St1300 pan european front suspension

Postby Irideforlife » Wed May 30, 2018 10:06 pm

I have a problem. Although stripped and cleaned. The front suspension seems very hard on my pan and it almost bounces instead of absorbing the bumps. All looked ok with the bushes. Any advice

The weight of the fork oil is very important on some bikes. On K series BMWs the difference of 5 to 10 can cause that problem. Some mix the oils to get a 7.5 weight which works very well. No experience what is best on a Pan though.

Yep, oil weight affects damping and rebound which can make it appear to not soak up the bumps especially if on a patch with lots of imperfections - its like the suspension doesnt recover quick enough to absorb the next bump and it feels "hard" or "harsh"

I'd go low with the fork oil - like 5W and see how that feels then work up from there.

mixing oil gives different weights - equal parts 5w and 10w gives you 7.5W

two thirds 5w and 1 third 10w gives you 6.6W

3 quarters 5w and 1 quarter 10W gives you 6.25W

You can play around every which way...but try 5w first - then maybe 10w and see if you want something in between.

One other point - before you tighten the axle up snug pull the brakes and pump/rock on the front suspension to allow it find it optimum position - then torque it up to final setting.

How long has it been since you looked into your suspension for the last time ? I hurry to answer that after the rebuild, the suspension might have returned back to "normal" and it is quite hard by factory so perhaps you get a wrong impression that things went bad whereas everything is perfectly ok...

It was the same for me with my 1000f, bought it second hand and drove for 2 seasons and then did the front end with the 10w weight oil, it felt horribly hard and stiff. Then I rode a few miles and adapted however... these bikes are from the same era and I am sure the manual for your Pan will tell you to use ATF oil in the front, as it does for mine... don't know the weight of the ATF anyway but they feel quite watery..
