2021 Emissions standards for bikes
Discussion
Morning all. I am looking to buy a new bike this year and am confused by the emissions requirements. I'm wondering if I am missing something as it appears to be that all bikes sold in 2021 have to be Euro 5 compliant.
Am I right in my understanding of this as it has to be Euro 5 now?
If so it appears that still most bikes advertised are Euro 4....
Still confused.

There's always a crossover period where manufacturers are allowed to clear out pre-built stock.

Euro 5: the immediate implications
The clearest thing to draw from Euro 5 is that, with new models that go on sale on or after 1st January 2020 being required to comply, it’s going to be a huge talking point when next year’s machines are unveiled towards the end of 2019.
It means we’re going to see a proliferation of technology like variable valve timing and lift, and perhaps a renewed thrust towards turbocharged machines like the long-promised Suzuki Recursion.
However, the bigger hit is likely to emerge 12 months later, with existing models being required to comply from 1st January 2021. At the moment, there’s no word from the EU on whether firms will be allowed derogation – a period of grace to sell-off limited numbers of non-compliant old models. Under Euro 4, the EU allowed a two-year derogation period after its January 2017 enforcement date, which meant bikes like Suzuki’s non-compliant Hayabusa remained in showrooms right up until the end of 2019. No doubt there will be an increasing clamour for a similar arrangement under Euro 5 as its implementation date draws closer.

bennets are pretty good in being a source of truth.
