At the heart of the AJS NAC12 lies a robust 124cc twin-cylinder, four-stroke engine that churns out an impressive 11.39 horsepower at a brisk 10,500 RPM. This power, paired with a five-speed gearbox and precise chain final drive, delivers a responsive throttle and smooth acceleration that makes navigating through city traffic or winding roads an absolute joy.

Beyond its impressive performance, the AJS NAC12 125 MK2 is equipped with notable features that enhance the riding experience. The motorcycle comes with an electric starter for effortless ignition, while its suspension setup—featuring a telescopic fork at the front and twin reservoir shocks at the rear—ensures a smooth ride over various terrains. The dual front discs and single rear disc brakes provide reliable stopping power, instilling confidence in riders. Available in striking color options of red, white, and black, the NAC12 is not only a performer but also a head-turner on the road. Furthermore, with a generous 18-liter fuel tank, this bike is ready for longer rides without frequent refueling stops. **
