Yes it is. I've had the R1200RS version since May of 2016 and love it. The R1250RS has several tweeks to improve it beyond the more power and torque. It is significantly lower C of G and weighs substantially less than an RT. I've added 1 bar risers and foot peg lowering kit to help unfold my 73 year old body. I also put on a little wider, not higher, wind screen to help with rain management.
The only thing that would be better would be a version that would be 50-75 lbs lighter. I'd be more than willing to accept 90-100hp engine but would want to keep the excellent suspension and features.
