Re: Disc braking in Bike
It will not affect mileage but will certainly affect your longevity by making you live longer.
Have you ever seen Dara Singh in old movies trying to stop a Truck with both his hands? Would the truck have stopped as easily if he were applying only one hand to stop it? No sir, it wouldn't. Similarly, a dual disc brake setup would make a motorcycle stop quicker than a single disc setup which, in an emergency braking situation, could mean the difference between life and death.
More braking force is always 'suggestible' on any road, be it Indian or African, or Pakistani, or American.
Understood? Now go get that motorcycle with 'dual' disc.
