Hello dear Kawafriends… for a few days now I find, when I drive over Kopfsteinplaster, that there is a blow on the handlebar..You can feel it right… on a straight track everything is normal. Now both dampers completely removed and brought to the workshop, these should take a look. Today call from the same.Yes the diving tube has Riefen, the springs are still good.Woln for both dampers with new ÖL and the Simmering seals 500 Euro. Have an old Kawa El 250 B year 1992 has now almost 54,000 KM down.. Actually I hang on to the part. What do you mean for the price…is here in Berlin a brand workshop. Gruss Dettilein123
