They do show results of a dyno test but I think they missed by not starting the test reading at below 2500 rpm. Or maybe they can't and had to do the entire test in 5th gear only (not familiar how a dyno test has to be done) but there.
You can do a dyno test in any gear where you can reach the engine's red line without spinning the rollers on the dyno faster than they were designed to handle.
That chart's actually pretty telling as-is, because it's
very different than the ST's. Much more so than I expected, actually, shaped like what you'd see in a lot of V-twin cruisers. The review says it ticks over at 3,250 in 5th at 60 MPH, which is perfect for the way they have the engine tuned, leaving a little bit of the top of the torque curve available for roll-ons.
The parts fiche shows that a lot of the drivetrain is shared from the ST, including the crank, crankcase, rings, pistons transmission and final drive (same gear, different housing). I'd read that the pistons had been changed, but they're the same; the connecting rods are different, I'm guessing shorter for less compression. The top end is entirely different, with different camshafts (probably stubbier lobes), different valves and probably a different cylinder head (can't tell because it's a model-specific assembly). The throttle bodies are different, as is the ECM. (Look for MCS, the model code for the ST, vs. MJN, the model code for the CTX, in the part numbers to spot the differences.)
I also don't think the dyno results are as good as a well broken in engine, over 1000-2000 miles, would show.
Advances in manufacturing make break-in is a lot less of a factor than it used to be. Either way, I doubt you'd see a huge difference. Review bikes are rarely lent out with a goose egg on the odometer.
