13. TRIM AND SETTINGS
13.1. SAG REGULATION
In order to obtain a correct behavior of the motorcycle during the use, it is necessary to check that the suspensions
are properly calibrated with respect to the rider’s weight. To verify this, perform the following steps:
SAG MEASURE
1.
Raise the front of the motorcycle so that the front wheel is not touching the ground and the fork is fully
extended.
2.
Measure the distance between the front wheel pivot and the base of the fork sheath. (F1)
3.
Lift the rear of the bike so that the rear wheel does not touch the ground and the shock absorber is fully
extended.
4.
Measure the distance between the axis of the stand peg and the lower rear frame tube. (R1)
5.
Place the motorcycle vertically with the wheels on a flat ground.
6.
Repeat the measurements of points 2 and 4 with the rider in the driving position and wearing protective
clothing (F2 & R2)
The differences between the measurements made with and without the rider must be respectively equal to:
GP-0
GP-2
FRONT (F1-F2) =
11
÷
15mm.
REAR (F1-F2) =
18
÷
22mm.
FRONT (F1-F2) =
14
÷ 18 mm.
REAR (F1-F2) =
17
÷ 21 mm.
SUSPENSION SETTING
If the measurements are not within the ranges shown, it will be necessary to act on the suspension preloads.
FRONT SUSPENSION:
Act on the spring preload adjusters, screwing them in if the sag measurement is
higher than the indicated range. On the contrary, unscrew the register if the SAG is lower than the indicated
range.
REAR SUSPENSION:
Act on the spring preload adjustment ring nut by screwing it in case the sag
measurement is higher than the indicated range. On the contrary, unscrew the ring nut if the SAG is lower
than the indicated range.
In the event that the SAG measures do not fall within the ranges indicated through the use of the registers and the
ring nut, it will be necessary to replace the springs with a harder or softer set (see SUSPENSION chapter).
