As a fellow Honda CG 125 user, I completely understand your frustration with the recent quality issues you've experienced with your bike. It's disheartening to hear about the loose back view mirrors, misfiring plug, and the wobbly wheels, especially considering Honda's reputation for reliability.
While it's disappointing that the dealership refused to replace the loose mirrors and only recommended changing the plug at just 1000 kms, it's important to recognize that these issues may not necessarily reflect a widespread decline in Honda's quality standards. Instead, it's possible that your specific bike may have encountered some manufacturing defects or issues during the assembly process.
In the case of the loose mirrors, it could be a matter of improper installation or a faulty component. Similarly, the misfiring plug at such low mileage suggests a potential issue with the spark plug itself or the engine's ignition system. As for the wobbly wheels, this could be due to imbalances in the wheel assembly or problems with the suspension system.
While it's frustrating to deal with these issues, I would recommend reaching out to Honda customer service or escalating the matter with the dealership to ensure that these issues are properly addressed. Honda has a reputation for standing behind their products, and they may be able to offer assistance or solutions to resolve these quality concerns.
In the meantime, regular maintenance and periodic inspections can help catch any potential issues early on and ensure that your CG 125 continues to perform reliably in the long run. Hang in there, and hopefully, your bike will be back to its optimal condition soon.
