Which begs the question why?

Your suspension works best at its mid point. But entering a turn hard on the brakes transfers all the weight up front, which changes your steering geometry (making it quicker) as you release the brakes your front suspension extends, slowing down the geometry. As you roll on the throttle exiting the corner, your suspension, front and rear, extends still further, further slowing down the geometry.

All this fork movement really unsettles the bike. and depending on the situation, leaves the suspension unable to cope properly with road irregularities or corrections.
The problem with fork movement isn't that it moves it's when it "pogo's" you want to get your forks compressed under braking which helps the bike turn in and through turn in so you don't suddenly unweight the front coming off the brakes and have them smoothly extend as you get on the gas and come out of the corner. The goal is have them go down one time and come up one time smoothly each corner, and not go up down up down etc

By using the brakes AND throttle at the same time, it's possible to keep the suspension in the sweet sport of suspension travel greatly stabilizing the bike all through out a turn.
That I agree with but it has nothing to do with only using 1" of travel past sag.

Side benefit is the potentially increased ground clearance because your suspension isn't effectively collapsed when you need it the most.
Well, nothing but spring rate determines where you end up in your travel for a steady state cornering load. To use less travel you either get stiffer springs or you don't brake / turn as hard.

If I tried to ride around only using 1" of travel I'd be _very_ slow.

Rossi hard on the brakes


Jorge mid-corner


Casey Stoner accelerating out of a corner (gives you a good idea of total travel available to the rider



So could you explain why you where trying to use such a small amount of travel? Or what the actual drill is you where doing?

Also to the guy who wasn't sure about the suspension extending under acceleration, look at the distance between the bottom of the tire back tire and the bottom of the bellypan between the mid-corner and the corner exit shot. The bike leaving the corner is doing a wheelie so it has 100% load transfer to the back wheel and the suspension is almost if not fully topped out.
