I'm curious as to how other sportbike riders handle it... the last 1/4 mile to my house is a bit curvy and a mix of dirt and gravel, so is my driveway. Reducing speed and riding straight up has kept me out of trouble but last year my dog decided to play "suicide rabbit" right in front of me on my driveway. To avoid the dog I grabbed full front brake which caused me to go down real quick. After repairing the bike I've been experimenting how I could have done it better and here's what I've found...
Full front brake causes a front tire skid with ineffectual steering and an unpredictable direction of travel.
Full rear brake causes a rear tire skid with a more predictable direction of travel however the ass end usually comes around.
Applying heavier rear brake action and limited front brake seemed to be the best to stop or control the bike in a gravel section while minimizing the angle of the bike.
Suggestions and techniques are welcome because even in summer I've seen gravel wash onto the road from the high side of curves and driveways.
