The difference people are feeling is in the lower rpm range where the 107 starts with more. If you notice in the 2.5 range the HP is maybe 2-3 more on the 107, but the torque is sitting around say 5-7 more. Is that enough to feel on the butt dyno? Maybe, maybe not, but if you are expecting more out of it then I would say you are finding it. Certainly there is some psychological power there as well.

I find it hard to believe the 2 engines are running that close on dyno runs, the actual real world difference is pretty noticeable from riding both back to back. And so far everyone i know that has taken a test ride felt the same. This is not a post doubting FM its just a post that its hard to imagine they run that close on numbers.

Surprised that the 4 valve head doesn't breathe any better in the upper RPM register.
I figured it would/should show supremacy by 3600-3800 RPM at the latest.
Guess I'll keep my lowly 103HO.

New Stock 107 versus new stock 103.
Presented as the results of a brand new stock 107 versus a new stock 103. I got tnhis at the dealer and really don't know how to read it but it seems to be impressive to those that do.

Yeah I don't think anyone is riding Harleys cause they're cheap. And the added torque of the M8 is only the beginning on how this bike is better than the TC.
I knew when I rode one two days after release I wanted one. I wanted one bad. But I also new that dealers would be marking down twin cams to move them. The thought of a 110" TC for less than my M8 cost me was tempting for a minute or two. But there would be much more that I'd be giving up. Much, much smoother. Much better handling. I'm glad I didn't worry about the added expense.

Urban.... has a dyno, they didn't do a great job of tuning my scoot a couple of years ago.
