Horsepower = (Torque * RPM) /5252 so the horsepower figure is more easily skewed by the addition of RPM i.e it is way easier to add 1,000 rpm to a motor than 1,000ft/lb of torque. Give me a 100ft/lb of torque over a 1,000 rpm any day.
Not only that at what point is the torque delivered.
The X11 engine is a retuned Blackbird engine.
Look at the specs.
Blackbird-11500 RPM, 112n/m of torque, 165 HP
X11-10,500 RPM, 116n/m of torque, 130 HP
The key difference is the torque delivery. The torque on the Blackbird only really starts to kick in at around 6,000 and pulls to 10,500 rpm.
On the X11 it kicks in at 3,000k rpm and pulls to 9,500 rpm.
Seat of the pants, the X11 will out accellerate the Blackbird and have no problem taking it in a roll on. The Blackbird will out top end the X11, but who wants to over 250kmh on a naked bike anyway?
So just because the spec sheet says one has more horsepower or one has more torque don't mean it is going to go quicker. And we haven't even started on handling.
