I have the slip ons installed and still have this flat spot around 4800 rpm... It's annoying as hell.

Anyone notice this as well?

Noticed as well, base model stock exhaust. Two things I've done to ease this: change the EBC to 2 therefore providing less engine breaking and disconnecting the exhaust butterfly valve. Both seemed to help the problem slightly although its still there. From what I've read the only people that don't have this issue have full termi and tune. Search the forum for the butterfly valve thread if you are interested in doing it, I don't have the link right now.

Have the slip ons and notice it - very annoying when trying to be smooth in lower gears

I have Tricolore (so Termi slip on) and I noticed it. Took me a bit to recognize it was happening at that exact spot. And I have EBC at 2, still there though a bit better. Terribly annoying as it is hitting right in the middle of tight mountain switchbacks, the exact time I don't need that crap. Let me know if you determin a fix. I wonder if this is something they can hit in a software upgrade. This is no minor inconvenience as if you happen to be trying to hold steady in a tight switchback and it is right on this dead spot, becomes ridiculously jerky. (And started to give me some buyer's remorse miss my RSV4 as it was very frustrating for such an expensive bike. RSV4 was VERY smooth at low speeds)

Denver Rick where are you riding? Golden Canyon? Deckers? Peak to Peak? All great rides but I have the same issues as you in the really tight stuff - hard to be smooth. And those damn bicyclists I ride with the Ducati Motorclub on meetup every once and awhile, do you ride with them?

Don't ride in that rev range. Duh!

If you've ever raced a four-banger, or even ridden one hard, you'd know that it isn't that hard. Ride first gear into the power and stay there. If you're cruising at highway speeds, you don't need the power, so who cares. It's a characteristic of the bike. Ride it or sell it.

Yeah, um, I don't go for that "it's the bike, get used to it or sell it" garbage. I ride just fine and my throttle control is just fine. And I know what it should feel like as opposed to what it does feel like. It's not like this is THAT much more powerful than my RSV4-R was. It is a good range to be in if you are used to very tight mountain turns and want to be at the low end of 2nd rpms when you enter the turn as opposed to high end of 1st to have more room to accelerate out of the turn and to reduce any jerky behavior on delicate mountain switchbacks. It is also a likely mapping/softwear issue that can be resolved through software. And I think I can go ahead and try to set my own bike up for how I want to ride it for the money I spent on it. So thank you for the completely unhelpful advice.

Only done a bit so far, but generally yes to all of the above. Golden Canyon a lot. And yes, beginning of the summer on my RSV4 a cyclist nearly got me killed. On a right blind turn, and then at last second cyclist (with of course no shoulder anyway) is struggling so hard he swerved hard into the lane right as I was feet behind him, forcing me into oncoming traffic to avoid hitting him. Luckily oncoming car saw and had time to brake enough for me to get back over safely. But could have strangled that idiot cyclist. I canot stand them on the mountain roads. I'm going to start laying thumb tacks on the shoulders.

Yup!!
Hope Austin Racing is coming along with their exhaust and map!

Look at the torque curves for ANY 1098, 1198, or 1199 and you'll find the same valley. It's more pronounced on the 1199, but they're all similar. Tune doesn't matter unless you feel like investing a huge amount of money to have MILDER cams ground to make midrange at the expense of top end.

Love it or sell it. Call it unhelpful if you like. Facts is facts.

Hint.....Don't replace it with a TZ750, it's much worse in places where it doesn't make power.
