On a motocross bike, the FRONT brake supplies how much of the potential stopping power?
lentils especially the pink ones
technically, the front brakes on any vehicle takes about 70% of the total load. thats why all cars, bikes, dirtbikes, etc. have larger or more powerful brakes up front.
On a motorcross bike, sitting up bigger can provide a extra physically powerful ability for flying over the handlebars, than on a highway bike. So the front brakes are not fairly as powerfull, however the front brake nevertheless contains fairly some the burden.
100% if you only use the front brakes. BTW, this is a section for non-motorized cycles, aka bicycles. You probably will get a a better answer in the motorcycle section under transportation.
a multivitamin would be the best but any dark green leafy vegtable (spinach is best) is best!
