Ha it keeps the chain tight and eliminates driveline lash. Best practiced on a scooter in the neighborhood. Where the speed limit of 25-35mph can be used turn after turn. But also the easiest way to loose a tailgater on any bike going into a corner. But even on a straight away applying the rear brake with the throttle eliminates drive line lash. I tend to ride with a locked throttle hand the older I get. And revert back to the Kieth Code videos on how to open the throttle when the time is right. Also no velocity drops in the intake charge of the motor playing throttle games for a minor speed change. Upsetting the chassis never works. And driveline lash and a velocity drop equalling poor mixing will do it every time. Also hammering the front brake can change rake trail to throw the bike on an edge then to follow with a wide open after the apex. Comes very natural riding a super moto, a scooter and a sportbike in the same day.
