No Honda motorcycle has resistor wires. Some are stranded copper, some are stranded stainless steel. All are considered permanent. Despite some other manufacturer's use of them, resistive wire is bad news on a motorcycle.
Resistor caps are another story. They were a development on road bikes only for RFI issues. On dirt bikes, they had some additonal benefits and reasons. Resistor plugs were used on many road bikes starting in the late 70s, but by Honda's own admission, they appeared on Hondas only because it made economic sense to include U.S. models in what became in the 80s a Euro requirement, again RF-related. Late model bikes with fuel injection and/or engine management systems are entirely another story. They have higher resistive caps than earlier models, and of course resistive plugs as well, as do all Hondas from the early 80s onward. The electronics on these machines are protected thereby.
The purpose of both resistor caps and plugs is to dampen a byproduct of ignition coil action that produces radio waves, radio frequency interference actually, RFI, with the downside some slight reduction in ignition intensity, though not enough to matter on an otherwise well-kept machine. Therefore, going non-resistor can in fact boost ignition potential, a complicated subject in itself, but not necessarily actual performance unless other factors are in place.
