It only needs 7kV to jump the gap on a Spark plug.

The 2017 SV650s come with NGK MR8E-9 Platinum plugs.

Also I like to take my plugs out and check them from time-to-time as they give a good indication of how the engine/mixture is running but it's easier for me to get to my front plug on a,"Naked" and especially as I've removed the horn bracket and only have to remove the three Rad bolts and push the Rad forward.

At the end of the day it's down to what the user finds runs best for their machine.My 1999 curvy runs better on standard copper Plugs.
