Hmmm...interesting thread. Here's a bit of science. Front braking When bikes slow down the weight transfers to the front of the bike. That's a good thing because more weight on the front tyre means it compresses, resulting in an increased contact patch, which means more grip and so you can brake harder. However, you need to ensure there is enough weight transfer to fully compress the front suspension as otherwise you are not compressing the front tyre and so not getting that increased contact patch. That's why most experts recommend 'two stage' braking with the front. Squeeze a little at first, pause just for a moment to let the suspension compress, and then squeeze again to perform the braking. Rear braking Unless you are only using the rear brake (and there are scenarios for this, like trailing braking into a bend) then the combined use of the front brake will result in weight transfer to the front and away from the rear. This makes it much easier to lock up the rear wheel, and if you have linked ABS this can result in ABS cutting in on both wheels. But also, braking with the rear will reduce the weight transfer to the front, which reduces the compression and so the grip. The additional grip gained from the rear tyre - which is under no sort of compression and has very little 'weight' on it during braking - in no way compensates for what is lost at the front. And if you try to go for 50/50 braking - taking into account that the front brakes easily offer 4x the braking effort of the rear - then you are only applying perhaps 40% of the total braking ability of the bike and losing any benefit from increased grip through compression of the front tyre. Practical tests I recently did a machine control course where this was covered. Braking hard using both brakes just results in ABS kicking in and the bike taking longer to stop. Braking only with the front brake - using the 'two stage' approach - is much faster, especially if you brake the front to the point where you are getting the ABS kicking in again. After practising this myself I was able to consistently stop my R1200 RT (250KG bike plus whatever I weight) from 40mph in around 8 meters using front brake only. tl;dr Use only the front brake - with the 'two stage' technique - if you want to slow down fast. Use the rear back for trailing braking to slow into bends or for slow speed control of the bike.
