Hy guys,

My 2015 Trophy's - Front end/Steering suddenly became sensitive/loose after 22000km.

This is noticeable at very low, low and very high speeds - tar or gravel.

Tyre pressures/wear is not the issue.

Any advice would be appreciated.

Will visit my dealer on Monday

Thanx
Gert

Paar goed wat jy na kan kyk.

Eerstens is die vurke recall gedoen.

Jy het dalk n balance weight verloor. Op verskillende spoed maak dit n verskil.

Kyk of jou speke almal vas is. Gebruik n skroewedraaier en tik elke speek.
Skerp geluid is goed. Dowwe geluid beteken hy is los.

Dalk is steering dampener los.

Check if the right side connection of the steering damper (where it attaches to the fork) is still on tight.

My first LC wear was the issue.  I rode about 350 kms with a howling gale from the one side.  Did the eco and had a few scary wobbles, blamed the sand.  On the ride home to Durban I could not go over 150 without a scary wobble.

I took it straight to Ryder, absolutely no sight of uneven wear, on the fairly newish tyre, they borrowed a front wheel (with permission from the owner) from a bike having a service and I took it for a spin, absolutely immediate difference. 

so I replaced the front.

Hi guys, thanks to all for your inputs, I will look into it. Rode on Sunday again and nearly lost the bike doing around 150km/h in a bend hitting a slight bump in the road - scary..

Forgive being a nuisance, but has the issue been sorted yet ?
What was the prognosis & what did you have to do to carry out the repair ?

Sorry for the late reply - no not sorted yet - we are playing around with the back suspension settings - keep in mind it's a Trophy edition - no electronic suspension. It feels a little better but we are not addressing the problem. I still think the problem is in the front - feels like suspension/damping/steering related. Even when going over a bump when cornering at very low speed I can feel the diffs in handling - feels shaky and nervous...the moment the front wheel hits the bump I feel the problem before it can translate to the back - also riding in a straight line when I deliberately move the handle bars it is more sensitive than before...I think steering damper but the clever people say if it's not leaking it's fine?

Maybe it's not leaking because it has already leaked all it can and is now without anything more to leak.

Disconnect one end and try to move the damper on its own by hand.  If it moves freely without much resistance, then you have found the fault.

Also if you turn the steering in full motion as fast as you can and aggressively side to side you will definately feel resistance.

Hi guys, all I can say is after fitting a new set of tyres ( Karoo Streets ) the bike handles 90 % better - as we all know fresh rubber is always a good thing - not sure if that was the problem..... I like the Streets.... better off road and about the same onroad

Hi all

My 2013 bike is behaving similarly as above.

In short the steering bar moves by it self from left to wright and back in a repeating pattern which are triggered by the load / speed combination.
With myself (and the empty top box) on the bike this behavior starts at plus minus 190 and becomes more violent as the needle is pushed further north.
With myself, top box and two panniers on the bike this behavior starts at plus minus 160.
I always weigh the panniers and balance the loads, max load 17 kg each (including pannier).
This behavior is also noticeable when heavy braking is used at medium to high speeds.

The brakes pads have been changed and their are no signs of uneven braking.
I went back to a standard GSA screen, had a large Puig on the bike before.
This resulted in a large improvement in the handling.

Now i want to get the lacing checked (and adjusted) for a high accuracy rim.
Any suggestion of really good people around whom i can I approach to get this done?

Regards
Marius

Does you 2013 have a steering dampener?
If not, maybe start there.

Give Offroad Cycles in Pretoria a call, as I know they do this.
Their quality is outstanding by what I've seen, hell, they even stock various new wheels they build.
Mind, they're not a BMW-only outlet so some laarny types perhaps may not like this, but they do know their stuff.

You know, I am really baffled why this always is mentioned when Offroad Cycles is concerned!
Beserker was in Pretoria last weekend (he's a Capie) so we went there, for a coffee.
The reason was he'd never been been there before, he wanted to see what's what.
He remarked that they stock more goodies than all the offroad shops in Cape Town together, in fact I had to pry him out of there to go home!
They do have a lot, and I've never thought I've been robbed there, on the contrary actually.
Good coffee too!  :thumleft:


Oh, before Chris from die Vliegende Baksteen (he's in CT) will chirp in here: I will still come for coffee at your pozzie when I'll be there bru, no worries  :P

Hi guys

Thanks for responding.  :thumleft:

Steering damper - The bike is fitted a Hy-Pro adjustable unit which i now set at nine clicks turned in from fully open / loose (adjustment range = 23 clicks). Increasing the number of clicks makes matters worse as the movement is transferred into the bike frame.

Will give Offroad Cylces a call.
