Öhlins DH38 / DH38 M.1 Air Pressure

Rider Weight Ramp Up Chamber (bottom valve - pressurize first) Main Chamber (upper valve - pressurize after Ramp Up Chamber) 
50-60 kg 200-210 psi 80-95 psi
60-70 kg 210-220 psi 95-110 psi
70-80 kg 215-225 psi 110-125 psi

80-90 kg

225-230 psi 125-140 psi
90-100 kg 230-240 psi 140-155 psi
100-110 kg 240-245 psi 155-170 psi
110-120 kg 245-255 psi 170-185 psi

Important:

  • If you want to change air pressure, always adjust the Ramp Up chamber first (bottom valve) and then adjust the Main Chamber; without doing that the spring will have travel and/or balance issues.
  • Reset to original ride position: after reducing the air pressure in the main chamber, the fork need to be restored to its original travel. For instance, lowering pressure from 130 to 80 psi will lower travel. The only way to restore travel is then to pull the handlebar up while the wheel it kept to the ground and repeat the extension 10 cycles until original travel is restored.
