For me, it sounds like the SR/F would have too much power.
That was kind of my thought when riding it as well. It's hellafun, but I kept asking myself, where would I use this much torque?
Of course, you can dial it back, but why buy it in the first place is you're not planning on using it. If I lived near a track, it would be a blast, but I don't. On the street, that was a ton of power that would only serve to get me in trouble.
I'm sure if the SR/F I rode had the rider assist tech enabled, it would have felt more subtle. Not bringing up the front tire or sliding around corners, but still, its a lot of torque. Wish I could trade some of that 140 ft lbs. of torque for more highway range.
To me the FX and DS have plenty of usable torque. I'm not sure I'd even need a DSR for my uses.
I guess it all comes back to range for me. I've got a few 800-1000 mile trips coming up in the next few weeks. I'd love to do it on an electric bike, but it just doesn't seem feasible at this point.
