Other Bikes » why less power for the U.S. market?

In Issue 1 of 2020, Cycle World magazine reviews the new 2021 Honda CBR1000RR-R (enough "R's" for you?). In the article it is stated that the EU model has a claimed 214 HP at 14,500 rpm. However, the version to be imported into the U.S. market will only have 186 HP at 12,000 rpm, due to "U.S. regulations". Does anyone have any thoughts why U.S. regulations could neuter the bike to that extent? I have seen recently that some sport bikes imported in the U.S. have less horsepower than their EU versions, but not to that extent. I wonder why?

Wikipedia: "A gentlemen's agreement was made among the major motorcycle manufacturers to limit the speed of their machines to 300 km/h (186 mph), starting with 2000 models."

I wonder if the journalist is confusing mph with bhp?

Just a thought.

Maybe the 3rd R stands for reduced.

Agree - not clear to what regulations the press release refers..., unless it's an insurance thing.

Strikes me that an engine that produces 186 HP at 12,000 should produce close to 215 HP at 14,500.

The numbers don't explain the 205 horsepower 2020 S1000RR I had the chance to ride on the track a few weeks ago.

ROW?

I think I got it. 186-HP at 12000-RPM is a torque than 215-HP at 14,500-RPM. The "American spec" model just rated the engine at the max. torque condition instead of redline.
