I chanced upon these 2 old articles.

The first talks about EURO IV compliant for new motorcycles registered from 1 Jan 2018 onwards. I heard that all air-cooled engines cannot meet Euro IV standard (which is a relatively big step from Euro III). Means no air-cool engine for Singapre from next year onwards??

SINGAPORE: Emission standards for new motorcycles will be tightened to meet the latest Euro 4 standards, announced Environment and Water Resources Minister Masagos Zulkifli on Tuesday (Apr 12), at his ministry’s Committee of Supply of Debate in parliament.
“Motorcycles are significant contributors to carbon monoxide and ozone. We need to raise their emission standards in step with improvements in technology,” the minister said.
The new standards will be introduced in phases. They will apply to large motorcycles above 200cc from January 2018 and for those of 200cc and below from January 2020.

The second talks about tightening of the emission standard for motorcycles registered after 1 Apr 2014, means existing motrorcycles to meet certain emission standard, although it did not state what standard (Euro I, II or III). My scooter met Euro III WHEN NEW but now don't know. I am not if it can pass the annual inspection now.

Currently, the exhaust emission standards for petrol vehicles and motorcycles only specify limits for carbon monoxide emissions. From April 1, 2018, carbon monoxide limits will be lowered for newer petrol vehicles (registered from Jan 1, 2001, and from April 1, 2014) and motorcycles (registered from Oct 1, 2014).

New hydrocarbon limits will be introduced for all petrol vehicles and most motorcycles.
