Front forks diving when braking slowly
When I am braking when travelling slowly, I get a slight diving sensation then release , then diving again,(only slightly). Someone said my springs are gone. Any ideas. I got the oil replaced!

Thanks

Which model/year/mileage?

But note that all BMW's are soft in the front end, mostly due to the long travel forks, and some dive is the nature of the beast.

Which oil/weight?

Progressive Suspension makes excellent fork springs for most Beemers. Recommended.

Rereading the question, it actually sounds like the brake disk is warped. That could account for an on-off-on sensation.

It is an F650GS Dakar 2003.

If it was the disc, wouldn't I feel a vibration when braking at every speed?

Many thanks
Andrew

Not necessarily - if it's only slightly out, you might not. Higher speed makes the pulses so close together they blend.

COULD also be a badly glazed spot, or a spot that's got oil on it at some time, which would give the same feeling.

Get it checked by a shop, they should be able to tell you easily.

Another possability is that your springs are too soft for the weight on the bike. Most bikes are set up for people 180-190 max. An average person plus extra gear can go over that easy. The springs may also be worn out if they are very old. Just a couple of things to think about if the brake rotor is not the problem.

Here's an interesting article on possible causes, problems. It's for cars, so not perfectly applicable, but good nevertheless. I think the basic info is excellent. Very interesting reading about the break-in procedure for disks and pads.
