I've been on my E1 for almost two years, and never once wished I had more torque or acceleration. It's more than adequate for real world conditions, which for me is commuting (including freeway) and occasional runs through the Southern Marin twisties. I do leave it in sport mode.
But there's no denying the torque difference between the E1 and the R. It's big. If I was buying today at these fire sale prices, it would be hard for me to pass up the R. We're motorcyclists, that means we want more power, not less!
At 165 lbs I'm probably right in the wheelhouse for how factory suspensions are set up. Someone who weighed more or less might find more value in fully adjustable suspension. But I don't really know what I'm talking about, more just repeating the common wisdom on this topic.
