To add, the obtainable max top speed for the bike's max HP output is also dependant on gearing. You'd want to gear it so the aerodymamically limited max top speed was obtained at the peak HP RPM in 6th gear.
As shown in the gearing spreadsheet link you have, the SX is geared to hit 185~186 MPH at redline in 6th gear. But I'm pretty sure it has enough RWHP to limit out aerodymamically closer to 195 MPH if it was geared ideally for top speed. Looks like Kawasaki geared the SX for a top speed of 186 to comply with the speed limiter agreements. Might mean it's not electronically speed limited if re-geared for more top end.
Are regular H2s speed limited? I see maniacs on YouTube hitting 200+ on H2s, but maybe they have reflashed the ECU or over rode the electronic limiter some other way if it has one. If H2s have one, then the SX might too, so re-gearing for more top speed would also need a limiter defeat.
But who even needs to go 186 on a "sport touring" bike.
