Changing the plugs on my MY05 Rocket but I'm finding contradictory info re correct NGK plugs (I'm not going to iridium's or silver either)
Triumph service manual states DPR7 but manual is not specific to the MY05 model.
Other references state DPR8 which is the same physical size as the 7 but a hotter plug.

Anyone?
 
DPR8 EA-9 is the latest recommendation from Triumph. Originally it was DPR7 EA-9.
