I hit a financial pot hole and had to sell my two bikes back then(FJR1300 and Triumph Speed Four) to get by, but it left me enough money to snag an ex demo 2012 ER6n in good condition, had it a year with dauly use, not a single fault.
I hated it at first, couldn't put my finger on why but I've finally grown to love it, as you said, at first it felt a bit gutless but I think I was being too soft with it, never had a parallel twin bike before.
Now i'm looking to improve on it and repaint it, love the bike to bits!
I use it for my daily commute to work, its my only transport, bike felt like it handled wierdly to me at first, but I was spoiled by my previous Triumphs handling, took a while to get used to the ER6n for me.
Had it a year now and love it, its got plenty of usable power, I'm a sensible/safe rider but have had the odd "fuck the speed limit" moment when nobody is about etc and had 110mph out of it but I live in windy rainy england, but it didn't struggle to get to that speed either, could prob get the wheel up easy enough on it.
Traffic, it handles great, the bike is quite narrow, in the UK you get a lot of cunts try to move over and stop you filtering, but this thing is so narrow that you can still squeeze by and laugh to yourself.
Only thing i'd fault is the suspension, could be better, but again, I was spoiled by the Speed Four I had which had some very fancy suspension on it.
Good bikes, sensible, but with enough power to have some fun, have had a few "two up" runs with a work colleague and it handled them fine too.
Only pic I have of mine, taken after I just got back from collecting it.
