KLR 650 with an Action Packer top box mounted on stock rear luggage rack (yeah, I'm a cheap s.o.b.). I was trained to make emergency stops by using modest amounts of rear brake (just enough to keep the bike tracking in a straight line), getting my butt up out of the saddle and back as far as possible, and smoothly/quickly applying as much front brake as possible. Moving my body of the saddle and rearward moves the center of gravity of the bike/rider back, unweighting the front wheel, which means you can apply more front brake with reduced risk of a stoppie or endo. I was out running some errands and came across an empty parking lot (strip mall under development), so I turned in for a little practice. The parking lot was big enough to get up to about 30 mph in a straight line and then hit the brakes hard. Scared the hell out of me. That top box made it nearly impossible to brake hard with any confidence. Tempted to take the damned thing off. Yes, it makes things convenient from time to time, but I'm not sure it's worth compromising on safety. Thoughts?
