These spark plugs are recommended by Yamaha for the newer models. They are original and it's a shame that even such spark plugs are being copied by Chinese companies. Please be aware that the R stands for the resistor. You have another resistor in your spark plug caps One is enough, otherwise the spark will be less powerful to ignite the fuel/air mixture. I can only reckon these plugs, not expensive and original. The attached photo shows a plug with two resistors.

I've ridden them and they are called BPR & ES because they have a resistor inside about 6 K Ohm. You do not need the BPR 7 ES when your bike has resistor caps. Too many resistors will make the spark less bright and strong, the bike will start not as good as only running one resistor. It's easy to measure with an ohm meter. If your spark plug caps have 6 K Ohm, then order the BPP 7 Es spark plugs and your bike will run fine. These bikes run better with such plugs, no need to pay a lot of money for Iridium plugs. And you can "read these plugs much better. The plugs are real, no fake ones made in China, that's for sure. Webike get their stuff from japan, and that's good to know. Be careful when plugs are too cheap, China copies pretty much all plugs and it's impossible to see if it's a real one, or a fake. The problem with fake plugs is that parts can fall into the combustion chamber and destroy your valves and pistons. E-bay sells way too many fake spark plugs, even the sellers of fake plugs warn you that there are copies out there. be alert! View detail
Good idea?
The Windshield IRIDIUM is not compatible with my motorcycle, so this plug is fine.
I'm using this as a guide because after about 5,000k miles, it's a bit CUBby even at mid-rotation cruising.
