I own both bikes. The FZ8 is drastically faster, everywhere. Even pulls cleaner and quicker from 2,000 rpm. Pineapples and mangoes. I guess I should elaborate a bit; the bikes are posting pretty similar 1/4 mile and roll-on times, but those are done on a straight piece of road under controlled conditions. It's obvious that the FZ8 makes a lot more raw HP, 96 compared to 84 for the CB1100, but the CB does make more torque, especially at low RPM. However, that just doesn't come into play in an outright honk to rip up to speed. The CB1100, weighing 80 more pounds, has a huge weight disadvantage. HP/weight is 1:4.86 for the Yamaha and 1:6.45 for the Honda but that's not the whole story. I've posted myself here about how quick the CB can be if one keeps the tach between 6-8K, but obviously you're already breaking most speed limits just in second gear there. The FZ8 is just getting started when the CB is hitting the rev limiter. The FZ8 makes over 80 HP at 8000 RPM and just keeps swinging until past 11K. It's not so much even about the HP though as the willingness of the FZ8's engine to rev quickly and freely, and for the bike itself to accelerate easily. All the rotating mass in the FZ8's engine is much lighter than in the CB's, and its wheels are lighter. Combine that with the 80 pound weight difference and you have a bike, in the FZ8, that accelerates very briskly and easily. I would never have even thought to compare the two bikes in the same sentence but since its been done, I'm just going on the record so as to not have anyone come away thinking a CB1100 will give the FZ8 any kind of run for its money in the real world. It won't.
Uh, mine makes 93HP.
