The Bajaj Pulsar 200 NS is now in its second generation. The Pulsar has taken a massive leap in terms of engine refinement, handling, braking and performance. However some people are not too sure about the technology used in the motorcycle. We have often got questions about why the Pulsar 200 NS has triple spark plugs? Many people even ask that when the KTM Duke 200 has one spark plug and the Kawasaki Ninja 650R has two spark plugs (being a twin-cylinder bike), why does Bajaj Auto use three spark plugs in the Pulsar 200 NS? The question does hold weight-age as prospective buyers would want to know about the technology used in their bike. We got in touch with Bajaj Auto and they told us why they used triple spark plugs in the new Pulsar.

As can be seen in the above picture, the Pulsar 200 NS’ engine has two slave plugs (similar in spec) on either side and one master plug on the top. Twin spark plugs on either side are in-adequate to achieve the combustion efficiency which Bajaj engineers were looking for in the 200 NS. Thus the need for a center spark plug was felt by the engineers. Bajaj says that if the Pulsar 200 NS had only twin spark plugs, the combustion efficiency would be better than single spark plug by 18%. However with triple spark plug the efficiency is better by 27% than the twin spark plugs.
Bajaj Auto has used a ‘over-square’ configuration in the Pulsar 200 NS (bore x stroke of 72 x 49). The old Pulsar 200 had a bore x stroke of 67 x 56.4 which was a square configuration. The reason to opt for a ‘over-square’ configuration is for better top end performance, which is facilitated by the 4-valves, the company claims. So overall, the triple spark plugs are touted to improve combustion, thereby boosting performance and at the same time maintaining a good fuel economy for the Pulsar 200 NS.
