G'day from Missouri, whatever that means.
I've only put about 2,000 miles on my new 2012 R3r and I enjoy it.
Having owned 79 bikes, of which were 5 BMW's, Many touring bikes, ****** rockets, adventure bikes, dualsports, desert and track bikes, I find myself now with the new Triumph and a 2012 Suzuki Burgman 650 Executive, both of which are really fun to ride, quickly or sedately.
When ridden in the "smell the roses" mode, through the beautiful country roads of the Ozarks, I get 45 mpg, because the big baby is just barely into it's 165 ft lbs torque curve, that swells at surprisingly low rpm's. Herein lies the problem with LOTS of torque, horsepower and it's effect on tires: They just don't last as long!
Other big bikes don't do very well with tires, like my Past Honda VTX 1800 or my past Suzuki 1800cc cruiser that also had a huge 240 series tire on the rear. The torque on take off on these bikes, even if done with little throttle still has a tendency to "shred" rubber.
My past 1500 and 1800 Goldwings, BMW K1200LTC and my Electra Glide would normally go about 14 thousand on Premium OEM Dunlop touring tires.
You will probably enjoy the rush of your first flirtation with the throttle and high gear passing, from ANY speed will almost assuredly beat most anything you or I have ever ridden.
Both your BMW and the Triumph brand has few dealers in certain parts of the U.S. as you probably know so choose accordingly.
