NGK plugs and there numbers are quite easy to understand and I find them to be the best quality. The CR9E plugs are a cooler running plug than the CR8E...meaning that it can work at higher temps due to higher c/r or slightly leaner fueling or constant high revs....from my 2stroke days, I found that NGK "V" type plugs worked and lasted very well..these were the racing plugs of the day, Iridium seems to be todays race plug, iridium being very durable. But if you`re not using high revs all the time, and a sv650 on the road really dosen`t need to be rev`d hard to make progress, a CR8E or even a CR7E plug may be more suitable, as they will self clean better at low revs and during warming up..just listen for any detonation if your using a hotter plug like a 7 tho I don`t think it will be a problem.
