I bet if you practice some single track on the Strom, it will make your XRR seem lighter. 
I bet it would.
It may not see any single but the forest roads and some easy trails are game. The strom doesnt feel like it would be too much of a hand full. Its tall but I can flat foot both side with some room to go. The power seems manageable.

My cruiser is turning almost 4 grand at 75mph, just felt like i was flogging it on a 350 mile interstate run, it only has 3 gal of usable fuel which gave me a range of 100-120 miles.

Highway pegs, didnt help.. sheep skin, didnt help..
