Denzo's contact? Sorting out Hex Adv front end.

[er-minio]

I spoke with Denzo a few years ago on the phone, but then lost his contact number. Anyone has it (via MP ok)?
I'm trying to sort out an issue with the front end of my GS and I think this is wildly beyond what I can do (with mates' support) or even understand, and might make sense to bring the bike to him.


Don't remember if I described the issue before (definitely posted on another forum I am part of) here.
Trying to keep it short: my bike front end has become increasingly stiff in compression.
If you get to a sharp bump during cornering the front wheel will skip a bit to the side (not massively confidence inspiring). Again on asphalt junctions (bridge joints, etc.) the bike has a very hard response.
It has been going on for quite a while, I think it's getting worse now.

I've had the shocks checked last year and did another SAG set-up and had them a bit "softer" than my usual (considering an on asphalt and off sometimes).
Last weekend I used the bike and opened the compression a couple of clicks, no massive change. Bike is on Ohlins TTX front and back.

I've had issues with the front end (bike unstable at speed coming out of corners) years ago and it ended up being the Telelever joint deformed and affecting the front suspension movement. I suspect it could be the same.
Additionally, if I push the bike holding the front brake you can feel a "click" sort of movement. This happens with both the wheel in straight position or completely on one side or another. Could be steering bearings. No idea.

Clicking noise is not coming from the brakes.

Your front end click will almost certainly be the front pads knocking in the calipers as the disks get clamped up and the wheel rotates slightly under shock travel. It’s subtle but you can hear and feel it.

 

[er-minio]

I know. You are not the first to suggest that. And it would make sense.

I doubt it’s that, because the tactual feeling is something I never felt before, and had this bike for over 60k miles.

The proof to that could be to put chocks in front of the front wheel and repeat the movement/shake. Good luck with your investigation.

I am making loads of mental notes for the next few years for my bike. This is a cool forum with loads of mechanically minded people that give food for thoughts! Sometimes comments are entertaining, meaning strange theories, but that's life I guess haha
(just a general remark over a morning cup of coffee, this is not referring to anyone in particular, ok?)

I spoke with Lukasz and I'll be there Friday for him to have a look at the bike!

I would say it's worth servicing the shocks anyway. BMW suspension has a habit of failing without warning. I had mine serviced proactively by Licasz at 30k miles

 

[er-minio]

They've been serviced not too many miles ago. But he'll check that too.
It's a pair of Ohlins TTX. None of my bikes are on OEM shocks
It's the only money I spend on modifications.

I serviced them twice. To be fair, this last service was prompted because the front shock lost all its damping (while I was traveling to Italy) and started leaking and it has been rebuilt.
I've done very little miles on the bike since then.

Forgot to update: at the end the front shock was toast and on spring only. Second time in its lifetime.
Lucasz did a full service + fork seals, quick and perfect job. A pleasure.

Did you have to buy new shock or was Lucasz able to rebuild it for you?

 

[er-minio]

No, he did it.
