Wowie +175hp at the wheel!
I wonder which model of dyno was used. Some dyno's are more generous than others.

Probably 600 dollars. I wonder if they'll release a full exhaust system to free up more weight and HP?

Peaky? It's making 60 ft/lbs of torque from around 4000 rpms. That gives it a 10,000 rpm range where it's got very useable torque.
It only looks peaky because the torque continues climbing, rather than levelling off. I guess you could call that peaky.

The S1000RR uses a 2 stage muffler. The main muffler is located at the bottom of the bike, with the catalytic converter. BMW's slip on is a straight expansion chamber style muffler with packing - there's no baffles or flow restriction to eliminate, so the Akrapovic slip-on is more or less a cosmetic change only.

Riddle me this.
What's with the dip between 5k and 6k?

Yeah. Thats what I mean, the torque is NOT uniform...
The question is what does the dyno look like on part-throttle? Does it even out or is it still pronounced?

Different left/right scales?

Nope. If you look at the torque value, you'll notice that it's in the 60-70 ft. lb. range right around 5252RPM, where horsepower is peaking at about 100.

You also need to remember that FP is trying to sell its dynos too, that is their marketing technique.

Yep, but, that just means the buyer should know...Ya gonna use it on the track or the street?
It's a track focused engine. Super short stroke to get the high RPM's, and the business done there.
The whole package might be so fun, the short comings on the street might be forgiven.
It might not hurt to just figure BMW came out swinging, to make a showing at the track, and later on will bring out another version that is street focused.

According to the BMW rep, despite the fact that it's a short stroke large bore engine, it's geared so that street take-offs shouldn't be much of a problem.

Mama says he's bona fide
The torque scale is not in lb-ft because 110 isn't reasonable for a 1000. Possibly Newton-meters (100N-m ~= 74lb-ft). Possibly just FU.
The dip in the torque curve is typical of sportbike engines. It's just more prominent in this graph because of the weird scale.

*doh*
Correct you are. The BMW S1000RR is specified to make 112Nm of torque, or 83 ft lbs at 9750RPM.
