Not sure if anyone has put this link up before but I found this list of bike engine dyno power figures:

Interesting reading there about how fictitious most rolling road bhp figures are, with assumed transmission losses.

Interesting .
But Dyno-Jet HP numbers have been Laughable for years.
No news there.
Not exactly a large collection of engine runs though. Mostly older .
