Faulty Ohlins?

Coming back from Bristol earlier I started to notice the ride was really bumpy, I put it down to poor road surface but it seemed to get worse over time until it started becoming a real bone shaker! Rear suspension seems to have dropped as the headlight is way too high and people keep flashing me up. Quite painful on the back and bum which is not like this bike at all especially with the comfort seat it's always been a pleasure to ride even all day without any pains.

Is this potentially a problem with the suspension or have I maybe done something stupid in the settings by accident? Anyone else experienced this? The bike is less than 5 months old with only 2,300 miles on the clock so not expecting to have anything go wrong with it at this stage, would be really disappointing if it has to go back for warranty work :-/

Sounds like you've messed with the settings.... put them back to standard. It will be in the owners manual.

I'm ashamed to say I pretty much left all the settings as standard from when it was new and never bothered to get the user manual out and fiddle with the settings to see what they all do (other than to change from modes A, B, C & D... I'd played with changing the different modes as that's pretty straight forward but each mode is able to be modified and customized in excruciating details so I lust left it on Mode B).

However I got the user manual out last night and familiarized myself with all the menu options. Now I know how the menu works I'm pretty sure I can't have put the suspension to its hardest setting by mistake. I've reset everything to factory settings and put it in mode D (least aggressive throttle, most traction control, softest suspension setting) and it's still a bone shaker.

Something changed half way back from Bristol. Don't forget the rear is sitting very low now and my headlight is dazzling everyone, I was getting flashed up constantly. I'm convinced it's broken. But no error messages or lights on the dashboard Thinking

I called the dealer today but they're closed (someone on divert to a mobile answered and told me to ring tomorrow). I'll probably just email them now...

Also does anyone know if the switchgear buttons are supposed to be illuminated? I thought I remembered reading/hearing in one of the MCN reviews that they were but mine are now. Wondering if a wire came loose when they installed the heated grips at the dealer before I picked the bike up Thinking

Is this supposed to be a joke thread?

No.

I'm the joke, not the thread.

I have. Can't see much. No evidence of oil leaking. Not even sure if they're air shocks? Got to be honest I'm not sure I'd be able to tell the difference between a good shock and a collapsed one unless I had them on the bench side by side.

I'm fairly practical but by no means a mechanic Sad

The spring is in tact yes, that's fine. But if the shock absorber has leaked oil or air and not doing its job I'm not sure I'd be able to tell :-/

Also as it's semi active suspension may be there's no mechanical fault but the control unit isn't levelling it correctly and has slammed it to the floor? I really don't know I'm clutching at straws here but that happened to an A8 I had once with self levelling suspension.

Leaking oil or gas out of the damper wouldn't normally affect ride height, that's set by the spring. You'd just get a ride like a pogo-stick. Unless there is a remote ride-height adjustment that's crapped out?

So unless there is a crapped out remote ride height adjuster, something is physically broken. Either the spring, the shock mountings or part of the unitrak assembly.

I wouldn't ride it until you've found out what's wrong.

See this, its a shock on its lowest preload setting. Either it was adjusted or the lock rings are loose. Thats why you are blinding people.

I didn't ask for details, you just didn't give any.

Does that explain why it's such a bloody rough ride? My arse is still hurting it was rattling me to pieces. Clearly I have no idea what I'm talking about but my uneducated guess would be if anything having it in this position would make it MORE or a plush ride as the spring is at its softest setting? Or could it be it's bottoming out?

semi actively putting loads of rebound in to compensate for it having insufficient sag, then the shock ends up compressed. Set the spring so it sags 35mm when you sit on it and try again.

If it's electronically controlled it could be a number of things.
Wire/s, connectors, relays, controllers, motor/servo and cetera.
Dealer should get it.
Unless you fancy going through the whole circuit unplugging and plugging to ensure the connection is at least pushed in properly.
