Hi Goman. Got some skin in this game. Had mine 4 months now and have been able to start using it properly now that the weather is much better here in the UK. (I had a R18FE for 2 1/2 years before it so know the bikes pretty well).
Roctane IMHO does ride well, plush firm I’d call it, the larger wheels (21/19) do make a big difference to slow speed cornering (over the FE) and I haven’t yet come close to even dragging a peg. Riding position is similar, as you would expect, I really don’t have any issue with the mid pegs, I have owned a HD with forward controls in the past and I couldn’t get on with it. Guess it’s what you are used to and what you want.
Now to the elephant in my room. The heel & toe. Never used one ever before and tbh at first wasn’t that keen. It seemed awkward and I kept having to look where to put my left foot because unlike a foot peg that holds your foot in a fixed position with footboards you can float your feet all over the place. You can adjust the foot peg levers quite a bit to get your foot under there and I did try just using only the front of the gear lever (not using the heel peg) for a bit like a normal bike BUT it wasn’t really ideal and after about 250 miles I started to get more comfortable generally on the bike and felt relaxed enough to have another proper go.
I’m now over 400 miles and I’d say I use the heel & toe probably 95% of the time and actually quite like it. I’ve got some muscle memory going now and hardly ever have to look down at my left foot. It sort of suits the bike, a big cruiser. Mines booked in for 1st service in a fortnight so I’ve got just a few more miles to put on before then.
I deffo wouldn’t buy blind without a decent test ride though. IMHO the R18 isn’t an easy bike to just jump on and get the best out of it. I’ve had a few other BMW’s myself in the past (R850R, K1100LT, RnineT) but the R18 needs a different mindset and it’s why I think some people just don’t get on with them.
Gearing is very tall (60mph at 2150rpm in top) and it’s a very low revving engine so short shift it and operate the engine in the sweet spot (say 1800-3200 rpm’s) because if you try to ride it like a normal bike and rev it out or hold onto low gears with the engine spinning hard it’s will vibrate like a jack hammer. Get it right and it’s silky smooth. You’ll know what I mean if/when you ride one.
I’m very happy with mine, really like it and if there’s anything specific you want to know PM me. Hope this helps
