I use D8EA as my standard plug.
DPR8EA 9 costs more.
D= 12mm thread (C=10mm; B=14mm)
P= projecting middle electrode
R= resistor, Spark arrested, better for the radio - do you have a radio on the bike?
8= heat range. running from 5 = very hot to 10= very cold
E= 19mm thread length
A= normal type; S= standrad type = pretty much the same thing. IX= iridium , VX = platinum
9= 0,9mm gap - a number here gives the gap
so D8EA is a 12mm thread 19mm long without resisitor and with the most normal type electrode imaginable.
cheapest thing available and more that good enough. I used them even from racing.
