NGK BPRES spark plugs are 14mm short thread resistor type with extended electrodes. This is the BPR7ES.
Numbers correspond to the temperature of the spark. 5 is the hottest and 10 is the coolest. stock mopeds will generally run a 5 or 6, kitted mopeds maybe a 7 or 8, high compression kits may want a 9 or 10. OEM quality, triple-gasket sealing process, consistent performance, plug of choice in millions of mopeds!
1977 - 1981 Honda NA and NC express mopeds had a BP4HS on the stock motor.
