    Max Power

    125 hp @ 8500 rpm* ( rear tyre 115.2 hp @ 9000 rpm )
    That is only under 9% HP loss.

      Typical loss with chain and sprockets is 5-10%.

        I have two brochures for the GSXR1100g saying 130 hp.

        Is the 115.2 a dyno result? Source?

        11.4%=1-115.2/130 is still a little low.

          I am probably asking a stupid question but how does all this information help someone like me who is not a racer or that intent on performance? I ride my bike to have fun and as a means to get back and forth to work?

              I'm not a racer either but since I had a shot at a free dyno, I just wanted to evaluate the health of my motor before I invest in more work on it (secretly I want a G instead of a GL). I wanted to see if the 72 rwhp was in the ballpark of what might be expected. Jim M

                  Actually 11.4% loss is a little high.

                  Horsepower loss from shaft 11.25% average.
                  Horsepower loss from chain 6.75% average.

                    All depends on the manufacturer and how "liberal" they were in the numbers. also what the temperature, altitude, humidiity and such when the dyno is running. Also 3 different dyno can run 3 different numbers. Depends on how good the dyno is. I have had my buell dyno'd one day, went somewhere else the next and numbers were totally different. Just like ool air air makes most bikes tun better tham hot dry air.
