Good Morning/Evening All,

Coming over from the f800riders forum, seems most of the traffic has been diverted to this site. Just purchased a 19' F850GS, owned an 08' F800GS a while back and really like the changes so far.

Most definitely not in stock. Delivery indicated as 7 to 14 days.
I'm in no rush though.
Modifications, Accessories, and Appearance / Wunderlich Marathon
« Last post by FEL111 on July 17, 2019, 09:24:27 AM »
Hi all, I received my Wunderlich Marathon today. I found it very difficult to choose a screen as thereís a mix of feedback on most, other than the Madstad setup which is quite expensive (and aesthetically doesnít look great to me). I also couldnít find a Piugi or Givi distributor in Australia and places like Revzilla wouldnít ship it to Australia.

So I decided to get the Marathon as it was locally available, in stock, from a reputable brand and relatively well priced.

Iíve installed it as per pics, but yet to test ride. Iíll comment later on how it goes. But Iím also posting a side-by-side picture of it against the original 850gs screen. Iíve never owned a bike with a windscreen before and Iíve found the turbulence caused by the factory screen to be the main flaw of this bike - together with the noise from the Michelin Anakee 3 tires.

I also bought the BMW GS Carbon helmet which is an adventure helmet. Iíd sold my old helmets, so Iím not sure if itís the screen plus helmet, bit Iím finding even with earplugs thereís too much wind noise.

If the screen alone doesnít do the trick, Iíll end up getting the newly released Wunderlich screen adjuster which is similar in function to the Madstad adjuster but about half the price.

Thanks for you helpful comments.

Last saturday tested the Africa Twin. As expected it is a superb machine. Just perfect for my size. Now I am trying to find a F800 to ompare. Not easy because dealers only have F850 as test bikes. To difficult my choice, I am told by some friends that would be better to go for Gs1200. :034:  Still  need to ride both.

About sourcing it from uk, it is no so simple (to rideback) because of insurance.
Other drawback is the rust condition as the salty roads are to agressive (the same in northern countries).
I am not buiying to sell in a short term.

Hi Moby,
funnily enough, I was in the same boat as you.

I had a 2013 CB500X, Faultless,it had just passed its MOT and put it for sale.
Surprised I got what I wanted for it as It had been upgraded quite a bit with this and That.
So Drove an 800 GT se, didn't like it at all due to the lean over position but only went in due to the 0% offer but kind of sussed why they are on 0% as nobody wants them?

Then Test drove an 850 GSA, Dealer in Town was very helpful and I either fancied something like this or the Tracer GT and told them so.

So to cut a long story short I picked up an 850GS Sport with 700 miles on it on Saturday.
Feels larger of course than the cb500X but it has the poke that it didn't have.
2 year Bumper to Bumper warranty and they serviced it before I got it.
GSA felt massive and for the majority of my rides a 15-liter tank which just now gives 65+mpg and 70 if Im careful is perfectly fine for commuting with a grin.

With all its bits n bobs its certainly better and of course far more expensive but I do like it.

you tax and register as normal,Claim tax back they send you a cheque but insure as normal. Just get a long MOT if its over 3 years old
you can use your Portugal license as long as you dont stay longer than a year as so far we are still in the E.U, worth checking if you can switch the clocks from miles to KMs

Just taken the plunge and ordered one from Motor Works BMW in the UK. £109 inc' delivery.
The linking tube at the top of the mount also looks just perfect for you guys looking to create a GPS mounting option.

I just wanted to share a great phone mount option I found, using the BMW GPS dock - i donít have a BMW GPS.

It only cost me USD 28, and was delivered in just over a week. It has a perfect, firm fit onto the dock, locks in place and uses the factory dock power to provide 2x USB ports. For clarity, thatís NOT not using the 12v accessory port (which remains free).

I think you are right about dropping a tooth on the front sprocket, I'm usually finding 4th gear is best for cruising on smaller roads, sixth is only usable for motorways. I realy need to rev it higher to get the engine above 4000 and the torque dip at about 3500, my normal engine speed. Don't forget my bike is the 750 and has quite a bit less top end power to the 850 (curse BMW for strangling the 750 so unnecessarily) but the sales brochure indicated almost identical power/torque curves up to 4000.
I have seen an article in Italian for a retune which removes the torque dip and in stage 1 gives the same power as the 850. I'll contact Hilltop tuning to see if they can do this in the UK.

I only have a little over 1000 kms on my F850GSA compared to the nearly 60,000 I put on my F800GS. I really enjoyed the 800 in the ten years I rode it, I put it through a lot and had it accessorized to nearly be a GSA. The new 850GSA requires a lot less stuff to get it to what I want it to be since so much of what I added to the 800 was on the 850 from the factory with the premium package and the GSA extras in general. What I've really noticed though is how much nicer the GSA is to ride. The engine, although only having 10 more hp, is much livelier and seems to pull harder from down low up to speed. The bike is way more steady on the road - where the 800 seems light on the front end and wants to dance around at highway speeds, the 850 is solid yet without being heavy to steer. Overall the 850 just seems way more refined, which it should be given the ten years difference between them. And of course the modern electronics and such is a massive game changer between the two. I can't give a fair evaluation of fuel economy or range yet on the 850 as it's still settling in and I just need more data to compare. My 800 with the Camel tank added gave me a reliable 400 - 450 km range. So long as I can come close to that with the 850, I'll be happy.

I am finding that the gearing might benefit from a change down a tooth on the front sprocket just as the 800 did to make it more workable in slow going. There seems to be plenty of top end so I don't see it hurting highway riding doing so.
