Suzuki is developing the Euro 5-compliant version of its existing 250cc parallel-twin engine, and leaked images of new motor have surfaced online. Suzuki has also applied for a patent for its new 250cc engine and as the images suggest they've put their best brains to use in order to ensure that the engine conforms to the strict Euro 5/ BS6 emission regulations. But before we go any further let us remind you that this 250cc parallel twin has been around for quite some time and also powered the critically acclaimed Suzuki Inazuma. The engine developed 26hp and 22Nm while it's smooth nature and crisp power delivery was lauded by many. However, that did little to push the Inazuma's sales in India, as many felt that it was overpriced. Besides the Inazuma, this engine also powered the Suzuki GSX250R and the V-strom 250.
Coming back to the new 250cc parallel-twin engine, Suzuki has employed a secondary catalytic converter that's located just after the point where the two exhaust header pipes emerge out of the combustion chambers. The two pipes converge into the cylindrical catalytic converter and split as they exit it, onwards to the larger catalytic converter that's part of the exhaust system.
This is one popular way of ensuring engines meet the new emission norms, and we've seen similar methods employed in single-cylinder engines on BS6 motorcycles that are on sale in India, case in point being the Suzuki Gixxer series.
While there are rumours about Suzuki introducing the new parallel-twin engine in the Gixxer 250 SF that's one sale in India, we don't think that will happen. In fact, Suzuki has specifically developed the 249cc, single-cylinder engine for the Gixxer 250 / Gixxer 250 SF and has recently upgraded it to Euro 5/ BS6 emission standards. We also believe that if Suzuki were to introduce the V-strom 250 or Intruder 250 in India, it will employ this single-cylinder engine, instead of the Euro 5 parallel-twin engine that will power bikes in the international market.
