Racing Motorbike Engines Power

Hi, can someone tell me what the actual power outputs are for the following racing motorcycle engines and what do they rev to?

I have seen 1000 V-Twins go to 11,500rpm, 7050 4cyclinders 15,000rpm and two strokes 4cyclinders to 12,250rpm

GP500cc V-Twin's 2-stroke
GP500cc 4 cyclinder(s) 2-stroke
SB750cc 4 Cyclinders 4-stroke
SB1000cc V-Twin's 4-stroke

It would appear to be very closely garded information and team websites don't mention much about it and are very vauge.

Less output (obviously) thsanthe v4's but expect 150-160HP

GP500cc 4 cyclinder(s) 2-stroke
The belief is that they are producing about 185-190 HP


SB750cc 4 Cyclinders 4-stroke
&
SB1000cc V-Twin's 4-stroke
I'd have thought the 150+ mark was about right, but have no real figures....

Don't you think the SBK's are in the 185-190 HP range as well?
They're quite heavy but still very fast. Maybe desmo knows some accurate figures for the Duc?

Dino that is right.

The GP four cylinder 500's have the same power output as the 1000cc twins and 750cc fours in the superbike championship - but they weight far less. About 50 kgs less in fact.
