There are a couple of other changes that interest me. Per Bennie's post:

"...
Blue M Calipers
New side fairing
210 HP - K66 cylinder head, intake and airbox - +3 HP @ 13750 rpm (+250 rpm)"
Plus changes to wheelbase and steering head angle. The bike is very nimble now .. are these changes to increase this or make more stable?

The cylinder head (and other?) changes to the motor are of interest. What was the goal / what are the benefits over current gen?

More stable. Longer wheel base like the M.

More power, more air flow.

Wonder if K67 TFT can be upgraded to new features.
I am working on it. I have a 2023 ECU on order already. Once I get it I can see how the hardware numbers match up in programming. I expect it to work. The S1000 TFT can be changed to a M1000 so as long as the hardware numbers are the same for the 2023, then it will work.

So the main difference is the slide control electronics, and winglets? Trying to understand the difference
Check the PDF. There's a lot of refinement and inheritance.

Maybe I’ll replace my 2022 to the newer model but not anytime soon. Love the M package color even though the red looks amazing. BMW just want you to buy as everyone else and if we will follow trends then we will buy every year!! It sucks but that’s the way it is

Europe Press release is here with the specs for it.


Clearly not for USA market in this configuration, but its all in the ECU. Still at 210HP is crank measured for BMW specs. Even my tune is 204HP at the rear tire which is 216HP Crank.. Taking the EURO 2023 tune should not yield any more, but, the air box could be a big factor in the coming months. It just turned dyno weather here in Texas. I have had other projects the last 3 weeks so hopefully I will finally take the air box from my M1000 and do some testing with it and the 2023 Euro tune.

EURO press release---- Advanced 4-cylinder engine that sets a new benchmark in terms of performance, torque and rideability.
The new RR features a 4-cylinder in-line engine based on the power unit of the current S 1000 RR. Peak power is now 154 kW (210 hp) at 13,750 rpm (does not apply to US machines), 2 kW (3 hp) more than the previous model. The maximum torque of 113 Nm is generated at 11,000 rpm. In spite of an increase in peak output, the usable engine speed range of the new RR is now significantly broader and more fulsome. The maximum engine speed is 14,600 rpm.

Not saying you are wrong, but numbers still don't add up to 205. 154 kw is 209.4 SEA hp and US spec shows 205 hp @omasou
Horsepower is a measurement of the engine's ability to perform work.

One SAE hp is the ability to lift 33,000 lbs one foot in one minute.
One DIN hp (DIN stands for “Deutsche Industrie Normen” or “German Industrial Standard”) is the ability to lift 450000 kg one cm in one minute.

For the same power the SAE measurement is thus 98.629% of the metric DIN measurement.

154 kW * 1.36 = 210 (209.44) DIN HP * 98.629 = 207 (206.57) SAE HP

NOTE: Unless they detuned the engine :confused:. The US web site and press release have a typo 2023 S1000RR is 207 (not 205) SAE HP.

It could be, but it's hard to believe that BWM would publish lower HP in multiple places due to a typo. Manufactures inflate HP numbers, so there is something else going on with US models. Not that it matters, but I am just curious.
