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. |

GP500cc V-Twin's 2-stroke
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. |
