Agreed.To me engine brake is amount of deceleration when throttle is closed, I didn’t think there is any engine brake after throttle is opened 1%
An easy test is to accelerate to a given speed; e.g., 60 MPH and pull in the clutch. Note the deceleration. Now do the same without touching the clutch lever and add throttle until the deceleration is the same. It takes just the tiniest touch of fuel to overcome engine braking.
A bit of useful data would be to know the difference in fueling between the S1000RR's engine braking in slick mode v. all other modes.
