I notice on my '16 that there is a noticeable flat spot at around 4,000 rpm, and I have to throttle or drop a gear to get past it. My old BMW R65 had one at exactly 3,600 rpm. So it may be that on the '19, that flat spot moved north to a higher rpm?

My 2014X had a spot at 4800 rpm that was rough-this is different it was just a lack of power that I thought the bike should have-I'm sure with more miles and cooler weather reg gas will be fine-but for now I'm enjoying how the bike is running with mid grade
It's not a big motorcycle just a groovy little motorbike

My advice when it comes to fuel is to use the least expensive available that does not produce knocking. This was especially true back when I was riding BMW bikes with their manufacturers requirement for premium fuel. I ran mid-grade for the 4 years I rode Beemers.
Iíll think of something later

Iím the opposite. I buy the best gas I can.  Itís a small amount and as ambient temp rises it makes a difference

I think it was mentioned before, but even the most basic fuel in the UK is actually 95 octane.

Owners manual says 86 octane or better, so I buy regular unleaded and haven't had an issue yet.
