The same bike on the same dyno but on a different day would generally read different. Air temp and pressure make a difference along with tyre pressure and i suspect, even how tightly the bike has been strapped down. A dyno tune can only show differences of before and after changes on that dyno on that day. It'd be nice to see the 140bhp trace to see where else the akra gave gains cos 5 odd horses at peak and no more torque isn't really a good showing from arguably the best exhaust manufacturer.
Corrected for you... I believe Ducati always measured at the rear wheel until around 2004/05 when they changed inline with the rest of the industry. This is why there was a large power increase from the equivalent gen 1 to gen 2 999's I believe.
