FAQs
Q1: Is this plug specific to the CBR250R, or does it fit other Honda models too?
A1: This part number is listed specifically for the CBR250R rather than shared across Honda's broader lineup the way some of our other Honda-fit plugs are.
Q2: Is genuine NGK still worth it on an older, discontinued bike like this?
A2: Yes, an iridium upgrade tends to be most noticeable on higher-mileage engines, since a finer, more consistent spark can smooth out wear-related rough idling and starting.
