Congrats on your new/used ride. I am impressed on how sharp you are (probably because I admire your thought process). As my GS1100 was hitting 100K (still in excellent running condition), I began to look for a replacement stead. I tried out a brand new Yamaha Tenere (former Yamaha RD350 and XS1100 owner/ Yamaha cool aid drinker). After an extensive test ride I wa s shocked! The Yamaha isn't in the same league as BMW's 18 year old design, the GS1100 . And forget about any Tenere comparison to the GS1200. My issue was solved by buying a BMW 98 GS1100 with 6,000 miles.
As for your plan to get training, RawHyde is an outstanding experience in every way. Fantastic value, with techniques that greatly enhanced my ability to take the big pig on an adventure.
