R1150GS...boring exhaust note...boring power delivery...boring brakes...boring paint...boring in its lack of break downs or other drama...just a boring motorcycle all together. Absolutely perfect for covering huge distances, varied terrain, inclement weather, etc.. I think they designed it to be boring. Really nice bike, but I sure would have appreciated a more exciting exhaust note or the occasional power wheelie just to keep things interesting. I guess I'm just impossible to please. I'm riding the only slightly less boring R1200GSA now.
Incidentally...a heavily modded CR500R is the least boring bike I've ever owned...pure 2 wheeled hatred and anger...it tried desperately to kill me on very outing...horrifying nightmare of a bike...never boring though...it was more scary and exciting at idle than the GS at full speed.
