Note that these numbers were measured at the rear wheel and that we can safely assume that Triumph estimated a loss of about 11 hp at the CRANK, therefore we can assume that the loss measured using a dyno would not make the max hp fall under 80 hp.
Note that the max torque advantage of the SV is only slightly less than 7 lbs/ft although the torque spread is nicer (flatter). You should keep in mind that retuning the TT600 engine will make it lose in max hp but will favor a flatter (and possibly beefier) torque curve.
One very nice thing about the ECUs in the Triumphs is that you can modify the fuel maps using your computer (software and a cable are required). Don't put FI down, it can be pretty good thing more often than not.
