Denso U27ETR The spark plug gap should be 0.6-0.7mm (0.024-0.028in) for both models. Dual electrode plugs do not really enhance performance but offer longer life than single electrode plugs. The JR9C plugs can be used on the Bandit 1200 without problem and give faster starts and better idle and a slight bit more compression.
Another option is Autolite #4162 spark plugs which fit exactly the same and are
usually cheaper than NGK's. FOR MORE INFO ON BANDITS SEARCH "FAST LARRY'S BANDITS"
