I currently have an 09GS and would like, and appreciate a 2010/11, because of its improved engine. Also, I'm waiting to see what BMW does with the new, totally revised, "possible" water cooled, 1250/1300 etc. GS/GSA. However, my 09 is "so good", "so competent", that its virtually erased that need/urge to look for new.
Also, (one reporters opinion) over 30 years the GS/GSA has been properly improved/refined, to a point that "some" still prefer their 1100/1150's.
In the recent Fast Bike comparo between the new/latest Multistrada 1200S, Yamaha XT1200Z Super Tenere and 2011 GSA (which, I believe has "essentially" been around since 2005, but has the HP-2 derived heads), it came out on top. At the end of the article, they quote, "More telling still is that if you put the 09GS in the test instead, the outcome would have been the same".
