Well here are the results from the same dyno, round about same time of day and temp. Base run was stock bike and next run was the bike with the 70mm termis fitted ,air filter and ecu, total gain is about 6 bhp at the rear wheel. I would really like to know where Ducatis claim of 160bhp comes from. Also where the 8% increase in power is, at my reckoning it is only 4%. Feul slightly lean, only slightly, with some adjustments possible extra 2hp may be found. If you dont believe these figures do it for yourself but make sure you go to a reputable dyno that doesnt give inflated figures.

Reference Ducati's claim of 160HP, manufacturer's claims are always reported as HP measured at the crankshaft. (although most seem to be measured at the brochure) If you take the aproximate 15% drivetrain loss off of that figure, it comes out to 136 rear wheel HP.

Another example, when the ZX-10 first came out, the factory claimed 184 HP. Less 15% drivetrain loss, that comes to 153 rear wheel HP, which is about what most buyers reported from their dyno runs.

It's all relative. Forget it and enjoy your bike.
