The dyno is a tool used to quantify adjustments and make sure a bike is running at it's peak. You are looking for a baseline and then improvements. The horsepower number displayed by a dyno is :bs: because you can put the same bike on another unit and find you get a different number. Besides the fact that HP is a bullshit number. You don't ride at max HP and HP is a calculation of work done over time. The torque curve is a far more telling number. The dyno measures the torque generated and performs a mathematical calculation to plot the HP graph. What is Horsepower?
