My 85 v-max was very uncomfortable. I put a Corbin seat on and it helped a little. Corbin is so hard.
It only weighted 650lb and the power (142hp at the crank) was effortless. But it loved the highway on long cruses, as does the B.
If I could have had a comfortable seat, I never would have got rid of it.
The internet says the 2013 B Has 117hp and 125 ft lbs torque.
Anytime you have more torque that hp, you have a runner!
