Keeping the crotch away from the tank before entering the corners can be a strenuous exercise for our legs. The body tends to slid towards the tank all the time. Sure tightening the legs around the tank when breaking helps, but I was wondering if there is any gear designed for correct body position. All sport bike seats I've tried are too long and "slippery", probably to compromise between track and street riding and to accomodate different rider builds/height. I remember one of the coaches saying that pro riders use modified tank shapes to fit their body type.
Is there any gear to help keep the correct seat position? All seat customizations I've seen are mainly for comfort.
