Model: (Various brands) Various

To change the spark plug on the Yamaha Majesty 250 motorcycle, remove the under-seat panel by unscrewing the four 10mm bolts as shown in the video. To keep the seat open, find a support to prop it up for easier access. Remove the under-seat panel and with a 5mm Allen key, unscrew the bracket as seen in the video to reach the spark plug. Move the tube and, applying some pressure, remove the 'cap' that protects the spark plug. Using the standard kit provided by Yamaha, use the tool to remove the spark plug. Once removed, you can screw in the new one, reinsert the cap, and reassemble all the bolts and brackets removed.
