Measure distance from center of rear wheel to rear fender in riding condition
The measurement procedure is as follows:
1.The rider rides the motorcycle (engine does not start)
2.Righten the motorcycle so that the center of the tire is
perpendicular to the ground.
3.Measure the distance from the center of the rear axle of the
motorcycle to "point 1" and record it as "A3".
4.The rider uses side stand to support the motorcycle and leave
the seat cushion.
Calculate the difference between "A1" and "A2" and denote it
as "D2".
The D2 value of 21 TT125 is shown as follows,

If "D2" measured by the customer is lower than the factory
value, the spring preload can be lowered appropriately; If
measured "D2" is higher than the factory value, the spring
preload can be adjusted higher; If "D2" is far less than the
factory value, it is necessary to replace the spring with a lower
hardness; If "D2" is much greater than the factory value, it is
necessary to replace the spring with a greater hardness.
Adjust the spring preload of the rear shock
