I have a 2007 XL1200R. I replaced the stock 6R12 Harley Davidson plugs with NGK iridium at 4,747 miles. Wow!! What a difference!The bike used to turn over a few times when starting. Now I just touch the stater and it fires. Smoother idle and smoother at 2,000 to 4,000 rpm

great product; Comes from the factory with them, why use anything else. Had 26,000 miles on original set, no problems. Replaced for maintenance, don't recommend anything else.

Good price for OEM replacement plugs for my 04 Goldwing.

I'm an e3 fan. however, matching these to bike didn't tell me that I'd need a non-standard plug socket. Now I must figure out how to deal with that since it is not "for the bike" sized. Also, no mention that I'd have to de-thread the "car" plug wire socket so it would fit on the bike. While I love the e3 stuff, and the bike after 1/2 tank seems to like the plugs, these were not the drop and swap that were advertised. Plug wire caps required vice grips to remove (x 6 plugs) and it took a bit to figure out that metric sockets were not going to cut it for this. Better comments, packaging and socket sizing would be good if you are going to "right size"
