Yes, good point. Another one to consider, maybe, is the dyno device itself. The very same bike objectively measured on two different kinds or brands of dyno can show up a rear-wheel HP reading variance of up to 10 to 15% (Source: MotorSport Schweiz) . I candidly suspect that most stores selling dyno readings dial-in a 10% extra to flatter the average screamin' seagull watcher's ego. Conversely, I seriously suspect that "official" dyno readings (such as the one Tracker refers to, perhaps) are deliberatly tweaked down to show the most conservative readings.
Why? To avoid motorcycle mags or customers eventually bitchin' about their mount delivering fewer ponies than advertised... to give OEM's a chance to incrementally shine with their own "off-road" power accessories... to placate road homologation bureaucrats (at least in Europe) and insurance companies...
And then, there is that new, trend, at least in Europe and in Japan, and that is the forced (or rammed) air effect on power when measured on the road or track, as opposed to a -STATIC- dyno. The 2006 Kawa Z10 would thus gain 10 to 15 ponies at full speed, just by virtue of that speed-boosted oxygen intake.
Hey, I don't mean to louse up all those spontaneous rear-wheel Rocket III output (vaguely competing?) reports. Mine included. Just to suggest that universal " rocket science" (pardon me, Toystoretom) it ain't.
Let's keep some Rocket romance up, please
