The shock absorber compresses under pressure and rebounds to recover its original
length. The compression dampening is the setting that determines how fast or slow it
is compressed. The rebound dampening (or bounce) is the setting that determines how
fast or slow it stretches.
Getting the correct suspension preload is essential for good performance of the vehicle.
The sag is the cushion stroke caused by the rider’s weight while seated on the
vehicle in their normal position.
Each rider must adjust the sag under their weight by changing the spring’s preload. It is
recommended that the shock stroke be set at 10-15 mm for normal riding and 15-20 mm
if going downhill.
Recommendations for the shock absorber:
Do not try to remove the shock absorber. Visit a Bultaco Motors Dealer if it
does not operate normally.. Damage caused by misuse or removal will void the
warranty.
The shock absorber is preloaded with 5.5 to 6.8 bar (80-100psi). To prevent air
leaks do not try to remove the valve.
If you have been through a muddy trail, carefully clean the main shaft, dust cover
and rubber stopper.
