It also features an EX300ADF ignition that provides a significant improvement from the 250R. This model series sold well in North America, Asia, Europe, and Australia alongside the 250R. But some stores have replaced the old 250R with the new Ninja 300.

A few customers claimed that the 2013 Kawasaki Ninja 300 engine had an internal fault that could stall the engine. An ECU installation solved this small problem.

The 2014 Kawasaki Ninja 300 is similar to its predecessor, but the rare issues with the 2013 series were resolved. Also, the company added other colors that customers can choose from. The 2015 Kawasaki Ninja 300 came along with no significant differences from the 2014 model.

In 2018, the Ninja 400 was introduced to the market, and the Ninja 300 has a new replacement. However, motorcycle riders continue to buy the 300 as it is cheaper but still reliable.
