Because I cleaned my bike. 
I put more miles on the F800 today in order to meet the "deadline" which I imposed on myself by booking my first 600 mile service due in a couple of weeks. Until these initial services are out of the way, I always feel very constrained on a new bike. 600 miles is too short a distance to go for a decent tour - besides which the "running-in" limitations on revs etc. means that sustained high speed cruising to some distant destination is no-no, but it''s quite a long way for just cruising the local lanes. I compromised today by a lengthy exploration of lots of country lanes with nice twisties and hills followed by a reasonably quick return home along main roads. The net result is some 300 miles on the clock and a very dirty bike that needed a very good wash.
The sun was shining and it was very warm when I started but by the time I had finished cleaning the bike, it was raining and cold. I used sDoc 100 to clean it - first time I have tried it but it seems to get a good press so I hope it does what it''s supposed to and protects the bike with a corrosion inhibitor as well as helping to clean it.
My verdict on the bike so far is that it is simply brilliant. I had been reading various pundits on different forums say that it was too focussed on off-roading to be a good road bike, mainly owing to the 21 inch front wheel. What a load of cobblers! This bike turns as fast as I shall need it to. The wide bars, the light weight etc make it very flickable and the super engine certainly make it a capable tourer too. I am very eager to use the full rev range - currently restricted to 5,000 rpm - it will make it an exciting bike to ride quite fast and to cruise comfortably at a decent mile eating speed.

The seat is quite a lot higher than the Goldwing and even familiar roads revealed new secrets to me today as I was able to see over lots of hedges that previously obscured interesting stuff - often it was fabulous houses in the middle of nowhere with enough land to build a couple of golf course and motocross circuits. Sometimes just pretty countryside.
