Fat Boy comes with a single 300mm disc brake at the front with a 4-piston caliper while the rear single disc brake is operated by a 2-piston caliper. Given the mass of the motorcycle, it would be nice to have a stronger braking package with a dual disc setup up front. ABS remains standard.
Fat Boy comes with an 18.9 litres of fuel tank capacity which roughly translates to a range of around 280 km in one full tank. Not bad for a big, heavy and a powerful cruiser.
