Just read the Air Cooled 1200GS (2004 - 2012) sold 180,000 according to BMW, an average of around £20k per year over the nine year run.
I reckon 10:1 ration to Super Tenere's may be fairly accurate, can't see the new one doing as well just due to sheer number of bike now in this segment, in 2004 at the height of Ewan McBoredme fever there wa sonly a few bikes in this segment, now there are a dozen or so all jostling for position, they caught the crest of a wave and rode it perfectly.
Plus now many of the new sales will be to existing owners, the flood of used GS models into the market with the die hard lining up for this new model will supress sales as those who have not yet migrated from their sportsbikes have a vast choice of cheap used GS' to choose from, as well as they dozen or so other bikes.
What is starting to change in the UK is these bikes do get taken far more seriously by the press these days, I remember reviews of Africa Twins and XTZ750's etc back in their days were always utter pistakes, the reviewers would cane them flat out and start moaning about these ridiculous bikes that were slower than an FZR400RR and produced crap lap times. I still think the UK Journo's don't get the long term ownership thing, but they are starting to appreciate that a bike that "only" does 130mph and has less than 150BHP can be fun to ride, and I think this market will start to grow further.
I am also seeing mates testing these bikes now, some will trade in, and I know others who instead of trading there 3-4 year old sportsbike for the latest model are keeping hold of it and looking to get an adventure bike as a second bike, and we all know which one will end up sat in the garage 90% of the time :exclaim:
