I am new to the site but have lived in Wein for 2 years , speak Deutsch,and am a motorad(motorcycle) enthusiast...living -working in Europe many,many years. I will ( if you read Barcelona) only commment on biking in Austria.It is perhaps the cleanest nation ,with recycling and a Germanic "alles in ordinung" mentality that although is prototypically anal..none the less appreciated as a "Sound of Music"vista.please read Barcelona "motos" or you will miss the jist of my point of view.Visit the Wiennerwald(Vienna woods) just out side the city up by the old historic church in May for spring wine and a great view at 600m.Next, if you are a real rider the boys and girls met every weekend near Baden...call for the H-D American bar in the !st district near Riemergasse St.the owners will tell you where to go and who to party with.In general...the country side is " beyond imagination"green, nature, clean, cheaper,stay in guest hauses, a must see is Grossglockner hoch alpine strasse...stay in Zell am Zee, Bruch,  or come from Saltzburg SW to the "High Towers" natural park area....be prepared to go to heaven...only for expeienced riders who can contoll themselves...I apparently can not having crash twice in sudden summer ice storm at 12,000 ft....I am not dead yet and bikes are made to be repaired.Visit the Salzburglanderegion of lakes and bathes(Bad)Short rental are available with a m/c license.Eidelweisse Tours are prmo but cost,HQ is Vienna.just call.This could be a 10 page account of when and where to go but I am assuming the average reader is on a shorter budget/time span than mine was...so just read the Barcelona  moto section and extrapilate  and pick up pointers.
