I bought it for a replacement cycle after replacing it last time and riding it for about 5000km.
I'm not an expert, but after replacing it with the DX last time, the throttle response improved and I felt that the ride was better than using the genuine one, so I bought an additional replacement after 5000km.
Unless there is a big problem, I think I will probably continue to purchase and use the MOTO DX.
2019 DL1000 V-STROM 650, first replacement at 15,000 km. The plug that was removed was still usable with proper Gap, minimal Edge wear, and good burn color.The difference from the MotoDX replacement is a little smoother? I think the only difference is that the MotoDX is a little smoother and the Merit is long life. I didn't expect any improvement in running performance, and what is the basis for the short life of the StandardPlug that PlugManufacturer says? I doubt it.
Motorcycle-only Plug is something I would like to include. I put it in with BirdCity's Refresh.
The fuel consumption seems to have improved, although it is not more than 2 km per liter. I honestly didn't know about Torque, etc., but I was excited because I didn't think I would be replacing the Scooter plugs very often.
I bought this for my PCX150KF30 Stock. Please note that the compatible plug is different from KF12 and KF18. Denso offers three types:standard, Iridium Power, and Iridium racing, while NGK offers only standard. NGK was the only company available on Webike, so we had no choice. I haven't replaced it yet, so I don't know how it feels, but I don't feel the need to use Windshield IRIDIUM on my Scooter, so I think this is fine.
I replaced it after driving about 6000km with OEMPlug. The Torque is low, so be careful not to over-tighten. You can see that the Idling has stabilized and the Engine is more powerful. In addition, the mileage has also improved by about 1~2km. It is a little expensive, but I think that it is good to choose this Plug if the Plug exchange time has come.
