Of course all bikes produce peak power at higher rpms, but what I meant to say about the 899 is that it revs higher than bikes I've owned. I haven't had a 4 cylinder bike in many years. Most of what I've had are twins cylinders and single cylinders which are happy at about 6,000 RPM. The 899 is different from those in that in doesn't seem to wake up until you take it above 8,000 RPM. I took it no higher than 10,000 RPM but it probably could go higher. Max on the gauge was 12,000 RPM with no redline indicated. Hope that helps.
