Suzuki is working on an updated 250 cc parallel-twin engine which is supposed to comply with the stricter Euro 5 emission standards. The newly leaked patent images hint on the changes which will go inside the updated twin-cylinder powerplant.

The quarter-litre SOHC engine already comes equipped with a catalytic converter which is positioned underneath the engine bay. However, another catalytic converter has been placed closer to the exhaust ports and engine cylinder head.

Since the newly added cat-con has been placed closer to the exhaust ports, the pipes have been given a new design, merging mid-way, unlike before. Also, the patent images reveal that the new catalytic converter features two oxygen sensors which keep the exhaust gases in-check.

Currently, the company features its 250 cc parallel-twin powerplant in the bikes such as the GSX250R, V-Strom 250, and the GW250 Inazuma. The updated engine will serve all these motorcycles, making them complaint to the stricter Euro-5 emission standards.

In other developments, the company has launched the India-made Gixxer SF 250 and the Gixxer 250 motorcycles in Japan. Both the bikes retail at 481,800 yen ( 3.30 lakh) and 448,800 yen ( 3.07 lakh), respectively.
