The braking system is equally impressive, featuring a single 300 mm disc brake at the front and a responsive drum brake at the rear for reliable stopping power. With a fuel capacity of 14 liters, the GPR 125 allows for extended rides without the frequent need for refueling, making it an ideal companion for both daily commutes and weekend adventures. **

- Small Fuel Tank: The 14-liter tank, while sufficient for urban riding, may require more frequent stops on longer journeys compared to larger sportbikes.
