Ride Reports / Namibia February 2017
« on: April 16, 2017, 08:14:46 am »
2 Friends, 5.5 days available only for this trip. 4100km. What a trip
My adventure riding friend Ian van der Berg , have been dreaming about a bike trip to Namibia for the last 2 years. In 2016 I visited Namibia with my family in our 4x4 , so had a good idea of where and what I would like to show him on such a trip. During December Ian really started nagging me to do a trip. Both of us being business owners with me really having limited time to go on bike trips, started talking about March 2017 for a trip to Namibia. Yet every week in March started filling up with either family or other business responsibilities until I had to call of March as a no go for a trip to Namibia.
It was the second week of February during peak hour traffic on a Monday morning when after phoning my wife and getting the all clear with no other responsibilities for the upcoming week , that I phoned Ian and asked him if it would be possible for him to get his bike prepped and ready to leave in 2 days time for his dream trip to Namibia. Both our bikes still needed new tyres and in  a haste 2x scott stearing dampers was also ordered and fitted by Off-road cycles in Pretoria
Ian only dropped of my bike Tuesday night at about 9pm , after which I still needed to pack my bike.
We arranged to depart the next day at 1pm from my business in Primrose

820km later whe arrived in Upington at 9pm and went looking for a b&b for the night.
Next morning departed Upington at 6am after a 5am breakfast at b&b , direction Nakop border post

Next stop was Canyon road house for a quick snack

Then Fish river canyon

The we headed still North to Seeheim hotel for late Lunch

We wanted to still make it to Beta but eventually run out of time and energy and found a nice camp for the night on a farm about 80km before beta

Friday morning started bright and early
Breakfast at Beta and then arrived at Sesriem campsite. After a quick visit to Sesriem canyon we arranged a lift to Sossusvlei as bikes are not allowed to go there.

Saturday morning started heading back south in direction of Aus. But first we had a meeting with the famous sand roads of the D707

Eventually made it to Aus. After having a quick lunch there was still enough time and we decided to do a quick dash to Luderitz and Kolmanskop

Kolmanskop was unfortunately already closed so we could only get pictures from a distance
Headed back to Aus to camp for the night

Sunday morning decided to travel via Rosh pina to Noordoewer back into RSA

Stopped for lunch in springbok and then pofadder
At Pofadder I noticed Ians rear shock was bent
We slowly limped on to Augrabies. About 500 meters before Augrabies campsite the rear shock snapped. BMW germany engineers happened to be following us into Augrabies as this happened
They immediately offered assistance in transporting Ian's bike back to Jhb

BMW germany was busy with cooling testing of the new M5 in the Northern cape. They strictly prohibited us of taking any photos of the test vehicles

Monday morning I had to ride home alone for the second time on a trip with Ian (previous trip he fell and broke his shoulder at 20km/h on West coast)
This was one amazing trip.
We managed to do and see so much in such a short time.
I would encourage all Adventure bike riders to at least experience Namibia once in your life.
You wont be sorry

BMW 1200/ADV / Re: Heidenau tyre stability problems on 1200gs adventure

My only conclusion so far is that the 140 rear and the higher profile compared to the standard tyres for the GS1200 Adv is maybe a problem. Usualy the rule is small bikes narrow tyres etc. the 800 GS the 140 is perfect. I used to race superbikes and experienced a similar problem there. Dunlop a few years ago brought out a new rear tyre ,but it had a higher profile. It caused the most nervewrecking headshakes and wobbles on the bike. By lowering your rear suspension with a few millimeters only the problem was solved. The theory was that the chassis and suspension was designed to be stable with a certain dimension tyre. On my 2009 GS Adventure with its electronic suspension , the rear suspension got raised when I changed my suspension setting to rider + baggage setting for the Eco event. I wish I had tried to go back to my normal suspension settings while loaded on this trip to see for a possible difference.

Is the wobbling feeling not maybe normal with most knobblies? I have only owned my GS1200 Adv since May 2009. I did my first 1000km running on the standard Metzeler Karoos I bought the bike with and then replaced them with the Maxis which I have been riding on up until 10 days ago before fitting the Heidi's. I only refitted my karoos before last years eco and removed them straight after again. So have I been used  to the high speed stability of the Maxis on tar and have forgotten what knobblies on tar feels like.
Maybe after reading all the comments there is a compromise between using a 30/70 tar biased tyre compared to a knobblie.

Now the big question? Which tyre for when and where? Or is mud the only real surface where the knobblie far outway its benefits compared to a anakee for instance for somebody like me doing about 50% of my weekend riding on good gravel farm roads.

Thanks. Will maybe have the dealer reset the tyres. I immediately after fitment thought the front heidi is the wrong way around and checked the arrows to confirm.

Yes. There were no vibrations at speed indicating unbalanced wheels.

I also found I had to adjust my electronic suspension to the max etc. sport setting for tar and hard off-road on gravel which did make a small difference. I am convinced it is the 140 rear tyre size instead of the normal 150 rear tyre size causing the instability problems. As it is a knobbly tyre I did expect some movements compared to a road biased tyre , but it actualy gave me goosebumps at times feeling out of control on tar and gravel. Low speed off road they worked perfect.

 >:( Last year at the BMW GS Eco event I noticed a lot of 1200 GS's fitted with Heidenau tyres. I completed last years event on Metzeler karoos which came fitted standard on my new GS 1200 Adventure purchased about 3 months earlier. My rear Metzeler karoo just made it home with about no tread left after less than 4000km's on the clock. I came home and could not find any stock of Heidenau's at that stage and fitted a set of Maxis with the same tread pattern as anakee's.
My rear maxi tyre was due for replacement and I decided to try the Heidenau's after reading good reports about them. I could only find a 140 rear tyre as they are not available in 150 rear size.

I could only fit the tyres 2 days prior to the Eco Challenge. I immediatley noticed a bit of a whobble at speeds over 120 km/h and even during hard braking unloaded.
My bike was loaded very light for the Eco challenge yet I felt very nervous traveling at 140km/h on the highway. On the fast gravel road leading into Smithfield most of my group was traveling comfortably  at speeds of 120-140km/h on anakees and Continental Knobblies , yet I felt extremely nervous and had a serious head shake at only 90km/h.
Has anybody else experienced similar reactions on the heidenau's on a 1200Gs?
Tyre presure on gravel was1.4bar front and 1.8bar rear and on tar 2.4bar front and 2.8bar rear.
