Avant front mudguard extender & Wunderlich engine protection plate

[arrybash]

Hi,

Does anybody know if a GS Adventure fitted with Avant front mudguard extender will foul a Wunderlich engine protection plate.

I have the Avant fitted and went to fit a Wunderlich engine protection plate but they seemed very close and I was concerned they may clash when the front suspension compresses so I took the protection plate off again.

Will be interested to hear what others say.

I had the same thought when I fitted my Cymarc engine plate at the weekend. Not planning on getting the extender but not a great deal of space with the oem fender.

Out of interest, what's the quality like on the Wunderlich engine cover?

I have an Avant extender and a Cymarc touring crudcatcher on my GS and yes it is close but after a year they have never made contact!

 

[fredaroony]

I have both and it fits fine but I have a GS. Can't imagine it's different though

I have both fitted on a 2016 spec GSA LC, I've had no problems.

I bought the Wunderlich engine protection plate after reading that the Cymarc crudcatcher doesn't fit with the Avant extender. The Wunderlich engine protection plate is a lot smaller than I was expecting made from aluminium. I assume it will do the job but not a patch on the quality of stainless steel Cymarc that I had fitted to my aircooled GS.

Yeah, I thought the Wunderlich looked a bit small in the photos, so went for the Cymarc. Very good quality although the OCD side of my brain thinks its a shame the bolts aren't torx to match the rest

Is it worth getting the Avant extender as well as the engine plate?

Unless I have misunderstood Telelever, I think the front wheel effectively goes up and down at a right angle to the ground. The wheelbase reminins almost constant. So if there's light between the wheel and the crud catcher at rest, it should stay like that even when the forks compress.

I'd be surprised as the wheel is attached to the forks, so the wheel would automatically rise/fall at the angle of the forks, no?

I'm no mechanical genius mind so happy to be corrected

Yes my thoughts were the same, those allen key heads look out of place!

Yebbut, there's a gert big lever sticking out from half a metre back, and the wheel stays absolutely fixed with that, so must travel through the same half metre radius arc as the end of the lever. I had to scratch my head a bit wondering how it worked. The fork stanchions have a rose joint or similar at the top yoke, to allow them to pivot forward as the wheel moves upward.

Not sure I follow, but looking at the image on this page I'd still imagine the wheel is rising in line with the forks. Otherwise the forks would have to change angle......

Reading the explanation, the telelever significantly reduces the amount of compression relative to a 'normal' bike, so maybe that's why it can get away with what seems a small gap

They do...

My brain can't fathom that, which could be why I'm not an engineer

Got the avant and the hooters crud catcher , it seems close but they don't touch

 

[autogs]

They do...

no they dont,its still got fork tubes attached to the yokes,wheel follows line of forks just as in an ordinary bike with tele forks

Well, we'll just have to disagree then. ;-)

But... the lower yoke is attached to the lever that pivots on the engine. The front end of the lever moves in an arc. The wheel spindle is clamped at the bottom end of the fork sliders, the top end of the fork sliders are clamped by the lower yoke. Therefore the wheel spindle moves in almost the same arc as the end of the lever. I say almost, as the angle of the forks must change as the lever moves upwards as the forks compress. Unlike normal tele forks, the distance between the fork yokes changes when the wheel moves.

But I'm not not an engineer, so what do I know.
