Euro 5 only applies to the manufacturers homologation.

It is not possible to do an emission check on a bike with a legal exhaust as the sniffer probe must go into the exhaust system at least 50cm to eliminate the possibility that the exhaust is diluted by air. The way bike silencers are fitted with baffles the probe will not go in.

The only way to read the mixture is to either take data from the ECU or sample from a lambda probe. Both would require new, expensive, equipment at bike MOT stations. Who pays?

When VOSA consulted informally on this issue in 2008 they concluded that either VOSA would have to take over all bike MOT testing or there would be only about 20 bike MOT stations in the UK. My understanding is they walked away from the issue.

As far as the M3W is concerned no one knows yet what will happen. I suppose it can be MOTd by a car MOT station but they will not be able to check the brakes as no MOT brake tester can do a single rear wheel. Looks like fun!
