BMW design flaw

[2StrokeDan]

Agree, the stuff that converts your plakkies into platforms is the clogger. I was on a ride where 2x XT660Z's had low fenders and 1 of them had a high fender conversion. Only one of the two low fenders got clogged and it happened to be a guy going very slowly, the mud should fling off as it comes free from under the tyre.
I believe that low fenders should stay on roadbikes.

Personally I don't think mud is the big issue here. I never had problems with mud before, but this is about CLAY, not just mud. It's the kind of stuff that collects under your shoes if you walk through it, and eventually make you about 1 inch taller than what you really are. Maybe they just had mud in the Dakar, but not the kind of black turf clay that we encounter here in places.

Ja but why design a super duper racing bike, and risk the outcome of the race,  by a design that will result in the bike being stopped in its tracks if you dont go fast enough, or be negatively affected if you happen to find the "wrong type" of mud, ie clay, we arent the only country that has clay? 


Still doesnt make sense to me. 

Why build something in that is going to cause problems if you dont need to?

Whats the massive benefit of a low fender?  I cant see any, apart from looks - maybe.

So why not just put a high fender on an off road racing bike?   Same goes for an Adventure bike.

  Cooling, a high front obstructs your radiator, plus it is bad for aerodynamics, it is bad for handling and if you ride quickly a low guard is OK in mud, no offense in many of the clay canal rides some bikes went through other "similar" bikes did not, there is an element of technique in this and Dakar riders have TECHNIQUE and SPEED

Na ek al die stront gelees het oor BMWs wat k@k is, gaan ek myne aan die brand steek en by Van Stadensbrug afspring (en vergeet van horses for courses)!

Kom kuir en ry saam met jou, en dan maak ons jou touwys. PM my en ons moet by mekaar kom. On is a lekker groep Big BMW riders in PE.
BY the way. Hartelik welkom hier oppie forum. Ek sien jy's nuut.

Hou op strooi praat oor jul bikes en gaan ry bietjie.JUll sit en kekkle hier soos n klomp vrou mense.My pa het altyd gese."As mens begin draf is en jy will all die pyne en moegeit weg he,is dit die maklikste om deur dit te druk".Dis die selfde hier.Ry net tot die mudgaurd k@k of JY.Hoopenlik die mudgaurd.

Ok whatever.

Still doesnt make sense to me though.

Not a shred of evidence exists in favour of the idea that life is serious.

[2StrokeDan]

Make a remark against BMW on this forum and see how serious some okes take life

Een outjie wil glad by n brug afspring.

Jip, myne ook. Meeste bikes het standaard die probleem.

The one with the knobblies has the low front fender.  Go figure....

Well in this case they both have DS tyres - the front bike TKC and my bike at the rear Heidi K60. The K60 being a litle more prone to collect mud than the TKC. Not sure about the meaning of your post though 

[Sláinte Mhaith]

Doesnt make sense does it?  Those Dakar bikes cant be immune to the problem - but maybe they assume there's no mud in the desert?

If its prone to clogging, even if you manage to avoid it siezing up by going fast it must at least affect the handling and performance?

True I see the sand and desert thing, but there was a hell of allot of mud as well I think stage 10 or 11 was just a mud mess and they only seemed to worry about radiators. Don't understand it just does not compute.

A low fender stop water spraying forward and blown back into your face. Someone on the forum removed his low fender from his 1200 and this was his complaint. (Grootseun with his dakar without the low fender can maybe comment) I presume this is why mx bikes have a fender that looks broken so that the tip can get low down to stop the spray from going into the air.

Take the gs dakar without the low fender again (or the shoes mentioned above), depending on the mud or clay it will only build up to a certain level and will then shear off on its own.  The clay under your shoe will not build up to say 10inches.  The maximum for this is most likely about 1inch if I could guess.  So if you have a low fender with 1 inch or more clearance you should be ok. Changing to a bigger tyre or a knobly with deeper treads might just reduce the critical gap and cause clogging.

This is my take on it.

Dint expect it to.You ride a washing machine that is moer expensive

Page 6 and the BMW still has design flaws??

[RoCky The Dog]

Yes. You looking at a bmw page when you ride a Yamaha.LoL.

  ...And that's only the front mudguard.

Nog design flaws oom Daan, vertel meer asseblief, ons wil alles weet?

Man, ek het gehoor dat party van die goed so kwaai kan ping, en dan is daar modelle wat waterpompe weggooi, en daai bekende ou flexi-flier voorvurke, en die canbus wat vir Solly Kramer so besigheid stuur, en die faainil draaifs wat nie altyd drive nie, en die paralever wat die ou groot GS se kop so in die sand in druk, en ai-ai die sidestand switches, en die HP2's wat so stof suig, en die batterye wat sonder waarskuwing dood neerslaan, die oudmodiese droee koppelaar wat geen straf kan vat nie, die vreeslik blootgestelde klepdoppe, die patetiese shopping trolley voorwiel, en natuurlik vars in die geheue is die 562 BMW's wat die Dakar begin het........maar klaarmaak is min.

Jare se kak uitdink waaraan daar nou uiting gegee word.
Praat Oom Daan, maak jou hart oop en skoon.

We use the low fender on rally bikes because it gives a lot more stability at high speeds. The high fender not only makes things more unstable, but it also increases the wind resistance and therefore top speed. This is why dakar bikes have low fenders.

HOWEVER we also take along high fenders for the simple reason that low fenders don't like thick mud; changing fenders that night if we know the next day will be a muddy one. If you look at this years Dakar footage on stage 12 you will see that ALL of the top guys changed their fenders for the day, for obvious reasons.

Having said that, a low fender is not really a problem in mud (most of the time), especially if you are moving at pace, but its not something one normally takes a risk with if you have a high fender availible and you know you will be riding in mud.

Saying it is a BMW design flaw is bullshit. Its not. 

They put the low fender on those bikes because the vast majority of BMW's sold are riding on tar roads at high speed, and this lends to the stability of the ride and lower fuel consumption. With this in mind, it would be a design flaw to have a high fender on a 1200.

To be honest, no bike is really designed for thick mud, as can be seen in the second picture where Cyril is trying to clean the crap out of his radiator at the refuelling point.


And Vaalseun, ek sien jy is a nuwe ou hierso. Careful with statements like that, the forum whores will come down on you like of a ton of bricks.
