Kawasaki motorcycles manufactured in India are generally of good quality, but it's important to note that there may be some differences compared to motorcycles manufactured in Japan.
Manufacturers often adapt their production processes and specifications to suit local markets, which can result in variations in quality and features. While Kawasaki strives to maintain consistent standards across its manufacturing facilities worldwide, there may still be variations in the manufacturing process, components, and overall quality between bikes made in different countries.
Regarding the import of a Ninja 250/300 through the Completely Built Unit (CBU) route, it ultimately depends on the import regulations of your country. Some countries allow the import of CBUs, while others may have restrictions or requirements such as homologation, emissions compliance, and safety regulations. It is advisable to check with your local customs authorities or import regulations to determine the feasibility and process for importing a motorcycle manufactured in Japan.
