During the break-in period of a new motorcycle, it is common for the manufacturer to recommend certain guidelines for engine RPM and gear shifting. These guidelines are typically designed to ensure proper seating and mating of engine components and promote optimal engine performance and longevity.
In the case of your new Gixxer 250, the recommended break-in guidelines might be emphasizing lower RPMs and more frequent gear shifting at lower speeds. This could be why you feel the need to shift up to higher gears at lower speeds, even though the engine revs loud.
It's essential to follow the manufacturer's recommended break-in guidelines during the initial period of owning your motorcycle to allow the engine components to properly wear in and establish optimal performance. This period typically ranges from a few hundred to a few thousand kilometers, depending on the manufacturer.
If you find the gear shifting pattern uncomfortable or feel that it is too frequent, you can try adjusting your riding style slightly by letting the RPMs build a bit higher before shifting up. This can help you stay within the recommended RPM range while still maintaining a comfortable riding experience. However, it's crucial to strike a balance and not exceed the recommended RPM limits during the break-in period.
If you have concerns or specific questions about the break-in process or your Gixxer 250's performance, it's always best to consult the owner's manual or reach out to a certified service technician from the manufacturer or an authorized service center. They can provide you with accurate information and address any issues or concerns you may have.
