Yes, this is exactly what I am talking about.Having had my ‘21 S1KRR for two weeks now I certainly agree with the Nissin v Brembo “bite”. Had Brembo on my Ducati and as am I’m learning the new BMW with Nissins, I’ve had one “puckering” moment where I thought I was applying typical hand force for breaking and made the nose dip considerably. This was during my first weekend with the bike. Probably also my fault in riding some twisties I’d never ridden before so soon and coming in too hot in a right-hand switchback. Haven’t done it again but definitely is more top of mind when braking on the BMW.
You will get used to it, its all lever control, but at the same time in a panicking situation the brembo/hayes are probably going to keep you out of trouble if you don't know what you are doing. If you grab a handful of the Nissins you are going to get more trouble than you ask for.
Most guys will probably opt for a brake pad that goes the opposite way of the brembo's, to give the nissins less bite.
I am definitely interested in hearing more input on these from more riders.
