NGK R CR7E IX iridium plug.
But there won't be any noticeable change in performance.Yes the bike will start quickly and it might give a bit more on the avg.
The bigger benefit which will have on the RTR will be that the NGK CR7E series of plugs will be colder than the stock twin electrode one.That's because of the protruding center electrode of the Bosch ,were as the NGK R CR7E series of plugs have a center electrode which sits flush.So yes it will make the engine run colder in higher revs,which is a good thing,especially while touring.
Which is better? from what i know and seen NGK CR7E being a colder plug certainly is a better option for those who love to rip their rides.There will be a very slight(hardly noticeable) drop in initial pick-up though.


okie bro. 
Today,when i started the bike with the gears engaged,it didn't respond.After that i switched the engine kill switch on/off many times and sometime the bike started with the gears engaged and sometimes it didn't.
No problem what so ever in using em alone!!
Gurus please come to my rescue
