tighten the five clamp screws with 20 Nm.
IF THE STEERING HEAD BEARING IS NOT ADJUSTED TO BE FREE OF PLAY, THE
MOTOR-CYCLE WILL SHOW AN UNSTEADY DRIVING PERFORMANCE AND CAN GET
OUT OF CONTROL.
IF YOU DRIVE WITH PLAY IN THE STEERING HEAD BEARING FOR LONGER PERI-
ODS, FIRST THE BEARINGS AND THEN THE BEARING SEATS IN THE FRAME WILL
BE DESTROYED.
At least once a year, the steering head bearings should be greased.
