Motorcycles

In the 1990s, the Korean government introduced emissions standards for two-stroke and four-stroke motorcycles requiring the use of catalytic converters.

The emission standards were then tightened by introducing Euro 2 and Euro 3 standards from January 2008.

From January 2017, the government implemented Euro 4 emissions standards for all motorcycles registered in South Korea and, as of January 2020, Euro 5 emission standards were implemented (see table below).

In October 2021, the Seoul Municipality announced its plan to replace all motorcycles powered by internal combustion engines with electric ones by 2025. The plan included distributing 62,000 electric motorcycles by 2025. Of these, 35,000 units would be dedicated to delivery services that operate for more than five days a week
