Recently changed fork seals , got a 2004 rs 125 how much oil to fill the front forks ?

Question edited for clarity.

Hi Marie

I have spent 20 minutes checking and this information doesn't seem to be mentioned online which is odd. I did find the Owner's Manual and that doesn't mention it. There appears to be no service manuals. Contact Honda Service in your country direct. Some go by CCs, some go by distance from the top of the fork leg.

This is the oil

Measure the diameter of the springs top,cut pipe(Usually stainless steel)and remove the tops of the forks,install the spacers in each fork tube and enjoy-Experiement with the lengths,typically start with 1 1/2~3 inches.....You can also change the thickness of the fork oil...The tubed method does not require higher air pressure to work....

Fluid quantity: 440 ± 2,5 cm³ (26.85 ± 0.15 cuin).

front fork oil capacity is 430cc

my Bajaj Discover 125 DTSi handlebar continously shacking while sudden pick-up of speed to 60KMPh. if i ride slow, then there is no problem. I checked Fork bend and all, everything is okay. please let me know.

change the oil seals and oil in the fork,and avoid wheelies on the bike and off road biking 

General intructions for most bikes:

Remove front wheel. Loosen fork tube clamps at top and bottom of triple clamps. Slide fork tubes out and remove. Access to seals is from top of tube. Remove cover and unscrew cap. Shop manual for specific bike is $24-$30. Will show detailed instructions.

Good luck;
