Road test ,24hr on motorways.
Hi
Last saturday I was finely off to Normandy France to visit the D-Day beaches and all the museums.
Round trip from Oslo Norway 4500 km.
Took it easy the way down 2 and a half day,stayed over night in Germany and one night in Belgium.
Riding was all done on the motorways\autobahn ,free off charge in all the countries exept France,wher you have to pay.
The set up was my F800gs with following mods:
Bmw hand gaurds,with the highest spoilers
Bmw original sumpguard.
Bmw original luggage
60l waterproff bag ,strapped to the bike behind me,across the seat and the luggage boxes.
average crusing speed 120-130 km pr\hr,burst to 160 for a few km at the time.
After I have done what I came for I decided to go home in one go,took off at 0820 from Bayaux Normanry France and arrived in Oslo Norway 10:00,the next morning
2100km\1300 miles in 26 hr,including 55minutes ferry crossing from Germany to Denmark +30minutes waiting for the ferry.
That is the longest trip in 24hr I have ever done.
Findings and experience:
Driving above 100km pr hr has a big effect on the rider in windy condition,and I was very windy at times,the bike felt a little light but behaved ok at speeds over 100km\hr but the rider gets a sore neck\strained muscle in the neck.
You really have to keep on to the handlebars,when going fast in windy condition,and I mean real hard.
My opinion is that the bike could use a little more meat on the bones for extedend motorway crusing at high speed,was expected and confirmed by experience.
The original windshield is of no use,but to keep the bugs off the speedo\computer assembely.
Running trough the night on head lights for the first time ,and found the lights to be to be good, better when I took time to change my lightly darkend visor to a clear one
Cant see any reason to spend any money on extra lights,they worked fine.
My major consern was handlebar vibration,it got so bad that I could hardley move my fingers on the left hand and hurt like shit too,the reason was the new hand guards,when you install the new guards you have to take away the heavy bar ends,they will be changed to som small flimpsy ends made of aluminum and not from brass as the original.
The combined weight of the flimpsy bar ends and the stainless tubing \and plastic does not compensate in real weight as the original ends.
Keep in mined that this all happens above 100km\hr,slow down and you ar ok,but if you intend to do a fast motorway trip keep your original bar ends in place.
When I hit the beach in Denmark at 01:00 the temprature dropped to 8 deg C,after 3 hr of running it got so cold that I had to stop to put on some more cloths ,stopped at the road side and kept the engine running to warm my hands at the exhaust pipe,when suddenly I saw the alarm light on low oil pressure come on.The handlebar heaters kept my hands semi warm but freezing on top of my hands, as the guards does not protect your hands well enough from the cold winds\rain.
Nice to look at but gives little protection for wind\rain.
Stopped the engine,and controled the oil level,as I tought that the engine had run out off oil,but everything was just fine,level was right at the top notch.
The reason for the alarm was that the oil was to hot and thinner after prolonged driving at high speed,why, well the original BMW sumpguard covers the oilfilter and the oil cooler but it also take away the cooling air as both units is coverd by the guard.
The engine casing was about 35-40 deg C.
Let it rest for 10 minutes and everything was fine
Recommend to use a higher viscosity oil for this kind of riding,I used the Castrol 10-40 GPS.
The day after I returned home I cleaned the bike and measured the chain and had a look at the sprockets,all like new no mesurable change in the lenght of the chain(between 10 linkes)
Final verdict
The F800 GS is up to go 1000 + miles in 24 hr, if the rider can take the strain,and you take some precausion on the hand guards and the oil,and not at least a higher wind screen.
All in all it is a brilliant bike,but for extended motorways crusing at high speed I would like to get a smaller and wider frontwheel (more rubber)as the front feels a little loose at high speed and windy condition.
What about the seat? I never tought about it, a little after sun lotion(only thing aviable in my toiletbag) in the right place can do wonders.
