Subject: Full metal sound
Hej,
Last weekend, I was driving quite hard, for a full day in conditions more
terrain than road. It was fields with tank tracks (yes it was a military
exercise field) and we where also driving in the tank tracks in the forest
and a bit in the forest without track (easy terrain though). To connect
these parts of the track, there where soft, dry, gravel roads, tempting to
high speeds (easy sliding).
Btw, it was in Sweden.
Now to my question. Now and then, the suspension would travel its full way,
like when the bottom of the tank tracks would be like long waves. This was
not very dramatic and didn't concern me much, but when I jumped to long in
these tracks, or crossed right angle the tank tracks with sharp edges ( of
course not the meter deep ones with the wave bottom), the front fork would
travel to the bottom very fast and hard, giving an almost metal sound.
Does anyone of you have an idea of what is giving the sound. Is it the fork
tubes coming to some bottom position, or is it the springs that will be
fully compressed, or is it the oil level that hits the end of the tube (all
air compressed)?
Once I got a back wheel kick, not a very nice experience when the only
contact whith the bike was the handle bars, but there was no alarming
sound.
Btw, it was not at all just problems, we had a long day of realy fun
driving and no damage to the the bike.
