Went back to the dyno today...

[the Ferret]

The 83 CB 1100F put out a reported 108 hp out of an 1062cc mill. That's a far cry from 140

Crank or wheel?

My bike 'uncorrected' (true hp) put down a little over 106 so depending on what a person believes for drivetrain loss-

10% loss would be 118 crank.

15% loss would be 125 crank.

I assume it was rated at the crank back in 83 and not dyno's. Maybe I can find a dyno chart for one.

Well couldn't find a dyno chart but found other sites listing the hp at 99 and 104.

Found these figures for the mighty 6 cylinder CBX which was faster than the CB 1100F

105 hp (78 kW)@ 9,000 rpm (claimed)
1978-1980 100–103 hp (75–77 kW) (claimed)
1981-1982 98 hp (73 kW) (rear wheel)

the V65 V4 Honda Sabre put out 121 hp (I imagine also measured at the crank)

There were no 140 HP inline 4's from Honda
