As I understand it, this dyno is commonly used for bikes :http://www.dyno.com.au/dynotech/dynotech-motorcycle
If you do a bit of research, you will find that the calibration is fiddled so that the Yamaha V max reads it's specified 135 BHP. All other bikes are then measured relevant to the specified value for the V max.
If they have done that for the horsepower figures, how good are the torque measurements ?
In Australia all scientific measurements are usually related back to the standards maintained by the National Measurement Laboratories. Anything else is suspect.
